Cricket Betting Market Guide
Understand popular bet types and how in-play odds shift.
| Market | Example |
|---|---|
| Match Winner | Bangladesh vs India — bet on which team will win |
| Toss Winner | Bet on who will win the toss |
| Top Batsman | Who will score the most runs in the match |
| Total Runs Over/Under | Whether total runs in the full innings will be above or below a set number |
| Runs in an Over | Total runs scored in a specific over |
| Method of Dismissal | Next wicket — bowled, caught, run out, etc. |
| Player of the Match | Who will be named Man of the Match |
In live in-play betting, odds change quickly after each wicket and at the end of every over. When a team needs to chase a high total, the batting side's odds rise; when wickets fall, the bowling side's odds shorten. In-play markets give you the chance to analyze the situation as it unfolds.

Crash Game — Fast-paced Thrills
Understand fast multiplier games including Spribe Aviator.
In a crash game, each round starts with a plane (or rocket) taking off. The higher it climbs, the bigger the multiplier — but it can crash at any moment. Place your bet before the round starts, and cash out before it crashes.
Aviator (Spribe) is the most well-known crash game in Bangladesh. It includes an auto cash-out feature — you can set a target multiplier in advance.
Fast Rounds
Each round lasts just a few seconds to a few minutes. The environment is always fast-moving.
Set a Stop Limit
Decide on a maximum loss limit before you start playing — then stick to it.
⚠️ No "signals" or "predictions" work in crash games. Every round is random.

Baccarat
Bet on Player or Banker. A classic card game with some of the simplest rules. Table limits vary across different rooms.

What Is a Betting Exchange and How Does It Work
Bet against other players — not against the bookmaker.
In a regular sportsbook, you bet against the bookmaker. In an exchange, you bet against another player — the platform only acts as an intermediary and takes a small commission.
Back bet: You think something will happen — for example, Bangladesh will win. By backing, you are betting on it to happen.
Lay bet: You think something will not happen. By laying, you take the role of the bookmaker — if the other person wins, you pay out.
Example (in ৳): You Back ৳1,000 at odds of 2.0 — if you win, you receive ৳1,000. You Lay ৳1,000 at odds of 2.0 — if you lose, you pay ৳1,000 when the other person wins.
| Back Bet | Lay Bet |
|---|---|
| You win if the event happens | You win if the event does not happen |
| Like classic betting | Bookmaker's role |
| Limited liability | Liability based on odds |
| Odds from the market | You set the odds |
In an exchange, odds come from the demand and supply of players — the more participants in the market, the more competitive the odds.

Log In & Claim BonusBankroll Management Guide
Smart budget management makes your gaming experience last longer.
1. Set a Budget
Decide in advance the maximum amount you can spend on gaming each week or month. This amount should only be what you can afford to lose without affecting your daily life. Never use money meant for rent, food, or medical expenses to gamble.
2. Divide Into Sessions
Divide your total budget into smaller sessions. For example: if your weekly budget is ৳2,000, split it into four sessions — ৳500 each. This way, losing one session does not wipe out your entire budget.
3. The 1–5% Rule Per Bet
A single bet should never exceed 5% of your total session balance. Following this rule gives you more playing time and prevents your balance from running out quickly. The 1% rule is even more conservative and is ideal for long-term players.
4. Stop After a Win
After a good session, set a "win limit" in advance — for example, double the session balance. Once you reach that target, take a break. Placing more bets in the excitement of winning increases the risk of losing your earlier gains.
5. Take a Break After a Loss
If you have lost more than your session budget, stop for the day. Do not place more bets trying to "win back what you lost" — this is the most common mistake. Start a fresh session the next day with a clear head.
6. Track Your History
In a simple notebook or spreadsheet, record the deposit, bet amounts, and results of each session. Looking back after a month, you will understand which game, at what time, and at what stake level works best for you.
