How a Boku casino deposit works
Boku is a direct carrier billing provider: it charges purchases to your mobile bill or PAYG credit after an SMS confirmation. For casinos it historically meant deposits from £5 with a hard cap of £30 per day, deposit-only, no card details shared. The mechanics were excellent for budgeted play, which is exactly why it built such search demand.
A Boku casino is simply a UK online casino that lists Boku as a cashier option alongside cards and e-wallets, not a separate category of site. The games, licence and RTPs stay identical to any other payment route; only the funding and confirmation step changes. Because Boku is an integration an operator can switch off at any time, which sites still count as a Boku casino shifts from month to month rather than staying fixed.
Why Boku casino support is shrinking
After the Gambling Commission tightened affordability and source-of-funds requirements, carrier billing became the least transparent funding route an operator could offer, no bank statement trail, minimal customer data. Rather than build extra checks around it, most large operators removed Boku from the cashier entirely. The retreat has been gradual and quiet: sites rarely announce it, the option simply disappears.

Finding a Boku casino that still works in 2026
If you specifically want phone-bill deposits, the working UKGC-licensed routes are the ones on our main shortlist: Siru Mobile at the Videoslots platform sites (Videoslots, Mr Vegas, Mega Riches) and the PayviaPhone route, see our minimum deposit breakdown for how the fees stack up. The £3, no-fee in-house route some older guides still list belonged to In Touch Games (mFortune, PocketWin, Mr Spin, The Phone Casino); its UKGC licence was suspended and then surrendered in September 2023, and none of those brands are still trading. The user experience on the routes that do work is near-identical to Boku: amount, phone number, SMS confirm.
If a site you already play at lists Boku in its cashier, treat it as a bonus rather than a promise, and check the fee line on the confirmation SMS before approving, as surcharges vary by operator.
£5 Boku deposit: what it actually buys
- At the handful of cashiers still listing Boku, £5 is typically the lowest stake that clears the minimum threshold.
- It's confirmed the same way as any larger deposit: enter the amount, add a mobile number, approve the SMS prompt.
- A provider fee may be taken before the balance lands, so the amount credited can sit slightly under £5 depending on the operator.
- With the daily cap sitting around £30, a £5 deposit still leaves room for a few smaller top-ups later the same day.
- Welcome-offer eligibility on a £5 deposit varies by operator and often sits below the £10-£20 threshold many bonuses require.
Boku slots: what to expect
- Boku doesn't restrict which games are available; once the deposit clears, the balance behaves exactly like a card or e-wallet deposit.
- Slots typically make up the bulk of the game list at sites still accepting Boku, alongside a smaller table-games and live-dealer selection.
- Which titles you can actually play depends on the operator's own licence and content deals, not on Boku itself, so the game list still needs checking site by site.
- Wagering requirements and bonus terms attached to slots are set by the casino rather than by Boku, so the deposit method itself doesn't change what the offer terms say.
