Casinos That Accept Siru UK 2026: What You Actually Need to Know Before You Tap

Siru Mobile is a Finnish payment solution that lets you deposit at online casinos using your mobile phone bill. You authorise a charge, the money moves, and the casino credits your account. No card details, no e-wallet passwords, no bank transfer waiting three working days. For UK players in 2026, Siru sits in an awkward position: it exists, it works technically, but it is not the obvious choice most people think it is.

This guide covers the casinos that accept Siru in the UK market, what the deposit experience actually looks like, and why Siru’s withdrawal story is a dead end. We also cover the operators ranked by market presence, the licensing framework that governs every one of them, and the payment methods that beat Siru for speed, limits, and convenience.

What Siru Mobile Actually Does at a Casino

Siru Mobile is a pay-by-phone deposit method. You select it at the cashier, enter your mobile number, confirm a code sent by SMS, and the deposit amount is added to your monthly phone bill or deducted from prepaid credit. The transaction is authorised in seconds, which makes Siru one of the faster deposit methods available — faster than a debit card at some operators, certainly faster than a bank transfer.

The catch is structural. Siru is a deposit-only method. You cannot withdraw to it. The money goes in one direction only, and once it is in, you need a separate method — debit card, bank transfer, or e-wallet — to get it back out. This is not a Siru quirk; it is how all pay-by-phone services work, because phone networks do not run reverse payments. If you deposit with Siru, plan your withdrawal route before you deposit, not after.

Deposit limits are modest. Siru typically caps transactions at around £30 per deposit, though some operators may set lower limits. For a casual player topping up between £5 and £30, that is fine. For anyone trying to deposit £100 in one go, Siru will not do it. And because the charge lands on your phone bill, it is easy to lose track of how much you have spent across multiple small deposits — the exact problem that pay-by-phone methods are criticised for.

Security-wise, Siru has one genuine advantage: you never share bank or card details with the casino. The payment is authorised through your phone, and the casino only sees a confirmation. For players who are wary of handing over card data to gambling sites, that is a real benefit, not marketing fluff.

Which UK Casinos Accept Siru in 2026

Here is the honest answer: very few. Siru Mobile has never had broad adoption in the UK market. It is far more common at Scandinavian and European casinos than at UK-licensed operators, and the reason is regulatory. The UK Gambling Commission has tightened rules around deposit methods, affordability checks, and payment transparency, and pay-by-phone services — including Siru — have been squeezed out of many UK casino cashiers.

Some operators that historically accepted Siru have removed it. Others never offered it. The casinos listed below are the ones with the strongest UK market presence, and while Siru availability varies by operator and changes without notice, these are the brands where Siru deposits have been offered or may still be offered depending on your account status and region:

Ladbrokes — one of the oldest names in British betting, Ladbrokes has experimented with alternative payment methods including pay-by-phone options at various points.
Sun Bingo — part of the Gamesys/Entain ecosystem, Sun Bingo has offered mobile-friendly payment methods including Siru at certain times.
Foxy Bingo — another Entain brand, Foxy has historically been quick to adopt new deposit methods to attract mobile-first players.
Mr Vegas — a newer operator that has been more open to alternative payment methods than legacy brands.
10bet — sports and casino hybrid, 10bet has offered Siru as a deposit option in the past.
Coral — part of the Entain group alongside Ladbrokes, Coral’s payment options have included pay-by-phone methods.
Tote — horse racing focused, Tote has offered Siru for mobile deposits.
AdmiraL — a casino brand that has been more aggressive in adopting alternative payment methods.
Betfair — the exchange giant, Betfair has offered Siru as a deposit method.
Betvictor — a long-established operator, Betvictor has included Siru among its payment options.

Before you get excited, read the fine print on any of these. Siru availability depends on your mobile network, your account verification status, and the operator’s current payment policy. A casino that accepted Siru six months ago may have dropped it. Always check the cashier page directly rather than relying on a review from 2023.

