Online casino features are constantly changing. For example, a new bonus may be better or worse. Based on this, the positions on our casino list change to reflect any significant improvements and failings at each casino. Also, when our users sign up and deposit at a casino on our list, we see that as very positive and boost that casino's rating accordingly.

How We Rate the Best Boku Casinos

We have some strict criteria for choosing the best Boku casinos. Boku casino sites must score points across the board to receive top marks. Any red flags get highlighted in all our online casino reviews. You can also use our casino review criteria to judge Boku casinos. Here are the main areas in which the best Boku casinos need to score highly:

Boku Casino Welcome Bonus

Many Boku casinos offer UK players a welcome bonus. But we’re looking for multiple deposit bonuses and plenty of free spins. High-percentage deposit bonuses are key. And we’re constantly weighing each of these things up with the wagering requirements. That’s because we believe you should be able to withdraw your deposit bonus and free spins winnings without grinding.

Boku Online Casino Games

It’s no good collecting a decent casino bonus if the games aren’t up to scratch. Therefore, we want Boku slot sites packed with table games, progressive jackpots and video poker. After all, playing casino games is the main reason for joining a Boku casino. We also ensure that all top game providers are present, including NetEnt, Microgaming, Playtech and more.

Boku Live Casino Games

Boku slot sites are ten a penny. But live casino games aren’t always available. Therefore, we take points away if there aren’t many live dealer games ready to fire up. On the flip side, we award bonus points if there’s a healthy selection of live games. Plus, Boku casinos with the full complement of Evolution Gaming titles will get a great score from us in this section.

Alternative Boku Payment Methods

While supporting the Boku casino payment method is a must for deposits, there needs to be a healthy selection of alternatives available, too. That’s because Boku withdrawals aren’t possible at pay-by-Boku casinos. So, we want to see bank account transfers, debit cards, e-wallets, and other options to get full marks. All of the top Boku casinos feature plenty of payment options.

Bokus Casino Customer Support

You never know when you might run into an issue. And it might happen outside of regular office hours. Therefore, all the best Boku casinos need round-the-clock customer support for UK players. Not only that, but each pay-by-Boku casino should offer a variety of contact methods. We’re discussing support via email, live chat and a UK phone number.

Mobile Boku Casinos UK

To get top marks, our reviewers need to consider a site as a Boku mobile casino. By this, we mean that it should be mobile-friendly or built with mobile phone users in mind. This can be done in one of two ways: either the Boku casino site is formatted for mobile customers, or there’s a dedicated casino app. For this, we test Boku casinos on many iOS and Android devices.

UK Boku Casino Licensing

All UK Boku casino sites should have a license from the UK Gambling Commission. The UKGC does a standup job of ensuring player safety. UKGC spot checks rigorously test every Boku casino in the UK, ensuring that the site is run by the book. Plus, the UKGC is firmly on the side of players. It will even resolve disputes between players and online casinos.

What is Boku, and What Are Boku Casinos?

Boku Inc. is an American company based in San Francisco. It's famous for enabling mobile phone users to use mobile billing to make Boku mobile payments. So, let's explore how the Boku payment system works. All Boku payments use the Premium Short Message Service (PSMS). This system was designed initially to enable people to buy ringtones via SMS text messages. Gradually, it was improved and expanded to enable the buying of music and games. This is where Boku Pay and online gambling come in.

The company behind Boku combined regular card payments with the PSMS system. Then, the team tweaked things to enable monthly mobile phone bill payments. And mobile payments for those on pay-as-you-go contracts. So, the need for cards, bank transfers, or other alternatives disappeared because of all the above, and new Boku casinos were launched in the UK. Now, you can find online casinos that accept Boku all over the UK.

Boku casinos are exactly what you think they are. They are online casinos that accept Boku payments.

Boku: Network-by-Network Guide for UK Players

Boku deposits work on every major UK carrier, but the user experience (and a few hidden catches) varies from one network to the next. The comparison table below shows what to expect for each provider: one-tap detection, built-in spending caps, and the most common roadblocks new players face.

