The advantages and disadvantages of using Boku
Pros
- No need for a separate account or app: Unlike other payment methods such as PayPal or standard e-wallets, a pay by Boku casino allows you to make deposits which are then either charged to your mobile phone bill or deducted from your pre-paid balance. There’s absolutely no need to set up or maintain a separate account – this makes your online gaming funds that much easier to manage.
- Use Boku on any mobile phone: Although a significant proportion of the UK population owns a smartphone, you don’t need the latest tech in order to play at a Boku casino or bingo site. You can make a Boku payment on any device that can send and receive text messages — even on the earliest mobile phones.
- A secure payment method: Many players prefer playing at a Boku mobile casino because of the additional security it provides in relation to personal and financial information. Because your Boku payment is charged to your phone bill, you don’t need to share debit card details with either the casino or a third party service provider. Likewise, your details aren’t stored anywhere so you are less susceptible to hacking, fraud and identity theft.
- No fees from Boku or your network: The Boku service itself is free to use, and your mobile network won’t add a separate charge for using it. The amount you deposit is the amount that shows up on your phone bill, or that comes off your pre-pay credit. The catch sits on the casino side. Some operators pass on a fee for offering Boku as a deposit method, so always check the cashier page before you commit.
- Simple to use: making a Boku casino deposit is a straightforward process. You simply access the banking or cashier page and follow the instructions as you would with any other payment method.The only discernible difference is that you’ll need to have your mobile phone handy to receive a confirmation text message.
Cons
- Withdrawal not available with Boku: with Boku, pay by mobile casino sites that accept the service require you to cash out with another provider. If you don’t have another method that you can use, you’ll need to nominate an alternative withdrawal method (usually debit card or e-wallet).
- Deposits are limited: You will generally be limited both in the size of individual transactions and the total amount you can add to your account in a day when you make a Boku casino deposit. The standard cap is £30 per transaction, with most UK networks allowing up to around £90 per day across all merchants. For casual and occasional players, this probably doesn’t present much of a problem. For experienced, high-rollers however, these limits may prove a bit off-putting.
- Some casinos charge a Boku fee: This is the one to watch. Most UKGC-licensed casinos don’t charge anything for a Boku deposit, but a handful do. Where the fee exists, it can be steep, with some operators applying up to 15%. On a £15 deposit at a 15% site, that’s £2.25 gone before you’ve placed a bet. If you plan to use Boku regularly, pick a site that charges nothing rather than absorbing a recurring cost.
How to Deposit and Bank With Boku at Online Casinos
So what precisely does the process of making a Boku casino deposit entail? And what are some of the things you should keep in mind before signing on the dotted line? Let’s find out.
Banking with Boku
First of all, you need to weigh up all the pros and cons if you are thinking about signing up to play at a Boku casino. And while there are growing numbers of casino sites and Boku bingo platforms, you really need to consider whether this is the right payment method for you.
Deposit and withdrawal times
One thing you can be sure of when you pay at a Boku-friendly casino is that your funds will be credited to your account and can be accessed straight away. There is no processing time, so you can start gambling immediately. However, as you can’t withdraw using Boku, you need to find an alternative method when you want to cash out. We recommend PayPal, or an e-wallet like Neteller or Skrill – these offer the fastest payout times although keep in mind that there will usually be a processing time of at least 48 hours at almost all online casinos before payments are completed. See our PayPal casinos page if you’re interested in using this option.
Ease of opening an account
There is no separate Boku account to set up or manage. As long as you have a mobile phone and are playing at a casino with Boku, there is not much else you need to do. When you select Boku as your payment method on the banking or cashier page and enter the amount you want to deposit, you’ll be prompted to enter your mobile phone number. You’ll then receive a text message, asking you to confirm the payment amount. Once this is done, your funds become available.
Fees structure
There are three layers worth understanding. Your mobile network won’t charge you a fee for using Boku. The amount you deposit is the amount that lands on your phone bill, or that comes off your pre-pay balance. Boku itself doesn’t charge the player either, since it earns its money from the casino. The fee question is really about the casino. Most UKGC-licensed sites pass nothing on, but some do, and the percentage varies. We’ve seen anything from a small handling charge up to 15% at the higher end. Check the banking or cashier page before you deposit. The fee, if there is one, will be listed alongside the Boku option.
How to Use Boku at Online Casinos
If you’re wondering how to deposit by Boku at your chosen pay by mobile casino, slots or bingo operators, the following step-by-step guide should help.

Step 1: Select a Boku Pay By Mobile iGaming Site
Find an online casino, slots or bingo site that supports Boku. You’ll find it in the cashier or payment methods section. Then register or log into your account.

Step 2: Choose the Boku Mobile Payment Option
Once registered or logged in, visit the cashier section and select the Boku payment icon.

