Cricket Betting Markets
Cricket betting is not just about picking the match winner. bt3999 offers dozens of markets to bet on in every match. Some common betting markets are explained in simple terms below.
Match Winner
Example: Bangladesh vs India — if you bet on Bangladesh to win you get odds of 2.40.
Toss Winner
Example: Bet on which team will win the toss — odds for each team are generally about even.
Top Batsman
Example: Which batsman will score the most runs in an innings — pick the team's best batter.
Total Runs Over/Under
Example: Whether the team will score more than 170 runs in the first innings — consider the pitch and weather conditions.
Runs in an Over
Example: Whether more than 8 runs will be scored in the 15th over — this is the most popular market in live betting.
Man of the Match (Player of the Match)
Example: Which player will be named man of the match — all-rounders usually offer more attractive odds.
Method of Dismissal
Example: Whether the next wicket will be caught behind or bowled — LBW odds become attractive on spin-friendly pitches.
How do live in-play odds change?
Odds for the batting side increase with every wicket that falls. When a lot of runs are scored in an over, odds for the bowling side decrease. Odds fluctuate most during the powerplay, middle overs and death overs — so if you are live betting, make decisions based on how the match is unfolding.

How does a round work?
- Set your bet amount before the round begins.
- Once the plane (or rocket) takes off, the multiplier starts rising — from 1.00x to any value.
- You can press "Cash Out" at any time — your bet is multiplied by the multiplier at that moment.
- If you do not cash out before the crash, you lose your entire bet.
Auto Cash Out
Set a specific multiplier — when that value is reached, cash out will happen automatically. This is useful for avoiding mistakes made in a hurry.
Warning: Set a spending limit (stop limit) for yourself before you start playing. Any service claiming to provide "signals" or "predictions" is fraudulent.
RTP and House Edge Explained
What is RTP (Return to Player)?
RTP, or "Return to Player," is a statistic that shows how much money players get back on average per ৳100 wagered over the long run. For example, if a game's RTP is 96%, then on average ৳96 comes back for every ৳100 — the remaining ৳4 is the casino's revenue. Keep in mind that this calculation is based on hundreds of millions of rounds — your results in a single session can go either way.
Typical RTP ranges for different games
Slot games typically have an RTP ranging from 92% to 98%. Blackjack played with correct strategy can reach an RTP of close to 99%. For roulette, the European variant has an RTP of around 97.3%, while the American variant has a slightly lower RTP of around 94.7% due to its two zeros. In Baccarat, the "Banker" bet has a comparatively higher RTP.
What is House Edge?
House edge is the flip side of RTP — the percentage of total wagers that the casino retains. If RTP is 96%, the house edge is 4%. This is the foundation of the casino's business model. The house edge tells you which games favor the casino more and which favor it less.
Why does this matter?
Understanding RTP and house edge helps you make informed decisions. Choosing games with a higher RTP means your balance decreases relatively more slowly over the long run. However, all online games are designed to some extent in the casino's favor — RTP never guarantees a certain profit. Play for entertainment, not as a reliable source of income.
Quick RTP Comparison
| Game Type | Typical RTP |
|---|---|
| Blackjack | ~99% |
| European Roulette | ~97.3% |
| Baccarat | ~98.9% |
| Video Slots | 92–98% |
| American Roulette | ~94.7% |
* These are general industry ranges; verify the RTP of a specific game with its provider.
Betting Exchange
In a regular sportsbook, you bet against the casino. In a betting exchange, you bet against other players — the platform acts only as an intermediary.
Back vs Lay
When you Back, you are saying "this team/player will win." When you Lay, you are saying "this team/player will not win" — meaning you take on the role of the casino.
An Example (৳)
Say Bangladesh's Back odds are 2.00. You Back ৳1,000. If Bangladesh wins, you receive ৳2,000 (profit ৳1,000). If Bangladesh loses, you lose ৳1,000.
A player who has Laid Bangladesh has bet on Bangladesh losing — if Bangladesh loses, they receive ৳1,000.
Commission
The exchange platform takes a small commission from winning bets — that is how they earn. This is generally more favorable for the player than having odds directly reduced.
Back vs Lay Comparison
| Back Bet | Lay Bet | |
|---|---|---|
| You think | Team will win | Team will not win |
| You act as | Bettor | Bookmaker |
| If you win | Odds × Stake | Receive the stake |
| If you lose | Lose the stake | Must pay the liability |
| Risk | Limited to the stake | Comparatively higher |
We bring the safest, fastest, and most exciting sports betting experience for every cricket fan in Bangladesh.
