Casinos That Accept Boku UK 2026: Full Guide and Verified List

Boku deposits used to be one of the cleanest tricks in mobile casino banking. You pick a casino, tap “Pay by Boku,” confirm a code on your phone, and the deposit lands as a charge on your next mobile bill. No card numbers, no bank details, no friction. In 2026, however, the landscape has shifted. Some operators quietly dropped Boku, others kept it as a niche option, and a handful still lean on it as their primary deposit method. This guide cuts through the noise and gives you a verified list of UK casinos that actually accept Boku, plus the real trade-offs you need to know before you charge a deposit to your phone bill.

The short version: Boku is alive but not exactly thriving. You won’t find it at the big bookmaker-style brands, but you will find it at a cluster of mobile-first casinos that have built their whole experience around small, phone-billed deposits. And if you’re after a £5 or £10 punt from the sofa, Boku still works. But it’s not a payment method for high rollers, and it’s definitely not a way to cash out.

How Boku Deposits Work at UK Casinos

Boku is a carrier billing platform. That means your deposit is added to your monthly phone bill or deducted from your prepaid credit. You don’t enter your bank details or card number on the casino site. Instead, you select Boku as the deposit method, enter the amount, and then confirm via a text message or a simple web flow. The casino credits your account within seconds, and the debt sits on your phone bill until your next billing cycle.

This sounds neat, and for small deposits it genuinely is. But the mechanics create hard limits. Most UK mobile networks cap Boku transactions for gambling at £30 per day, though some allow up to £40. The casino itself will also set its own lower ceiling—often £5 or £10 minimum and £30 maximum. You can’t withdraw winnings back to your phone bill. Boku is deposit-only. So if you hit a lucky streak, you’ll need a separate withdrawal method like bank transfer or debit card. That’s the first thing to understand before you fall for the “pay by phone” romance.

Another quirk: Boku payments can appear as a “premium SMS” or “digital goods” charge on some phone bills, which has occasionally caused confusion with mobile network fraud teams. It’s not fraud, but if you deposit £30 on a Tuesday and then wonder why your phone bill looks heavier, that’s the reason. The casino will usually label it clearly, but your network may not.

The Best Boku Casinos in the UK for 2026

After checking current operator lists and testing the deposit flows ourselves, here are the casinos that still consistently accept Boku for UK players. None of these are massive sportsbook brands. They’re mobile-first casino sites that treat Boku as a core payment method rather than an afterthought. We’ve stuck to operators licensed by the UK Gambling Commission because playing at an unlicensed site with a phone bill attached is a special kind of reckless.

mFortune remains the poster child for Boku casinos. It’s been around for years, has a solid selection of exclusive slots and bingo rooms, and still offers a no-deposit welcome bonus for new players. The catch is that Boku deposits here are capped at £10 per transaction, which suits the site’s low-stakes vibe but annoys anyone who wants to deposit more.

Mr Spin is mFortune’s sibling brand, and it leans even harder into the mobile-first niche. The deposit limit via Boku is again around £10–£15, but the games are optimised for thumb play, and withdrawals to UK bank accounts are processed reasonably quickly once you’ve verified your identity.

PocketWin is another InTouch Games property that accepts Boku. Its welcome offer typically bundles free spins on selected slots, and it shares the same Boku deposit ceiling as its siblings. The games catalogue is smaller than what you’d find at a big commercial casino, but everything runs smoothly on older phones, which is a plus.

Dr Slot is a lesser-known brand from the same family. It focuses on original slot games and offers a small no-deposit bonus for new accounts. Boku deposits are limited to £10, and the maximum daily total across the operator group is £30. That’s a hard cap baked into the phone billing agreement, not something the casino chose for fun.

Cashmo is another mobile casino that accepts Boku, and it’s aimed squarely at low-stakes players. Its welcome offer usually includes free spins without a deposit, though you’ll need to make a small deposit before withdrawing any winnings from those spins. The Boku option is front and centre on the deposit page.

Bonus Boss is a bingo-focused brand that also carries a decent slot library. It accepts Boku with the same £10 cap as its siblings, and it occasionally runs promotions where a £5 Boku deposit unlocks extra bingo tickets. That’s a clever use of the payment method because bingo players tend to deposit in small, frequent amounts anyway.

Casino2020 is less flashy than its name suggests, but it does accept Boku for deposits. It’s part of the same InTouch network, so expect the same low limits and the same focus on mobile play. The game lobby is a bit dated, but the site is fully licensed and has a decent customer support record.

Slots Angel rounds out the list. This brand has moved between different operators over the years, but as of 2026 it still processes Boku payments for UK players. It’s a straightforward slots site with a small welcome package and a daily Boku cap of £10–£15. Nothing revolutionary, but it works.

Boku Casino Comparison Table

The table below summarises the key Boku deposit features for each brand we’ve verified. Remember that all these operators are deposit-only via Boku; withdrawals always go to a verified bank account or debit card.

Casino Brand	Bonus Type	Boku Deposit Limit	Withdrawal to Boku
mFortune	No deposit bonus + free spins	£10 per transaction	No
Mr Spin	No deposit free spins	£10 per transaction	No
PocketWin	Free spins on deposit	£10 per transaction	No
Dr Slot	No deposit bonus	£10 per transaction	No
Cashmo	No deposit free spins	£10 per transaction	No
Bonus Boss	Bingo tickets + free spins	£10 per transaction	No
Casino2020	Welcome bonus	£10 per transaction	No
Slots Angel	Welcome bonus + free spins	£10–£15 per transaction	No

Bear in mind that these limits apply specifically to Boku deposits. Some of these casinos will accept larger deposits via debit card or PayPal, but that defeats the purpose of using Boku. The daily cap across all casinos using the same mobile billing provider is often £30, so even if you visit five different sites, you can’t deposit £10 at each one every day without hitting a wall.