Network Boku Available? Instant Number Detection Max Daily / Monthly Spend Things to Watch Out For
EE Yes – contracts & PAYG ✔ (single-tap if you’re on mobile data) £40 / £240 Some accounts launch with “Charge to Bill” disabled; ask EE support to lift the bar.
O2 Yes – “Charge to Mobile” £40 / £240 Always completes with an extra O2 page or SMS code – a built-in two-factor step.
Vodafone Yes – Add to Plan & PAYG £40 / £240 Brand-new contracts (under 3 months old) are barred from carrier billing until the trial period ends.
Three Yes – “3Pay” £40 / £240 Check the Spend Cap slider in the Three app – if it’s set to £0, Boku deposits will fail.

Why Play at Boku Online Casinos?

While you’ll need an alternative withdrawal payment method, Boku casino sites offer a great deal to UK players. They are safe and secure, and Boku deposits are extremely fast. They're also great for managing how much money you spend on Boku slots, table games and mobile casino games. By this stage, we hope that you have a much better understanding of how it all works and are encouraged to give it a go.

Pros and Cons of Boku Casinos UK

There are far more advantages to playing at Boku casino sites than negatives. But to give you a fuller picture, we've collected the main upsides and downsides. In this way, you can decide whether or not you want to find the best Boku casinos. Here are the main pros and cons:

Pros

  • Boku casinos are widely available in the UK
  • No set-up is required – just a mobile number
  • Boku deposits are processed almost instantly

Cons

  • You have to add credit beforehand if using pay as you go
  • Deposit limits of £30 per day per mobile phone number
  • Online gambling withdrawals are not possible with Boku

How To Deposit at a Boku Casino

Here, we’ll discuss depositing money into your casino account using Boku. As we mentioned, Boku makes pay-by-phone-bill transactions dead easy. Here’s what you do:

  1. Sign up at one of our recommended online gambling sites that accept Boku
  2. Head to the cashier via the ‘Deposit’ button and select Boku or pay by phone
  3. Enter your mobile phone number and deposit amount in the Boku interface
  4. Reply with ‘Y’ (‘yes’) to the Boku SMS text message to confirm the transaction
  5. Your Boku deposit will be available immediately and charged to your phone bill

Expert Tips for Using Boku

Hands-on test by Chris Vaughan, Senior Writer at GamblingAuthority:

Chris’ verdict: “Boku is still the fastest way to load a small bankroll, but have an e-wallet ready for payouts.”

Boku Casino Deposit Limits

You can use Boku with a monthly mobile phone contract or pay-as-you-go. However, because it is a form of credit, in some cases, there is a deposit limit. This deposit limit is usually £30 per day per mobile phone number. Once that deposit limit is reached, you must wait 24 hours to make further Boku deposits. Still, this restriction helps players manage how much they are spending at a Boku casino UK. Therefore, we think this is a good thing. As for the minimum deposit at most Boku deposit casinos, that is usually around the £10 mark.

Boku Casino Deposit Fees

You will not usually be charged any fees for a Boku casino deposit. We usually say that because Boku does not charge fees for a Boku payment. However, some pay-by-Boku casino sites might charge minimal fees. But with plenty of Boku casino choices, we would avoid those that charge fees. After all, the instant casino deposits Boku players make are below £30, so fees would be a real kick in the teeth for many. The good news is that most Boku payment casino sites do not charge anything to make casino deposits.

Using Boku via Neteller (Work-around)

Direct Boku deposits have become rarer at newer UK casinos, compared to newer options like Siru, but you can still fund your play indirectly with a simple two-step workaround:

  1. Top-up your Neteller wallet with Boku. Open the Neteller app or website, choose Pay by Mobile (Boku) as the funding method, enter the amount (up to £30) and confirm the SMS. The money is instantly added to your Neteller balance.
  2. Deposit from Neteller to the casino. Head to the casino cashier, pick Neteller, log in to your wallet and complete the usual e-wallet transfer. Your gaming account is credited right away, and withdrawals can be sent back to the same wallet.

This route keeps the convenience of Boku’s pay-by-phone billing while giving you full cash-out capability through Neteller. For a complete rundown of fees, limits and bonus eligibility, see our dedicated guide to Neteller casinos.

