Cricket Format Explained
Before betting on cricket, it is important to understand the differences between the various formats. Each format has its own pace, strategy and betting markets.
20 overs per team. Matches usually finish in 3 to 4 hours. Popular betting markets include match winner, top batter and highest-scoring over.
50 overs per team. A full-day match. Live betting and innings total run markets stay active throughout.
A 5-day match with 2 innings per team. Match draw, series result and special milestone betting are available.
100 balls per team. A new format from England, fast-paced and exciting. Starts in the afternoon and ends in the evening.
Popular Leagues
BPL is Bangladesh's own T20 league — held in Dhaka with massive excitement. Betting markets are also available for international leagues like IPL and BBL.
How to Read Odds
Understanding odds is one of the most important skills in betting. Being able to read odds correctly helps you make smarter decisions.
Decimal Odds
The simplest format. Place a ৳500 bet at odds of 1.80 — if you win, you get back ৳500 × 1.80 = ৳900 (including your original stake). Profit is ৳400.
Implied Probability
Odds of 1.80 mean the probability of winning is roughly 55.5%. Formula: (1 ÷ odds) × 100. This helps you understand how likely the bookmaker thinks an outcome is.
| Format | Example | Meaning |
|---|---|---|
| Decimal | 1.80 | ৳80 profit on a ৳100 bet |
| Fractional | 4/5 | 4 profit for every 5 staked |
| American | -125 | ৳100 profit on a ৳125 bet |

RTP and House Edge Explained
RTP, or Return to Player, is a theoretical figure that indicates what percentage of total bets placed on a given game is returned to players over the long term. For example, if a game has an RTP of 96%, an average of ৳96 is distributed back to players for every ৳100 wagered.
House edge is the flip side of RTP — it is the percentage of total bets that the casino or betting operator keeps. In the example above, the house edge is 4%. This margin covers the cost of running the platform.
Typical RTP ranges vary by game type. Slots generally show an RTP of 92%–98%. Blackjack can reach an RTP of around 99% with correct strategy. European Roulette has an RTP of roughly 94%–97%.
Keep in mind that RTP is a long-term average — results can vary greatly in the short term. Volatility, or variance, refers to how often and how large the rewards are. High-volatility games pay out larger rewards less frequently, while low-volatility games pay out smaller rewards more often.