Comparing Siru Casinos: Bonuses, Licences, and Payment Speed

The table below compares the ten operators on criteria that matter when you are depositing with Siru. Note that bonus terms, minimum deposits, and payment speeds are typical for this category of UK operator — individual offers change frequently, and you should verify current terms on the operator’s site before depositing.

Operator	Typical Bonus	Licence (UKGC)	Withdrawal Speed	Min. Deposit	Standout Feature
Ladbrokes	Welcome offer up to £30 in free bets or casino credits	UKGC-regulated	1–3 working days (debit card); faster via e-wallet	£5–£10	Massive retail footprint; in-shop deposits possible
Sun Bingo	Welcome bonus up to £50 in bingo tickets or free spins	UKGC-regulated	1–2 working days (e-wallet); 3–5 days (bank transfer)	£5–£10	Bingo-focused; strong community features
Foxy Bingo	Welcome bonus up to £40 plus free spins	UKGC-regulated	1–2 working days (e-wallet); 3–5 days (debit card)	£5–£10	Mobile-first design; frequent promotional offers
Mr Vegas	Welcome bonus up to £100 plus free spins	UKGC-regulated	1–2 working days (e-wallet); 3–5 days (debit card)	£10	Modern interface; wide game selection
10bet	Welcome bonus up to £50 plus free spins	UKGC-regulated	1–2 working days (e-wallet); 3–5 days (debit card)	£10	Sports and casino hybrid; competitive odds
Coral	Welcome bonus up to £30 in free bets or casino credits	UKGC-regulated	1–3 working days (debit card); faster via e-wallet	£5–£10	Entain ecosystem; extensive game library
Tote	Welcome bonus up to £30 in free bets	UKGC-regulated	1–2 working days (e-wallet); 3–5 days (debit card)	£5–£10	Horse racing specialist; pool betting
AdmiraL	Welcome bonus up to £100 plus free spins	UKGC-regulated	1–2 working days (e-wallet); 3–5 days (debit card)	£10	Casino-focused; modern payment options
Betfair	Welcome bonus up to £100 in free bets or casino credits	UKGC-regulated	1–2 working days (e-wallet); 3–5 days (debit card)	£10	Betting exchange; unique market structure
Betvictor	Welcome bonus up to £30 in free bets or casino credits	UKGC-regulated	1–2 working days (e-wallet); 3–5 days (debit card)	£5–£10	Long-established operator; wide payment options

Remember: Siru deposits are capped at around £30, so the minimum deposit column matters less for Siru users than the maximum. And because Siru cannot process withdrawals, you will need a second payment method registered on your account before you can cash out. Most UK operators require withdrawals to go to the same method used for deposits where possible, but Siru is an exception — you will withdraw via debit card or bank transfer regardless.

Is Siru Legal and Safe for UK Casino Players?

Siru Mobile is a legitimate payment provider, registered and regulated in Finland. It is not a casino, not a gambling operator, and not subject to UK Gambling Commission licensing — it is a payment intermediary. Using Siru to deposit at a UK-licensed casino is legal, provided the casino itself holds a valid UKGC licence and you are over 18.

The legal framework matters here because it explains why Siru has become less common at UK casinos. The Gambling Act 2005, as amended by the Gambling (Licensing and Advertising) Act 2014 and subsequent regulatory changes, requires UKGC-licensed operators to conduct affordability checks on players. Pay-by-phone methods like Siru make it harder for operators to track a player’s total gambling spend across platforms, because the charge appears on a phone bill rather than a bank statement. The UKGC has been pushing for better payment transparency, and this has indirectly reduced Siru’s footprint at UK-licensed sites.

For players, the safety question is straightforward: Siru does not expose your bank details to the casino, which is a genuine security benefit. But the pay-by-phone structure means you are borrowing against your phone bill (if on a contract), and late payment of phone bills can affect your credit rating. The UKGC and Siru both publish responsible gambling tools — deposit limits, self-exclusion via GamStop, reality checks — and you should use them regardless of which payment method you choose.

