gb99 Bet — The Complete Sports and Casino Betting Process in One Place
Knowing each step clearly — from login to bet settlement — makes betting much easier. This page covers every step at gb99 Bet in detail — choosing markets, reading odds, filling in the bet slip, and checking bet history.
Log in and add funds to your account
To start betting at gb99 Bet, first go to the gb99 login page and enter your username and password to access your account. Once logged in, go to the deposit option from the dashboard.
For deposits at gb99, you can use bKash, Nagad, Rocket, Upay and bank transfer. The minimum deposit amount is ৳100. Select a payment method, enter the amount, complete the payment as instructed — the balance will be added to your account within a few minutes.
Once the deposit is done, you can go directly to sports betting or casino — whichever section you prefer. A 100% bonus is available on the first deposit — depositing ৳1,000 adds ৳1,000 in bonus, bringing the total balance to ৳2,000, and a 20x wagering requirement applies on the bonus (meaning you need to place ৳1,000 × 20 = ৳20,000 in bets before withdrawing the bonus).

Find markets and learn to read odds
When you enter the sports section of gb99 Bet, you will see various sports and events. Choose a match in cricket, football or any other sport and go to the market list. There you will find various markets including match winner, total runs and handicap. Each market has odds assigned to it.
Odds are generally shown in three formats: decimal, fractional and American. The decimal format is most commonly used at gb99. See a comparison example below:
Example 1 — Team A to win, stake ৳1,000
If the bet wins, you get back ৳2,250 (profit ৳1,250 + original stake ৳1,000). If the bet loses, ৳1,000 is gone.
Example 2 — Team B (favourite), stake ৳1,000
If the bet wins, you get back ৳1,800 (profit ৳800). American minus odds mean you need a stake of 125 to make a profit of 100.
You can read more about cricket betting on the gb99 cricket betting page — it has separate discussion on BPL, IPL and T20 World Cup markets.
Example 3 — Cricket match winner (limited overs, no draw)
If you bet ৳1,000 on Team B and Team B wins, you get back ৳1,750 (profit ৳750). If Team A wins, ৳1,000 is lost.
Example 5 — Betting exchange, Team A, decimal 1.80
BACK: A ৳500 bet wins ৳400 profit if Team A wins (before commission); if they don't win, ৳500 is lost.
LAY: The lay liability against a ৳500 bet is ৳400 (৳500 × 0.80).
If Team A does not win, the layer receives ৳500; if Team A wins, the layer must pay ৳400.
Bet slip — rules for placing single and multi bets
Clicking on any odds adds it to the bet slip. If one selection is in the slip, it is a single bet. Enter the stake and the potential return is shown immediately.
Adding multiple selections to the slip creates a multi bet. In a multi bet, the odds of all selections are multiplied together, so the return can be much higher — however, if any one selection loses, the entire bet is lost.
Example 4 — Multi bet with 3 selections, stake ৳100
Combined odds = 1.40 × 1.60 × 1.70 = 3.81 (rounded).
If all three selections win, you get back ৳381.
If even one loses, the full ৳100 is gone.
Before confirming a bet, check the stake and potential return once. You can also remove unwanted selections from the slip.
Sports and casino betting — how the two sections work
Sports Betting
In the sports section of gb99 Bet, you can bet on cricket, football and other sports events. In addition to pre-match bets, live in-play markets are also available, where odds change as the match progresses. Betting markets are available for BPL, IPL, T20 World Cup and Bangladesh Tigers international matches. Visit the gb99 cricket betting section for more details on this.
Casino Betting
In the casino section of gb99 Bet, you can bet on slots, live casino and table games. Each slot has its own RTP and paylines; in the live casino you can play baccarat, roulette and other games with real dealers. To see the full list of casino games, go to the gb99 Casino page.
View open and settled bets in bet history
At gb99 Bet, the record of every bet is stored in the Bet History section of your account. This is usually found under the account menu or the "My Bets" option.
Checking bet history regularly gives a clear picture of how much has been spent and how much has been won. It also helps with setting a budget.
Set a budget and limits before you start betting
Betting is a form of entertainment — not a way to earn income. So set a weekly or monthly budget for yourself from the start. Stay firm in your decision not to deposit more than that amount.
gb99 Bet encourages betting in line with the responsible gaming guidelines. Account settings include the option to set deposit limits, betting limits and session time limits.
Keep in mind
Betting is primarily entertainment. No betting method or strategy guarantees profit over the long term. If the chance of losing outweighs the chance of winning, it is wiser to step away from that bet.
For all rules and terms related to betting, read the details on the terms and conditions page.