Step 3: Enter Your Deposit
Choose your Boku deposit amount and provide your mobile phone number.

Step 4: Confirm Your Deposit Via Mobile
Once you’ve entered your phone number correctly, you’ll receive a confirmation text. Reply by typing Yes or via a code in order to authorise your Boku pay by mobile payment.

Step 5: Check Your Casino Balance
As soon as your Boku casino payment has been approved, the funds will be immediately credited to your account.
Is Boku Safe and Secure for Online Casino Payments?
Boku is a safe and secure way of making online casino payments, and it’s increasingly available across new casino sites in the UK. With Boku, you don’t need to provide any bank details which means that there’s no need to share sensitive financial or personal information. All you need is an active mobile phone number, be it via contract or through a pre-paid option.
Secure online casino payments with Boku are also secured with two-factor authentication. In other words, once you’ve made a Boku payment, you’ll receive a confirmation request via text that you must reply to in order to authorise the transaction. Robust data encryption protocols are also in place which effectively add an extra layer of security.
Who Should Use Boku at Casinos?
Boku is tailor-made for mobile users due to its secure and easy-to-use mobile casino deposit process. However, given the deposit limits in place and the fees that are applied to most online casino sites, it’s the kind of pay-by-mobile option that is perhaps better suited to casual gamers who don’t enjoy sharing their bank details.
If that sounds like you, it’s also worth knowing that there are bingo and casino sites out there where you can get started with just a £5 deposit using other payment methods. Our guide to 5 pound casino sites is a good place to start if you want to keep your spend nice and low.
Other Casino Payment Methods to Compare with Boku
Final Thoughts: Is Boku the Best Mobile Payment Method for Casinos?
In terms of simplicity and convenience, there’s much to like about Boku. The process of making a deposit is very easy — just reply to a text message to confirm your deposit and the amount requested. It is also a simple and straightforward payment method in that there is:
- no new account to set up and maintain
- no new passwords to remember
- no new app to download and install
However, there are also some drawbacks, not least the fact that the number of Boku casino and bingo sites and online casinos accessible by UK players is still relatively limited. If this is your preferred payment method, you won’t have as many playing options as you might otherwise enjoy with alternative services. The limit on deposits is also a negative factor, as is the fact that the Boku casino payment option can’t be used to cash out and make withdrawals. In this regard, we highly recommend that you use the Paypal method mentioned above.
Worth flagging too: a small number of casinos add their own fee on top of Boku deposits, sometimes as much as 15%. Most don’t, but it’s always worth a quick look at the cashier page before you deposit.
On the whole, our view is that the Boku payment option is a good option for someone who plays at online casinos, slots and bingo sites every now and then, and neither invests nor expects to win too much. However, if you are a more serious, dedicated player, other payment methods will likely suit you better. Check out expert picks for best casino sites.
BOKU Casinos Commonly asked questions
FAQS
Can I withdraw my winnings using Boku?
No. Boku is a deposit-only payment method at UK casinos. When you’re ready to cash out, you’ll need to nominate an alternative, usually a debit card or an e-wallet like PayPal, Skrill or Neteller. It’s worth setting up your withdrawal method when you first register, so it’s ready to go when you need it rather than slowing down a payout.
Will I be charged a fee for using Boku at a casino?
Boku doesn’t charge you, and your mobile network doesn’t either. Any fee comes from the casino itself. Most UKGC-licensed sites pass nothing on, but a small number do, with some applying up to 15%. Always check the banking page of the site you’re using before you deposit so you know exactly what, if anything, you’ll be charged on top of your deposit amount.
How much can I deposit with Boku in a day?
The standard cap is £30 per transaction. Most UK networks allow up to around £90 per day across all merchants and roughly £240 to £300 per month, with EE, O2, Vodafone and Three all working to similar ceilings. Some casinos enforce a lower per-deposit limit on top of that. If you regularly deposit larger amounts, a debit card or e-wallet will give you more headroom.
Can I claim a welcome bonus when I deposit with Boku?
Usually, yes. Unlike Skrill and Neteller, which are commonly excluded from welcome offers, Boku is generally treated like a debit card for bonus eligibility. That said, some of the bigger welcome packages do exclude mobile billing, so always check the bonus terms before you deposit. If the T&Cs list excluded payment methods, look for “Boku” or “pay by mobile” in the small print.
Which UK mobile networks support Boku?
All four major UK networks support Boku for casino deposits: EE, O2, Vodafone and Three. Most of the larger virtual networks running on those host networks are covered too, including BT Mobile, Tesco Mobile and Sky Mobile, though support on smaller MVNOs like giffgaff can be patchy from one casino to the next. If your network isn’t supported, the cashier will reject the deposit at the SMS confirmation step.