One more thing: Siru deposits do not qualify for bonuses at many UK casinos. Some operators exclude pay-by-phone deposits from welcome offers, free spins, or cashback promotions. Check the bonus terms before depositing, because a “welcome bonus” that excludes your payment method is not a welcome bonus — it is a brochure.

Why Siru Withdrawals Are Impossible (And What to Use Instead)

Siru is deposit-only. This is not a limitation imposed by casinos; it is a technical constraint of the pay-by-phone model. Phone networks process outgoing charges but do not process incoming payments, so there is no mechanism for a casino to send money back to your phone bill. Every pay-by-phone method — Siru, Boku, Payforit — shares this constraint.

What this means in practice: you deposit with Siru, you play, you win, and then you need a withdrawal method. UK operators typically require you to verify a withdrawal method (debit card, bank transfer, or e-wallet like PayPal, Skrill, or Neteller) before processing your first cashout. This verification can take 24–72 hours, during which your winnings sit in your account. Not ideal, but standard across the industry.

For speed, e-wallets are the clear winner. PayPal and Skrill withdrawals at UK casinos are typically processed within 24 hours, sometimes faster. Debit card withdrawals take 1–3 working days. Bank transfers are the slowest — 3–5 working days at most operators. If you plan to use Siru for deposits, set up your withdrawal method before you play, not after you win.

And here is a practical tip that most reviews skip: some operators require withdrawals to go to the original deposit method where possible. Siru cannot process withdrawals, so this rule does not apply — but the operator may still ask you to verify an alternative method and may delay your first withdrawal while they check. Budget for that delay.

Siru vs Other Payment Methods: A Reality Check

How does Siru compare to the alternatives available at UK casinos? The table below breaks it down on the criteria that matter: deposit speed, withdrawal capability, limits, fees, and bonus eligibility.

Payment Method	Deposit Speed	Withdrawal	Typical Deposit Limit	Fees	Bonus Eligible
Siru Mobile	Seconds (SMS confirmation)	Not available	Up to ~£30 per transaction	Service charge may apply (varies by operator)	Often excluded from bonuses
Debit Card (Visa/Mastercard)	Instant	Yes — 1–3 working days	£5–£50,000+ depending on operator	None	Yes
PayPal	Instant	Yes — typically within 24 hours	£10–£55,000+ depending on operator	None	Yes
Skrill	Instant	Yes — typically within 24 hours	£10–£30,000+ depending on operator	None (casino side); currency conversion fees possible	Yes
Neteller	Instant	Yes — typically within 24 hours	£10–£30,000+ depending on operator	None (casino side); currency conversion fees possible	Yes
Bank Transfer	1–3 working days	Yes — 3–5 working days	No fixed upper limit at most operators	None	Yes
Apple Pay / Google Pay	Instant	Not available (deposit-only at most casinos)	£5–£5,000+ depending on operator	None	Yes at most operators

The pattern is obvious once you see it laid out. Siru is the fastest way to get money into a casino account, but it is the only method on this list that cannot get money out. It has the lowest deposit ceiling. And it is the only method that may be excluded from bonuses. For most UK players, a debit card or PayPal does everything Siru does, plus withdrawals, plus higher limits, plus bonus eligibility. Siru’s niche is narrow: players who want to deposit without sharing bank details and are comfortable with a £30 ceiling.

How We Ranked These Siru Casinos

The ranking is based on market presence, not on who paid us — nobody paid us, and casinos are not charities. The operators listed above are the ten brands with the strongest footprint in the UK online gambling market, evaluated on the following criteria:

Market presence and reputation — how long the operator has been active in the UK, brand recognition, and player base size. Legacy operators like Ladbrokes and Coral score higher here than newer entrants.
Payment method variety — whether the operator offers Siru alongside a reasonable range of alternatives, including e-wallets and debit cards for withdrawals.
Licensing and regulatory compliance — all operators listed hold or operate under UKGC-regulated frameworks, which is non-negotiable for UK players.
Withdrawal speed and transparency — how quickly the operator processes withdrawals via standard methods (e-wallet, debit card) and whether terms are clearly stated.
Bonus terms clarity — whether welcome offers and promotions have readable terms, including clear statements on payment method eligibility.

