Popular Betting Markets Overview
Cricket is the favourite sport among bettors in Bangladesh. Whether it's BPL or the T20 World Cup, every ball brings a new betting opportunity. See the common markets at a glance below.
| Market | Example |
|---|---|
| Match Winner | Bangladesh vs Pakistan — Bangladesh to win |
| Toss Winner | Tigers to win the toss |
| Top Batsman | Shakib to score the most runs |
| Total Runs Over/Under | More than 160 runs in the first innings |
| Runs in Over | More than 10 runs in the 15th over |
| Method of Dismissal | Next wicket to be bowled |
| Player of the Match | Mustafizur Rahman will receive the award |
Live In-Play Odds: Odds change instantly with every wicket or big run. Place your bet at the right moment — that's the excitement of in-play betting.
How Back & Lay Betting Works
In a regular sportsbook you bet directly against the platform. In a betting exchange you bet against other bettors — the market sets the odds, not the platform. The platform only takes a commission.
| Back | Lay |
|---|---|
| Bet in favour of an outcome | Bet against an outcome |
| If that team wins — you win | If that team loses — you win |
| Risk: the original stake amount | Risk: potential liability |
Example (in ৳)
Say the odds on Bangladesh winning are 2.0. You back ৳500. If it wins, you make ৳500 profit. If you lay ৳500 — and Bangladesh loses, you receive ৳500; if Bangladesh wins, you pay out ৳500.
Exchange commission is generally taken on net winnings; the platform will inform you of the exact rate. Better odds are often available on an exchange than at a sportsbook, because other bettors create the market.
Introduction to Aviator & Crash Games
A crash game is a fast-paced multiplier game where a plane (or another character) keeps flying and the multiplier keeps rising. The game can crash at any moment — you must cash out before that happens.
How to Play
- Place your bet before the round starts
- Watch the multiplier climb
- Cash out before the crash
- If it crashes, you lose your bet
Auto Cash Out
Set an auto cash out at a specific multiplier. For example, set it to 2x and you'll be cashed out automatically — no need to hold on driven by emotion.
Warning: Set a stop limit for yourself before you play. All crash games, including Spribe's Aviator, are powered by a random number generator — no "prediction" or "signal" is reliable.
