Cricket Betting Markets
During BPL and IPL, cricket betting at gbja is at its most exciting. Place in-play bets on Bangladesh Tigers matches and watch the odds shift with every wicket.
| Market | Example | Special Note |
|---|---|---|
| Match Winner | Bangladesh vs India — Bangladesh to win | The most common market, learn this one first |
| Toss Winner | Which team will win the toss | A simple 50/50 probability bet |
| Top Batsman | Who will score the most runs in this innings | Watch players who are in good form |
| Total Runs Over/Under | More or fewer than 160 runs in the first innings | Pitch and weather conditions matter |
| Runs in Over | Will the 15th over produce 8 or more runs | Make quick decisions in in-play |
| Method of Dismissal | Will the next wicket fall as a caught out | High odds, favoured by experienced bettors |
| Player of the Match | Who will be named player of the match | A chance to get the highest odds |
How in-play odds move
After each wicket falls, the odds for the weaker team to win increase. As each over ends, odds shift in line with the run rate. When betting live, quick decisions are essential — place your bet before the odds are locked.

How to Read Odds
Understanding odds before you start betting is very important. Knowing this helps you see how much profit a bet can return.
Decimal Odds Example
Say the odds on a match are 1.80 and you place a bet of ৳500.
Total return = ৳500 × 1.80 = ৳900
That means you get your original ৳500 back and make a profit of ৳400.
Implied Probability
1 ÷ odds × 100 = probability%. Example: 1 ÷ 1.80 × 100 ≈ 56% — the bookmaker thinks this team has a 56% chance of winning.
| Format | Example | Meaning |
|---|---|---|
| Decimal | 1.80 | ৳100 → ৳180 returned |
| Fractional | 4/5 | ৳4 profit on a ৳5 bet |
| American | -125 | ৳100 profit on a ৳125 bet |
RTP and House Edge Explained
RTP stands for Return to Player — it is the percentage of total wagers that a game returns to players over the long term. For example, if a slot game has an RTP of 96%, then theoretically ৳96 comes back for every ৳100 wagered over the long run — though results in any single session can be completely different.
House edge is the opposite of RTP. If RTP is 96%, the house edge is 4%. This varies by game type — slots typically range from 92–98%, blackjack with optimal strategy is around 99%, and roulette is generally 94–97%.
Understanding volatility or variance is also important. High-volatility games pay out big wins less frequently, but when they do come, the amount is large. Low-volatility games pay out smaller wins more often. Choose a game based on your budget and patience.
The purpose of knowing this information is so you can make informed decisions. RTP never guarantees a win — it is a statistical average based on billions of spins. Each round is independent and is not affected by previous results.
Typical RTP Ranges
| Slot Games | 92–98% |
| Blackjack | ~99% |
| Roulette | 94–97% |
| Baccarat | 98–99% |
Account Verification Process
KYC (Know Your Customer) or customer identity verification is an important part of online gaming platforms. It ensures security, prevents fraud, and restricts access for minors. Only individuals aged 21 or above can complete verification.
National ID Card (NID)
Upload clear photos of the front and back of your NID.
Proof of Address
Utility bill or bank statement (within the last 3 months).
Selfie Verification
Take a selfie holding your NID — your face must be clearly visible.
Processing Time
Verification is usually completed within 1–24 hours.
What happens after verification?
Once verification is complete, full withdrawal access will be activated on your account. For large withdrawal amounts, an additional verification request may be made — this is for your protection.
Bankroll Management Guide
The first step in responsible gaming is setting a clear budget. Decide in advance the maximum amount you can afford to lose and never exceed that limit. Treat your betting budget as a part of your monthly entertainment expenses — nothing more.
Instead of spending your entire budget in one session, divide it into smaller portions. For example, if your budget is ৳1,000, set aside ৳200–৳250 for each session. This lets you play longer, and one bad session cannot wipe out your entire budget.
Set 1–5% of your total bankroll for each individual bet. Say your session budget is ৳500 — then the maximum per bet is ৳25. This rule helps absorb the impact of variance and keeps you in the game over the long term.
After a win, there is a temptation to bet more. But smart players set a win target — for example, ending the session once they are up 50% from their starting bankroll. Similarly, set a loss limit — stop for the day if you lose 30% of your starting bankroll.
Keep a record of your play — how much you deposited, how much you won or lost, and what types of games you spent the most time on. This information will help you understand your own habits and make more informed decisions in the future.
Quick Tips
- Set your monthly budget in advance
- 1–5% of bankroll per bet
- Keep a win target and a loss limit
- Do not increase your bets on impulse
- Keep a record of your play