Online casino bonuses are plentiful at the best Boku casino sites. From the initial welcome bonus and free spins to other deposit bonus offers later. Here, we’ll go over the main Boku casino bonuses you’re likely to find at UK sites:

Boku Casino Welcome Bonuses

The welcome bonus is often the most significant deposit bonus, with free spins. All of the best Boku casinos offer some form of welcome bonus deal. Usually, this consists of one or more deposit bonus deals in a row. And thrown in on top, you can expect plenty of free spins and casino bonus spins. Just note that the free spins will normally be given out over several days. For more info, check out our list of top welcome bonus casinos in the UK.

Boku Casino Free Spins

Casino free spins promotions are abundant at Boku slot sites. Free spins are limited to one or two games when tied into a welcome bonus. These are often popular Boku slots like Book of Dead, Gonzo's Quest or Starburst. Later on, you will receive free spins for the latest releases. Or else you'll be given regular free spins on a specific day each week. Just check the wagering requirements. You won’t be able to withdraw your free spins winnings without completing the wagering.

Boku No Deposit Bonuses

Getting a no deposit bonus is a dream for many UK casino players. As its name suggests, you do not need to make a minimum deposit to claim a no deposit bonus. This makes it a no-brainer Boku casino bonus for many. UK casino no deposit bonuses can consist of small playing funds – say £10 or £20. Or they can be a fistful of free spins instead. Again, check the wagering requirements beforehand so you can withdraw your winnings.

Boku Casino Cashback Bonuses

Some Boku casino sites like to do things differently. This is particularly the case with VIP Boku casinos. High rollers often aren’t all that interested in free spins. Instead, they want a casino bonus that can aid them in case of a bad run. That’s where the casino cashback bonus comes in. Players can receive bonus money for a certain amount of losses each week. So, if you're playing at casinos that accept Boku payments, check for cashback bonuses.

How To Withdraw From a Casino with Boku

As mentioned above, you cannot make Boku withdrawals. The system doesn’t work in that way. Therefore, you’ll need an alternative payment method to withdraw your winnings. But don’t worry, GamblingAuthority has your back. A little further down the page, we cover all the alternative payment methods you can use to make casino withdrawals. We detail the whole process if you're looking for more info about fast withdrawal casinos. You can use that guide to select the best payment methods and quickly withdraw.

How To Sign Up for Boku

You do not need to sign up for a Boku account. Instead, the payment service works on any UK mobile phone. All players have to do is enter their phone number at a Boku deposit casino. Then, they confirm the payment by receiving an SMS from Boku. It's that simple!

Boku Casinos: Safety and Security

When joining a pay-by-Boku casino in the UK, you can rest assured about safety and security. Of course, you will still need to consider a few security factors – more on this below.

However, your payment method and financial data should be safe. You only share your phone number with the casino when depositing. So, ensure you choose a secure withdrawal payment method, and you’ll be golden.

So, when claiming a Boku mobile casino bonus or an alternative Boku offer, you don’t have too much to worry about. However, we have some extra advice below to ensure your online safety. Follow our two main rules below to concentrate on playing games.

Boku Security and Data Protection

As mentioned above, Boku is a very safe and secure payment method. You share your phone number and pay for your deposits via your phone bill. However, you still need to follow online safety best practices. This includes picking a strong password with letters, numbers, and special characters. Furthermore, you can enable two-factor authentication when logging in. You must enter a verification code or use Touch ID or Face ID.

UK Gambling Commission License

The UKGC licenses every online casino we recommend. This ensures the casino is in the United Kingdom and adheres to its rules. These rules cover everything from how a site stores player data and funds to responsible gambling and marketing practices. In addition, the UKGC often steps in to resolve any issues between online casinos and UK players. In short, the UKGC offers the best protection for UK players.

3 Alternatives to Boku Casinos

While you can find casino sites that accept Boku everywhere, you’ll need another withdrawal payment method. Or, if you’re not quite convinced about playing at a Boku deposit casino, let’s review your options. Here are the main alternatives to making a Boku payment:

3 Alternatives to Boku Casinos

While Boku is the best-known pay-by-phone option, it isn’t the only one. Below are the three main substitutes you’ll see at UK-licensed sites, including Payforit and newer carrier-billing brands such as Fonix.

