Cricket Format Explained
T20, ODI, Test and The Hundred — Understand the Differences
Before betting on different cricket formats, it is important to know the features of each format.
20 overs per team, matches usually finish in 3 to 3.5 hours. In-play betting, session betting and bowler-based markets are the most popular. BPL and IPL are held in this format.
50 overs per team, matches usually finish in 7 to 8 hours. The ICC World Cup and Asia Cup are held in this format. Various partnership and total-runs markets are available.
A 5-day match with unlimited overs per innings. Long-term markets such as match winner, draw or innings margin are the most interesting.
100 balls per team, the shortest format. Popular in England. BBL (Big Bash) and PSL (Pakistan Super League) are also held in the T20 format.

Aviator and Crash Games — Fast Rounds, Intense Excitement
A crash game is a fast-paced multiplier game where a plane or rocket climbs steadily and the multiplier keeps rising. You can cash out at any time — but you must get out before the crash, or you will lose your entire bet.
Aviator by Spribe is one of the most popular crash games in the world. Each round ends in just a few seconds to minutes. With the auto cash-out feature, you can exit automatically at a set multiplier.
Set a stop limit before you start playing and try not to stay in too long out of greed. Do not trust any tool that claims to predict or signal outcomes — every round is completely random.
How Does Auto Cash-Out Work?
1. Place your bet before the round starts
2. Set your multiplier target (for example 2.0x)
3. When the plane reaches that multiplier, you will cash out automatically
4. If you get out before the crash, you win

Betting Exchange
Back and Lay — Understanding Exchange Betting
In a regular sportsbook you always bet against the bookmaker. In an exchange you bet against other players — the bookmaker simply takes a small commission in the middle.
A Back bet means you think something will happen (e.g. Bangladesh will win). A Lay bet means you think something will not happen (e.g. Bangladesh will not win).
Example: Bangladesh vs India T20
Back: You place ৳500 on Bangladesh to win at odds of 2.5. If Bangladesh wins you receive ৳1,250 (profit ৳750).
Lay: You place ৳500 on Bangladesh not to win at the same odds. If Bangladesh loses you receive ৳500 (profit). If they win you pay ৳750.
Back vs Lay Comparison
| Category | Back Bet | Lay Bet |
|---|---|---|
| Meaning | Betting that something will happen | Betting that something will not happen |
| Risk | Stake amount | Higher, depending on odds |
| Who can do it? | Anyone | Exchange only |
| Commission | Small cut on winnings | Small cut on winnings |
| Who sets the odds? | Other players | Other players |
It is possible to get better odds on an exchange than on a regular sportsbook because the margin is lower.

RTP and House Edge Explained
RTP and House Edge — Know Before You Play
RTP (Return to Player) is a percentage that shows how much of the total amount wagered a game returns to players over the long term. For example, if a slot game has an RTP of 96%, it theoretically returns an average of ৳96 for every ৳100 wagered. However, this is an average across millions of spins — results in a single session can vary greatly from this figure.
House edge is the flip side of RTP. If a game has an RTP of 97%, the house edge is 3%. This 3% is the game provider's earnings — it is what keeps the platform running.
Learn the typical RTP range for different game types:
Typically 92%–98% RTP. High-volatility slots can deliver big wins but losses are also higher.
Around 99% RTP with the right strategy. The lowest house edge — a favourite among skilled players.
Around 97% RTP on European Roulette. American Roulette has a slightly lower RTP due to its two zeros.
Typically 92%–96% RTP. Quite popular due to fast rounds and multipliers.
Volatility vs RTP
High volatility means bigger wins are possible but less frequent. Low volatility means smaller but more frequent wins. Choose a game based on your budget and patience.
Bankroll Management Guide
Smart players stick to a budget
Bankroll management is the most important part of responsible gambling. It means creating a plan for how you will manage your total gambling budget.
- Set a budget: Decide in advance how much you will spend per month or per session. Only use money that, if lost, will not affect your daily life.
- Divide into sessions: Split your total budget into smaller sessions. Instead of using your entire budget in one session, spread it across several sessions.
- The 1–5% per bet rule: Each bet should not exceed 1% to 5% of your total bankroll. This helps you keep your funds going over the long term.
- Stop after a good win: Take a break after a good win. Set aside a portion of your profit and try not to bet it again.
- Stop after a loss: When you reach a set loss limit (for example 50% of your total budget), stop for the day. Placing more bets to try to recover lost money most often leads to even bigger losses.
- Keep records: Write down your deposits, withdrawals and results for every session. This will help you understand your playing pattern and where changes are needed.
