Cricket Format Guide
Betting markets differ across cricket formats. Understanding the right format makes your betting strategy clearer.
| Format | Overs per Innings | Match Duration | Popular Betting Markets |
|---|---|---|---|
| T20 | 20 overs | 3–4 hours | Match winner, total runs, number of sixes, powerplay score |
| ODI (One-Day) | 50 overs | 7–8 hours | Match winner, top run scorer, over of first wicket fall |
| Test | Unlimited (5 days) | Up to 5 days | Match draw/win, innings total runs, series winner |
| The Hundred | 100 balls | 2.5–3 hours | Match winner, number of wickets, top scorer |
T20 Leagues — BPL, IPL, BBL, PSL
BPL (Bangladesh Premier League) is the most familiar league for Bangladeshi players. IPL (Indian Premier League) is the world's biggest T20 league and offers the highest number of betting markets. BBL is Australia's and PSL is Pakistan's main T20 tournament — both are easy to bet on from Bangladesh.
For example — in a T20 match between Bangladesh and India, you can bet on markets like "Match Winner", "Top Runs", or "First Six". See the 'How to Read Odds' section below to understand what the odds mean for each market.
RTP and House Edge Explained
RTP (Return to Player) is a game's theoretical return rate — how much money comes back to players out of every ৳100 wagered over the long run. For example, a 96% RTP means theoretically ৳96 is returned and ৳4 goes to the house. However, this is an average across millions of rounds — results in any single session can be completely different.
RTP typically falls within these ranges by game type: slot games around 92–98%, Blackjack up to around 99%, Roulette generally 94–97%. These figures are verified by game designers and independent auditors — so it is always wise to play games from reputable providers.
House edge is the flip side of RTP — 100% minus RTP. So a 96% RTP means a 4% house edge. Games with a higher house edge carry a greater chance of loss over the long run. That is why choosing games with higher RTP and setting a budget before playing is the sensible approach.
Knowing the RTP alone is not enough — volatility also matters. Low-volatility games deliver small wins frequently, while high-volatility games deliver larger wins less often. Choosing a game that matches your budget and playing style is the right strategy.
How to Read Odds
The most common format in online betting is Decimal Odds. They are easy to read — simply multiply the odds by your stake to get the total return.
Example: You place a ৳500 bet at odds of 1.80.
Total return = ৳500 × 1.80 = ৳900
Profit = ৳900 – ৳500 = ৳400
Implied probability is easy to work out: 1 ÷ odds = probability. So at odds of 1.80, the implied probability is 55.6%. That means the bookmaker considers there to be roughly a 56% chance of this event occurring.
| Odds Format | Example | Explanation |
|---|---|---|
| Decimal | 1.80 | The simplest format — multiply directly |
| Fractional | 4/5 | Numerator ÷ denominator = profit ratio (UK format) |
| American | -125 | Negative = favourite; positive = underdog |
Quick Reference
Odds 1.00 = no profit
Odds 2.00 = profit equal to stake
Odds 3.00 = double your stake as profit
Higher odds → higher risk

Trusted Game Providers

Fishing and Arcade Games
Fishing games offer a different kind of experience — you use a cannon to catch fish floating across the screen. Each fish has a different value: smaller fish carry smaller rewards, while big boss fish come with large multipliers. Upgrading your cannon increases its power but also raises the cost per shot.
Fishing Games
JILI Mega Fishing, Ocean King — big rewards on boss fish.
Arcade
Boom Legend, Dinosaur Tycoon — fast rounds, simple rules.
Blast Game
Explosive mechanics — one shot delivers rewards across the screen.
Target Shooter
Aim at specific targets — the better your aim, the bigger the win.
Tips for Managing Shot Costs
- Start with low-level cannons to get a feel for the game environment
- Don't waste too many shots on small fish — wait for the boss fish to appear
- Set your total shot budget for each session before you start
