Football First: Premier League, Champions League, World Cup
Football is GSB’s flagship market by a clear margin, with coverage spanning the Premier League, Champions League, CAF Champions League, World Cup, Serie A, Ligue 1, La Liga, and MLS โ alongside dedicated football-specific promotions and the platform’s football-only cashout feature, which lets you lock in a result mid-match on the competitions that matter most to East African bettors.
GSB doesn’t offer full match live streaming, but its live tracker gives real-time statistics and match progress on in-play events โ enough to follow a game’s flow and time a cashout decision, even without video.
Basketball, Tennis and Combat Sports
Beyond football, basketball markets include the NBA, FIBA Finals, Euroleague and several regional leagues, the tennis section covers the full ATP and WTA tournament calendars, and combat sports โ UFC and boxing โ are well represented too. It’s a genuinely broad markets list for a bookmaker whose strongest coverage is still East African fixtures specifically.
Free2Win: Predicting the Calendar’s Biggest Events
GSB’s standout promotion is Free2Win, a prediction competition built around upcoming events: answer all 8 questions correctly and win up to a large prize, with smaller free-bet prizes for getting 4 to 7 right. It sits alongside a first-deposit welcome bonus, tiered free bets, and a refund bonus for accumulators that narrowly miss โ see our bonus hub for how Free2Win compares with other operators’ welcome offers.
Licensing, Mobile App and Getting Started
GSB holds a licence from the National Lotteries and Gaming Regulatory Board of Tanzania (licence number Sbl000000023, issued 14 August 2020) and has since extended into Uganda and Zambia under local authorisations in each. An Android app is downloadable directly from GSB’s website โ there’s currently no dedicated iOS app, so iPhone users bet through the mobile browser instead.
Registration follows the standard flow: sign up with a mobile number, verify, and make a first deposit to trigger the welcome offer under current terms. If you’re weighing GSB against other licensed operators, our full bookmaker guide breaks down the other options active across East Africa.
Deposits, Withdrawals and Payment Methods
GSB leans entirely on Tanzania’s mobile-money ecosystem rather than cards or bank wires. Supported methods are:
- M-Pesa (Vodacom)
- Airtel Money
- Mixx by Yas (formerly Tigo Pesa)
- HaloPesa
- Cash deposits at a GSB shop counter
Per GSB’s withdrawal help page, payouts run from a minimum of TZS 1,000 up to a maximum of TZS 3,000,000 per transaction. Withdrawals can be processed over USSD by dialling *148*53#, selecting Online Withdraw, entering the confirmation code sent by SMS, and checking for a final transaction SMS โ no separate app download is needed to cash out, and funds only move to the mobile number used at registration.
The welcome bonus has its own threshold, separate from general deposit limits: per GSB’s welcome bonus terms, the qualifying first deposit must fall between TZS 1,000 and TZS 1,000,000, and the bonus itself only unlocks once three qualifying bets worth at least that deposit amount have been placed.

- No full match live streaming โ only a live stats tracker for in-play events
- Cashout is limited to football markets only, so basketball/tennis/combat-sport bettors can’t lock in a result mid-event