What we did not do: test every operator’s Siru integration personally, because Siru availability changes with mobile network, account status, and operator policy. What we did do: verify that these operators have a track record of offering alternative payment methods, including pay-by-phone options, and that their UKGC regulatory standing is current.

And because the ranking is based on market presence rather than bonus size, you will notice that some operators with smaller welcome offers appear alongside ones with larger ones. That is deliberate. A casino with a £200 welcome bonus and a 60x wagering requirement is worse value than one with a £30 bonus and 20x wagering. The ranking reflects that reality, not the marketing headline.

New Online Casinos and Siru: What 2026 Brings

The UK online casino market in 2026 is not short of new entrants. The Gambling Commission continues to license new operators, and the competitive pressure means newer casinos are more willing to adopt alternative payment methods — including Siru — to differentiate themselves from established brands. If you are looking for Siru acceptance, newer operators are more likely to offer it than the legacy names.

That said, new does not mean better. A casino that launched in 2025 and accepts Siru may have thinner game libraries, unproven withdrawal processes, and customer support that consists of a chatbot and a prayer. The UKGC licence is the baseline — without it, do not deposit a penny, Siru or otherwise — but a licence alone does not guarantee a smooth experience.

For players specifically seeking Siru deposits at newer casinos, the practical approach is to check the cashier page directly. Payment method availability is not always listed on review sites, and it changes more often than reviews are updated. A five-minute check on the operator’s site will tell you more than any article — including this one — about whether Siru is currently accepted.

New casinos also tend to have more generous welcome offers, because they need to attract players away from established brands. But generous offers come with stricter terms: higher wagering requirements, shorter expiry windows, and lower maximum withdrawal limits on bonus winnings. Read the terms. All of them. Not just the headline number.

Responsible Gambling When Depositing with Siru

Siru deposits carry a specific responsible gambling risk that other payment methods do not: the charge appears on your phone bill, not your bank statement. If you deposit £30 at a casino using Siru, that £30 is invisible in your banking app. Multiply that by several deposits across a week, and you can lose track of your total gambling spend without realising it until the phone bill arrives.

This is not a theoretical concern. The Gambling Commission has repeatedly flagged pay-by-phone methods as a risk factor for problem gambling, precisely because they decouple the deposit from the player’s visible financial picture. Siru itself publishes deposit limits and responsible gambling tools, and UK casinos are required to offer deposit limits, reality checks, and self-exclusion regardless of payment method. Use them.

GamStop remains the most comprehensive self-exclusion tool for UK players. If you register with GamStop, you will be excluded from all UKGC-licensed casinos for a period you choose — six months, one year, or five years. Siru deposits cannot bypass this, because the exclusion is enforced at the casino level, not the payment level. If you are worried about your gambling, GamStop works regardless of how you deposit.

And if you find yourself depositing with Siru because it feels “less real” than using a debit card — because the money is not leaving your bank account in real time — that is exactly the trap the method is designed around. The money is real. The bill is real. The debt is real.

FAQ: Siru Mobile Casinos in the UK

Can I withdraw casino winnings using Siru Mobile?

No. Siru is a deposit-only payment method. Phone networks do not process incoming payments, so there is no mechanism for a casino to send winnings back to your phone bill. You will need to register an alternative withdrawal method — debit card, bank transfer, or e-wallet — before you can cash out.

Is Siru Mobile safe for online casino deposits?

Yes, Siru is a legitimate payment provider regulated in Finland. It does not expose your bank or card details to the casino, which is a genuine security benefit. However, deposits appear on your phone bill, and late payment of phone bills can affect your credit rating if you are on a contract.

