Cricket Format Explained
Learn about the different cricket formats before placing your bets. Each format has its own betting markets and strategies.
T20
20 overs per innings. A match typically finishes in 3 to 4 hours. The fast pace, high scoring, and last-moment drama make it the most popular format among bettors. Betting markets include run rate, wickets, sixes, and match winner.
ODI (One-Day)
50 overs per innings. A match runs for 7 to 8 hours. The ICC Cricket World Cup is played in this format. The strategic depth makes in-play betting very appealing. Powerplay and middle-over betting markets are popular.
Test
Unlimited overs per innings, up to 5 days. The most traditional format in cricket. The possibility of a draw calls for a different betting strategy. Pitch conditions and weather play an important role.
The Hundred
100 balls per innings — even faster than T20. This format, held in England, is growing in popularity with new audiences. Bowling is done in sets of 10 balls each. New types of options are available in the betting markets.
Popular Cricket Leagues
Bangladesh teams play in BPL, making it especially appealing to local bettors. IPL's world-class players create a massive betting market. Bangladesh Tigers matches at the T20 World Cup attract the most bets.

Crash Games — fast multipliers
Aviator & JetX — How to Play
The crash game concept is simple: a rocket or plane takes off and the multiplier keeps rising. You need to cash out before it crashes.
- Place your bet before the flight begins
- Decide when to cash out as the multiplier rises
- Use the auto cash-out feature to exit automatically at a set multiplier
- Each round lasts only a few seconds — so you need to decide fast
- Set a stop-limit before you play — this is important
Warning: No "signal" or "prediction" service is reliable. Each round's result is independent and does not depend on previous rounds.

Never download from links shared in Telegram or Facebook groups — these may be fake.
Without this permission the APK will not install. On Android 8 and above you can grant this permission on a per-app basis.

RTP and House Edge Explained
What is RTP?
RTP, or "Return to Player," is a statistical figure that shows what percentage of the total money wagered on a game is returned to players over the long term. For example, a 95% RTP means that for every ৳100 wagered, an average of ৳95 is returned over the long term — but this is a theoretical average and results in each session can vary.
Typical RTP ranges for different games
RTP differs across game categories. Slot games typically show an RTP of 92% to 98%. Blackjack can reach an RTP of around 99% when played with the correct strategy. European Roulette generally falls between 94% and 97% RTP. Baccarat has a relatively high RTP on the player bet.
What is House Edge?
House edge is the other side of RTP — it is the casino's average advantage. Subtract RTP from 100% and you get the house edge. A slot with 96% RTP has a house edge of 4%. The casino relies on this small advantage to keep operating.
Why is it important to know this?
Knowing RTP lets you make informed decisions. Choosing higher RTP games can help reduce losses over the long term. Keep in mind, though, that every round is independent and there is no such thing as a "guaranteed win." RTP is a statistical average; results in short sessions can be completely different.
| Game Type | Typical RTP |
|---|---|
| Slots | 92%–98% |
| Blackjack | ~99% |
| Roulette (European) | 94%–97% |
| Baccarat | 95%–99% |
| Crash Games | Variable |
Note: RTP is a theoretical long-term average. It is not a guarantee of winnings. Play responsibly.
Bankroll Management Guide
- Set a budget: Decide on a fixed amount each month for entertainment. Treat that amount as an entertainment expense — losing it should not affect your daily life.
- Divide it into sessions: Split your total bankroll into smaller per-session budgets. Do not use your entire bankroll in a single session.
- The 1–5% rule per bet: Use between 1% and a maximum of 5% of your total bankroll on a single bet. This way a bad run cannot wipe out your entire balance.
- Walk away after a win: Set a specific winning target. Once you reach it, stop — the thought of "just one more" often turns a win into a loss.
- Set a loss limit: Decide on a maximum daily or weekly loss in advance and make sure you stop when you reach it. Chasing losses by placing more bets is dangerous.
Keep a record of your play: Write down how much you deposited, how much you won or lost. This will help you understand your playing habits and stick to your budget.

- Official support will never ask for your password or PIN.
- Be cautious of anyone on Telegram or Facebook offering extra bonuses while posing as an "agent" — these are often scams.