1. Payforit – the direct Boku rival

Payforit works almost identically to Boku: you authorise a deposit by replying to a free SMS and the charge appears on your mobile bill (or is deducted from PAYG credit). The same £30 daily cap applies, and withdrawals still need a bank transfer or e-wallet.

2. Apple Pay & Google Pay – wallet-based mobile payments

Both services let you fund your casino account instantly with the debit cards saved in your phone’s wallet. Unlike Boku or Payforit, they Apple Pay and Google Pay support withdrawals at many UK sites once you verify the card on file.

3. Debit Card Payments: still the default

Visa and Mastercard remain the simplest all-round option: unlimited deposit ceilings, full cash-out support and universal acceptance. If carrier billing limits feel restrictive, switching to a debit card casino option—or an e-wallet topped up via Fonix, Payforit or Boku—is the quickest way to scale up. The only downside is that alternative payment methods are not as secure. Also, credit cards cannot be used at UKGC-licensed online casinos.

Other emerging carrier-billing providers: Fonix and Phonepe use the same direct-carrier-billing (DCB) rails as Boku and Payforit, but are still rolling out across UK casinos. Keep an eye on our payment-method hub for updates as more operators add these brands.

How Boku Pay by Mobile Stacks Up Against Other Deposit Options

Payment Method Type Deposits Withdrawals Daily Limit Need a separate account?
Boku Direct carrier billing (SMS) Instant – charged to phone bill Not supported £30 per mobile number No – just a UK mobile number
Payforit Carrier billing (SMS) Instant – charged to phone bill Not supported £30 per mobile number No – UK mobile number only
Debit Card Bank card (Visa/Mastercard) Instant 1–3 banking days Set by casino / card issuer Yes – bank account required
E-wallet (e.g. Neteller) Digital wallet Instant Same-day or under 24 h Usually no fixed limit† Yes – wallet account required

†Any overall limit will depend on your e-wallet verification level and the casino’s own cashier cap.

Boku Casino Conclusion

UK players will find plenty of new Boku casinos and more established ones. The phone bill payment method is incredibly popular in the United Kingdom. Plus, unlike some eWallets, Boku deposits enable players to claim a welcome bonus and free spins. On top of that, using Boku is fast, secure and straightforward. While the £30 deposit limit per day will be seen as a downside, we think it's advantageous for some UK players as it enables them to manage their gambling budget more successfully. Check out the best Boku casinos above and read our online casino reviews for more info. Then, start paying by phone bill with Boku.

Boku Casino FAQs

A Boku Pay by Mobile casino is an online gambling site that lets you fund your account by charging the deposit to your UK mobile-phone bill instead of using cards or e-wallets.

Boku is one of the most secure payment methods for UK online casinos. That's because you don't need to enter card details – you only share your phone number. Plus, if the UKGC licenses the site in question, you'll be in safe hands. Please read our reviews for more info.

No – Boku is a deposit-only service, so you must choose an alternative method (bank transfer or e-wallet) when you cash out.

Absolutely! Boku pay-by-phone casinos are immensely popular in the United Kingdom. And if you only ever play at Boku casinos licensed by the UKGC, you won't encounter any problems. Just practice good online safety like two-factor authentication and you'll be safe as houses.

Boku casino sites stock the same games as regular online casino sites. Pay by mobile slots players enjoy how easy Boku deposits are. So, you'll find hundreds of top-notch slots (as well as plenty of free spins). These are in addition to table games, bingo, poker and more. Some of the best Boku sites even offer sports betting, too.

Boku itself charges zero fees to UK players, although a few casinos may add a small processing fee, so always check the cashier page.

Boku deposits are instant once you confirm the SMS, meaning the funds appear in your casino balance within seconds.

The standard Boku cap is £30 per mobile number per 24 hours, which helps players keep spending under control.

Yes – Boku works with every major UK carrier (EE, O2, Vodafone and Three) on both contract and pay-as-you-go plans.

No – because of the £30 daily ceiling, Boku is designed for low-stakes players; high-rollers should use debit cards, instant bank transfer or an e-wallet instead.