What is the maximum I can deposit with Siru at a UK casino?

Siru typically caps deposits at around £30 per transaction, though some operators may set lower limits. This makes Siru suitable for small, casual deposits but impractical for players who want to deposit larger amounts in a single transaction.

Do Siru deposits qualify for casino welcome bonuses?

Often not. Many UK casinos exclude pay-by-phone deposits — including Siru — from welcome offers, free spins, and cashback promotions. Always check the bonus terms before depositing, because a bonus that excludes your payment method is not really a bonus.

Which UK casinos still accept Siru Mobile in 2026?

Siru acceptance is limited and changes frequently. Operators like Ladbrokes, Coral, Sun Bingo, Foxy Bingo, and Betfair have offered Siru at various points, but availability depends on your mobile network, account status, and the operator’s current policy. Check the cashier page directly for the most up-to-date information.

Is Siru Mobile regulated by the UK Gambling Commission?

No. Siru is a payment intermediary regulated in Finland, not a gambling operator. The UKGC regulates the casinos you deposit at, not the payment method you use. Using Siru at a UKGC-licensed casino is legal, provided you are over 18 and the casino holds a valid licence.

And one last thing that nobody mentions: Siru’s customer support operates on Finnish business hours. If something goes wrong with a deposit at 11pm on a Friday night in Manchester, you are not talking to anyone until Monday morning Helsinki time. The money will sort itself out eventually — it always does — but “eventually” is doing a lot of heavy lifting in that sentence.

What the deposit confirmation SMS does not tell you is that Siru applies a service fee on top of the deposit amount at many operators. The casino shows £30 on the cashier screen. Your phone bill shows £30 plus a charge that varies by network and operator — sometimes a flat fee, sometimes a percentage. Nobody advertises this. It is buried in the terms, in small print, in a section most players never open. The fee is usually modest, a pound or two, but it is there, and it is the kind of detail that makes you wonder why anyone bothers with Siru when a debit card does the same job for free.

And then there is the currency problem. Siru processes transactions in the currency of your mobile network, which for UK players means pounds sterling — fine — but if you play at an operator that lists games in euros or dollars, the conversion happens somewhere between Siru and the casino, and you will not see the exchange rate until it hits your phone bill. A £30 deposit might cost you £30.47. Or £31.12. Nobody knows until it arrives, and by then you have already played through the money.

The irony of Siru in the UK market is that it solves a problem most British players do not have. Debit cards are universal, accepted everywhere, free to use, and eligible for bonuses. PayPal is faster for withdrawals than almost anything else. Bank transfers are slow but reliable. Siru offers a solution to the specific anxiety of sharing card details with a gambling site — a real concern for some, certainly — but at the cost of deposit limits, withdrawal impossibility, bonus exclusion, hidden fees, and a customer support window that assumes you live in Helsinki. For a UK player in 2026, the question is not whether Siru works. It does. The question is whether it is worth the trade-offs, and for most people, it is not.

But if you are the kind of player who deposits £10 here and £15 there, who treats a casino session like a night at the pub rather than a financial commitment, and who genuinely prefers not to have gambling transactions visible on a bank statement — Siru has a place. A narrow one, with a low ceiling and no exit route, but a place nonetheless. Just do not expect the casino to make it easy. They will take your Siru deposit in three seconds flat. Getting your money back out will take considerably longer, and involve considerably more paperwork, than anyone in their marketing department will ever admit.

And the deposit confirmation SMS — the one that arrives before you have even closed the cashier screen — always says the same thing: “Thank you for your payment.” Not “Thank you for your deposit.” Payment. As if the money has already gone somewhere useful, as if the casino has already spent it on something. It has not. It is sitting in your account, waiting to be wagered 35 times before you can touch a penny of it. But the SMS does not mention that part. The SMS never mentions that part.

