Frequently asked questions

What is GSB in Tanzania?
GSB stands for Gal Sport Betting, a sports betting and casino brand available in Tanzania. You can use the GSB website, Android app or mobile site to bet on the English Premier League plus Tanzania's NBC Premier League and the Simba–Yanga derby, and to play casino, slots, Aviator and jackpots via mobile money.
How do I register at GSB Tanzania?
To register, open the GSB registration page, enter your Tanzanian phone number, confirm the SMS/OTP code, and set a password. You must be 18+ and use one account in your own name. Verifying your identity later (for example NIDA details) enables withdrawals. See our registration and verification guides for the full steps.
How do I log in to GSB TZ?
Open the GSB site or app and sign in with the Tanzanian phone number and password you used to register. If you forget the password, tap the reset option and follow the SMS sent to your registered number. If the reset SMS does not arrive, contact GSB customer service.
How do I place a bet at GSB?
To place a bet (weka dau), log in and deposit from 100 TSH, then open a sport and pick a match. Choose a market like 1X2 or over/under, tap the odds to add it to your slip, enter your stake in TSH, and confirm. This guide does not tell you what to bet — see our sports-betting and odds guides.
What is the GSB welcome bonus?
New players can claim a 100% bonus (bonasi) on their first deposit, up to 1,000,000 TSH. The exact percentage and any promo code depend on the current promotion, and the bonus carries a wagering requirement before winnings can be withdrawn — always read the terms first. See our bonus guide for the wagering details.
What is the minimum deposit at GSB Tanzania?
You can deposit (kuweka pesa) from 100 TSH using Vodacom M-Pesa, Airtel Money, Tigo Pesa (now Mixx by Yas) or Halotel (HaloPesa). On the deposit page, choose your provider, enter your number and amount, then approve the mobile-money request or USSD prompt with your PIN. Top-ups are usually instant. See our minimum-deposit guide.
How long do GSB withdrawals take?
Withdrawals (kutoa pesa) to mobile money usually clear within 1 to 24 hours, in East Africa Time (EAT / UTC+3). Your account normally needs to be verified first — confirming your identity (for example NIDA details) and a mobile-money number in your own name — or the payout can be blocked. See our withdrawals guide for limits.
Is GSB betting available on mobile?
Yes. On Android, install the GSB app from Google Play where it's listed, or download the APK from the official GSB site and allow your browser or file manager to install it. There is no separate iPhone app, so iOS users open the optimised mobile site and can add it to the home screen. See our app guide.
How do I check if my GSB bet won?
To see whether a bet won, lost or was voided, open My Bets or the results section for the match outcome. To confirm a bet was actually accepted and is pending, use ticket check with your bet ID or slip number — a booking code only reloads an unplaced selection you must still stake. See our results and ticket-check guides.
Does GSB have Aviator?
Yes. GSB offers the Aviator crash game alongside slots, live casino and jackpots. Each Aviator round is independent and random, so there is no way to know the next result — set a cash-out target and a budget before you play, and stop when you reach it. See our Aviator guide.
Is GSB betting legal in Tanzania?
Betting in Tanzania is overseen by the Gaming Board of Tanzania (GBT) and is limited to adults aged 18 and over. This independent guide does not verify any operator's licence or registration numbers — check GSB's current licence status on GSB itself. Bet responsibly: set deposit or time limits, take breaks, and use self-exclusion if betting stops being fun.
How do I contact GSB customer service?
For account, login, deposit, verification or withdrawal problems, use GSB's official support channels — typically live chat, email and the on-site help or FAQ section. Have your registered GSB phone number or bet ID ready so support can find your account. See our customer service guide for the current contact options.
Is this the official GSB website?
No — this is an independent guide to GSB (Gal Sport Betting) for players in Tanzania, not the operator. Always open your account and confirm the current bonus terms, payment limits and the correct GSB domain on GSB itself before you deposit or bet. We do not take bets or hold funds.