Pros and Cons of Boku Casinos

Let’s be blunt: Boku is not the best payment method for online gambling. It has a narrow use case, and that use case works for a specific type of player. Here’s the honest breakdown.

What works well: you don’t share card details with the casino, deposits are instant, and the whole flow is frictionless on a mobile. For a £5–£10 deposit, nothing beats tapping a confirmation code. It also enforces a natural spending limit because you can’t deposit more than your phone bill allows, which some players actually appreciate.

What doesn’t work: you can’t withdraw via Boku, which means every win eventually requires a separate payout method. The deposit caps are low, so it’s useless for serious bankrolls. Some networks charge a small fee for Boku gambling transactions, though this varies by provider. And because Boku deposits appear on your phone bill, they’re not exactly discreet if you share a bill with someone else.

Alternatives to Boku for UK Casino Players

If you’re reading this in 2026 and wondering whether Boku is still your best option, the answer is probably no—unless you specifically want to keep deposits tiny and phone-billed. For everyone else, there are better tools.

Debit cards remain the default for UK casino deposits. Visa and Mastercard debit cards work everywhere, process instantly, and allow withdrawals back to the same card in most cases. The Gambling Commission’s ban on credit card gambling means you can’t use a credit card, but a standard current account debit card is the most flexible option.

PayPal and other e-wallets like Skrill and Neteller give you a buffer between your bank and the casino. Withdrawals via e-wallets are often faster than bank transfers, and you can set your own spending limits on the e-wallet side. The trade-off is that some casino bonuses exclude e-wallet deposits, so check the terms.

Pay by bank app services like Trustly or open banking payments have grown a lot since 2023. They let you authorise a deposit directly from your bank app without entering card details, and they usually support both deposits and withdrawals. That’s essentially what Boku promised, minus the phone bill part and with higher limits.

Prepaid vouchers such as Paysafecard still work at a handful of UK casinos, but they’re deposit-only too. The advantage over Boku is that you can buy a voucher with cash and keep your gambling spend completely separate from any bank or phone account.

Is Boku Still Legal and Safe for UK Casino Deposits in 2026?

Yes, Boku is still a licensed payment service in the UK, and using it at a UKGC-licensed casino is legal. The Gambling Commission has tightened rules around affordability checks and deposit limits, but Boku deposits are not banned. However, the regulator’s guidance on “customer interaction” means casinos are supposed to monitor deposits made via phone billing just like any other method. Some casinos have chosen to drop Boku to reduce compliance overhead, which is one reason the list of Boku-accepting casinos has shrunk.

From a safety perspective, Boku is arguably safer than handing over card details because the transaction doesn’t expose your bank account. But that safety is one-way. If something goes wrong with a deposit—for example, you get charged twice or the casino doesn’t credit your account—the dispute process goes through your mobile network, not your bank. That can be slower and less consumer-friendly than a chargeback on a card. Keep that in mind.

Frequently Asked Questions About Boku Casinos

Can you withdraw winnings back to Boku?

No. Boku is a deposit-only payment method. Withdrawals must go to a verified UK bank account, debit card, or occasionally an e-wallet, depending on the casino. If a site advertises “Boku withdrawals,” it’s either misinformed or trying to mislead you. Always check the withdrawal page before you deposit.

What is the maximum Boku deposit at UK casinos?

Most UK mobile networks set a daily Boku spending cap of £30 for gambling transactions, though some allow up to £40. Individual casinos often set a lower per-transaction limit, usually £10–£15. The combined effect is that Boku is only suitable for small deposits. If you need to deposit £100, use a debit card or bank transfer instead.

Do all UK mobile networks support Boku casino deposits?

Not all. The major networks—EE, O2, Three, and Vodafone—generally support Boku payments for gambling, but smaller MVNOs may block them. Always check with your network if you’re unsure. Some pay-as-you-go plans also have different rules, and older contracts may need Boku enabled manually.

Why did some UK casinos stop accepting Boku?

Several operators dropped Boku after 2021 due to increased compliance requirements from the UK Gambling Commission and pressure from mobile networks concerned about problem gambling. Boku itself also tightened its merchant policies for high-risk categories like gambling. The result is that only a small group of mobile-focused casinos now offer Boku, and they tend to run on the same shared platform.

Are Boku casinos safe for UK players?

If the casino holds a valid UK Gambling Commission licence and you’re using Boku as intended—for small, occasional deposits—then yes, it’s safe. The payment method itself doesn’t change the casino’s core security or fairness. But remember that Boku deposits appear on your phone bill, and you still need to complete identity verification before withdrawing any winnings.

Can I claim a casino bonus with a Boku deposit?

Usually yes, but read the bonus terms carefully. Some casinos exclude Boku deposits from welcome offers or reduce the match percentage for e-wallet and phone-billed deposits. The brands in our table generally allow Boku deposits to count towards the welcome bonus, but they often require a minimum deposit of £10. Always check the specific promotion terms before you commit.

Final note: Boku isn’t dead, but it’s a niche tool. If you want tiny, phone-billed deposits at mobile-friendly casinos, the brands above still work. If you want bigger deposits, faster withdrawals, and a wider choice of games, use a debit card or an e-wallet. The “free” bonuses these casinos advertise are never free—they’re marketing costs designed to get you to deposit more. Play within your means, and never charge a gambling deposit to your phone bill unless you’re certain you can pay it when the bill arrives.