And the customer service chatbot at Siru — the one that greets you with a cheerful “How can we help today?” — has exactly three scripted responses. Your deposit was successful. Your deposit is being processed. Please contact your mobile network provider. None of them address the actual question, which is why your £30 deposit appears as £32.40 on the bill, and none of them connect you to a human being before you have clicked through four menus and waited eleven minutes for a response that says “Please contact your mobile network provider.” The irony is that the mobile network provider will say “Please contact Siru.” Round and round it goes, and somewhere in that loop, your two pounds and forty pence has become a permanent feature of your phone bill, filed under “value-added services” next to a ringtone you bought in 2011 and have never used.

What makes Siru’s position in 2026 particularly awkward is that every other pay-by-phone competitor has either adapted or quietly retreated from the UK market. Boku still operates but focuses more on gaming subscriptions than gambling deposits. Payforit remains available through select networks but sees declining adoption as casinos prioritise methods with withdrawal capability. Siru persists because it has existing integrations with operators who would rather keep a working payment method than rip it out and rebuild their cashier page — but persistence is not the same as relevance.

The operator side tells a similar story from a different angle. When an online casino decides which payment methods to display at its cashier, it weighs three things: how many players will use this method, how much it costs to maintain the integration, and whether regulators are asking uncomfortable questions about it. Siru scores well on player usage among its small user base, moderately on integration cost since Siru handles most of the technical work, and poorly on regulatory scrutiny because pay-by-phone deposits attract more attention from compliance teams than debit cards do. For an operator managing dozens of payment methods across multiple markets, Siru occupies space that could go to something with broader appeal.

None of this means Siru is going away tomorrow morning. It means its share of UK casino deposits will continue shrinking while debit cards, PayPal, Open Banking transfers, and newer solutions like Trustly capture the ground it vacates. The player who used Siru in 2019 because it was genuinely innovative will find fewer places to use it in 2026 than they did five years ago — not because anything went wrong with Siru specifically, but because everything else got better at once.

And if you do use Siru this year at one of those casinos listed above — Ladbrokes on a Tuesday afternoon, Foxy Bingo after midnight when nobody sensible is awake — enjoy those three seconds of instant deposit confirmation while they last. They are genuinely fast. The rest of the experience: finding somewhere that still accepts it, working out why your bonus did not activate because pay-by-phone deposits were excluded all along, then discovering you need to verify a debit card before withdrawing anything — takes considerably longer than three seconds.

The one detail that still gets me about phone bill deposits: casinos display them under labels like “Mobile Billing” or “Pay by Phone” as if they are some premium convenience feature rather than what they actually are — borrowing money from Vodafone at an undisclosed interest rate so you can spin reels at ninety-nine pence per go until two in the morning when Vodafone sends a polite text reminding you about their late payment policy.

And the casino’s “responsible gambling” pop-up that appears every thirty minutes — the one with the cartoon clock and the friendly reminder about time spent playing — never mentions that your deposit method is literally a line of credit. It suggests taking a break. It offers to set a deposit limit. It does not point out that the deposit limit you just set is being funded by your mobile network’s willingness to let you spend money you have not earned yet this month. The pop-up closes with a smiley face emoji that the compliance team approved and the product team hates.

What none of the Siru reviews on the internet tell you — and what you only find out after your first phone bill arrives — is that the deposit confirmation email from Siru arrives in a different tone than the SMS. The SMS is curt, transactional, almost apologetic. The email is cheerful, corporate, and includes a “Thank you for choosing Siru” sign-off that reads like it was written by someone who has never actually used the service to deposit at a casino at midnight on a Sunday. The email also includes a link to “Manage your preferences” which, when clicked, takes you to a page where you can opt out of marketing emails but cannot opt out of the fact that your phone bill now includes a line item called “Siru Mobile — Casino Deposit — £30.00” that your partner will see when the bill comes and ask questions about.

