Cricket Format Explained

Learn about the different cricket formats and understand how to bet on each one.

T20

20 overs per team. Matches typically finish in 3 to 3.5 hours. The fast pace and excitement make it the most popular format in the betting market. BPL, IPL, BBL, and PSL are all played in this format.

ODI (One-Day)

50 overs per team. Matches last 7 to 8 hours. The ICC World Cup is held in this format. Point spreads and match winners are popular betting markets, along with run score markets.

World Cup

Test

A long five-day format where each team plays two innings. Greater tactical depth is involved, and a draw is a possible result — so the betting market is built around three potential outcomes.

Strategic

The Hundred

A newer format developed in England — 100 balls per team. Each bowler can bowl a maximum of 10 balls. Shorter and more intense than T20. The betting market also operates under a different structure.

BPL Bangladesh Premier League

IPL Indian Premier League

BBL Big Bash League

Cricket Partnerships in the Industry

Cricket sponsorship has become a growing tradition in Bangladesh's online betting industry. On the international stage, various operators are building brand recognition by partnering with cricket teams and players.

For example, Babu88 has affiliated with the Montreal Tigers and Colombo Strikers. Crickex has sponsored various regional cricket tournaments. Jeetbuzz has signed international cricketer Andre Russell as a brand ambassador.

These kinds of partnerships are making betting platforms more familiar to Bangladesh's cricket-loving audience. gb77 is also committed, as part of this cricket culture, to delivering the best cricket betting experience for players in Bangladesh.

RTP and House Edge Explained

Understanding RTP and house edge before you play will help you make more informed decisions.

What is RTP (Return to Player)?

RTP, or Return to Player, is a percentage that gives a theoretical estimate of how much money players will get back from a game over the long term. For example, if a game has an RTP of 96%, then theoretically a player will get back an average of ৳96 for every ৳100 wagered.

However, this is a long-term average — results can vary on each spin or hand. RTP never guarantees a specific win.

Typical RTP Ranges for Different Games

Slot machines: typically 92% to 98%
Blackjack: around 99% with optimal strategy
Roulette: 94% to 97% on the European variant
Baccarat: typically close to 98%
Video poker: varies depending on the hand

What is House Edge?

House edge is the flip side of RTP — the percentage the casino or operator retains on average from each bet. If the RTP is 96%, the house edge is 4%. This is not theft — it is the standard structure of the casino business, followed worldwide.

Why Does It Matter?

Understanding RTP and house edge allows you to choose games more wisely. Games with a higher RTP offer better chances over the long term. Most importantly, play within your own budget and for entertainment.

How to Read Odds

Odds are the foundation of betting. gb77 primarily uses decimal odds, which are the easiest for players in Bangladesh to understand.

Decimal Odds Example

Say you place a ৳500 bet at odds of 1.80. If you win, total return = ৳500 × 1.80 = ৳900. This includes your original ৳500 stake, with a profit of ৳400.

Implied Probability

The probability of winning can be calculated from odds. Formula: 1 ÷ odds × 100. Implied probability of 1.80 odds = 1 ÷ 1.80 × 100 ≈ 55.6%.

Comparison with Other Formats

Fractional odds: British style, e.g. 4/5 means ৳4 profit on a ৳5 bet.

American (Moneyline) odds: expressed with +/- signs. +150 means ৳150 profit on a ৳100 bet; -150 means you need to bet ৳150 to win ৳100 profit.

Proof of address (utility bill / bank statement)