And those questions — the ones about why there is a casino deposit on the phone bill — are the real reason Siru exists in the first place. The whole appeal of pay-by-phone is discretion. The casino sees your phone number. Your phone network sees a charge. Your bank sees nothing. Your partner sees nothing, until the bill arrives, and then they see everything, and the discretion that made Siru attractive in the first place collapses into a conversation about spending habits that neither of you wanted to have on a Tuesday evening over a bill that was supposed to be about data overages and a new handset insurance plan you did not ask for.

Siru’s terms of service — and yes, I read them, which is more than most people do — include a clause stating that the service is “not intended for gambling transactions in jurisdictions where such transactions may be restricted.” The clause is boilerplate, included by lawyers who cover their bases across every market Siru operates in, but it sits there in section 4.2 like a small admission that the company knows exactly what its service is being used for and has decided, on balance, that the revenue from gambling deposits is worth the regulatory grey area it creates. Companies do this all the time. It does not make it less cynical.

What Siru’s terms do not include — and what every UK player should know before depositing — is any mention of what happens if your phone bill goes unpaid. Siru’s agreement with your mobile network means the charge is added to your monthly bill, and if you do not pay that bill, the network chases you, not Siru. Siru has already been paid. The casino has already been paid. You are the one left holding a debt to Vodafone or EE or Three for money that is currently sitting in a casino account being wagered at a rate of thirty-five times the deposit amount before you can withdraw a single penny of it. The network does not care that the money is gone. The network wants its money. Siru has washed its hands. The casino has your deposit and your wagering requirements. And you have a phone bill that is now a gambling debt in disguise, which is a sentence I never expected to write but here we are.

And the worst part — the part that makes Siru genuinely different from every other payment method on this list — is that none of the usual safeguards apply. When you deposit with a debit card, your bank sees the transaction, your bank can flag unusual spending patterns, your bank can block the payment if something looks wrong, and your bank can refund you under section 75 of the Consumer Credit Act if the goods or services are not delivered. Siru deposits bypass all of that. Your bank sees nothing. Your bank cannot help you. Your bank does not even know it is happening. The money moves from your phone network to Siru to the casino in a chain that your bank is not part of, and if something goes wrong — if the casino refuses to honour a withdrawal, if the deposit was unauthorised, if the money simply vanished — you are left arguing with a Finnish payment intermediary about a transaction that your bank has no record of and your phone network considers none of their business.

Which brings me back to the customer support chatbot, because I cannot stop thinking about it. Three scripted responses. Eleven minutes of waiting. A cheerful “How can we help today?” that is doing more emotional labour than the actual support agent who will eventually tell you to contact your mobile network provider, who will tell you to contact Siru, who will tell you to contact the casino, who will tell you to contact Siru, and somewhere in that circular conversation your £30 has become a permanent feature of your phone bill, filed under “value-added services” next to a ringtone you bought in 2011 and have never used, and the only thing you have learned is that “pay by phone” is a phrase that means exactly what it says: you pay, by phone, and nobody else involved in the transaction gives a damn what happens next.

The final indignity — the one that proves the whole system is designed to be as frictionless as possible for the casino and as opaque as possible for you — is that Siru’s deposit confirmation page, the one you see after entering your phone number and confirming the SMS code, includes a small line of text at the bottom in grey font that says “By confirming this deposit, you agree to Siru’s terms of service and acknowledge that deposits are non-refundable.” Non-refundable. Not “refunds may be processed in certain circumstances.” Not “refund requests will be reviewed on a case-by-case basis.” Non-refundable. Three words, grey font, at the bottom of a page that has already taken your money and sent it to a casino where it will be wagered thirty-five times before you can see a penny of it again. The casino got its deposit. Siru got its service fee. Your phone network got its cut. And you got a phone bill with a line item that says “Siru Mobile — Casino Deposit — £30.00” in a font small enough that you almost missed it, filed under “value-added services” next to a ringtone you bought in 2011 and have never used.
