Cricket Formats and Betting Markets
Understanding the different cricket formats helps you make better decisions when betting. The types of markets vary across formats, so it is important for any informed bettor to know the characteristics of each format.
T20
20 overs per innings, with a full match usually finishing in 3–4 hours. This is the fastest and most exciting format. Popular betting markets include match winner, top batter, highest wicket-taker, first over runs, and innings six count. BPL, IPL, and T20 World Cup are held in this format.
One-Day (ODI)
50 overs per innings, with a match typically lasting 7–8 hours. Strategy plays a greater role in this format. Many bettors place wagers based on the Bangladesh Tigers' performance. Top run scorer, partnership runs, and fall of wicket markets are more common in ODIs.
Test
A 5-day match with 2 innings per team. Test betting is the most complex — pitch conditions, weather, and day-by-day session betting all play an important role here.
The Hundred
100 balls are played per innings, with the match finishing in roughly 2.5 hours. This newer format, popular in England, is gaining a following quickly.
Major Leagues
BPL (Bangladesh Premier League) — the country's top T20 league and the most popular among local fans. IPL — the world's biggest cricket league. BBL (Australia) and PSL (Pakistan) — both feature world-class players. All of these leagues are available for betting on 57j77.

Mega Fishing
Fishing and Arcade Games
Fishing games are growing in popularity among Bangladeshi players. In these games, you use a cannon to catch fish in the sea — each fish has its own multiplier.
How does it work?
A set bet amount is placed for each shot — this is the "cost per shot". Small fish are easier to catch but the rewards are lower. Catching a large fish or "boss fish" can earn you a much higher multiplier. Upgrading the cannon level increases both the power and cost of each shot.

Use bombs to catch many fish at once

A Guide to Understanding RTP and House Edge
RTP (Return to Player), or the percentage returned to the player, refers to how much a game pays back on average for every ৳100 wagered over the long term. For example, an RTP of 95% means an average return of ৳95 for every ৳100 — but this is a long-term statistic and results in individual sessions can vary.
Typical RTP ranges across different game categories are: slots generally range from 92%–98%, blackjack around 99%, roulette from 94%–97%, and video poker from 96%–99.5%. It is worth keeping in mind that a higher RTP does not always guarantee a win.
House edge is the flip side of RTP — it represents the casino's average profit margin. An RTP of 95% means a house edge of 5%. A lower house edge is more favorable for the player. In blackjack and video poker, applying the right strategy can reduce the house edge significantly.
Knowing the RTP before you play lets you choose games more wisely and makes budget management easier. High volatility games can deliver big wins but carry a higher risk of running through your session budget quickly. Low volatility games pay out smaller amounts but more frequently.
Typical RTP Ranges
- Slots: 92% – 98%
- Blackjack: ~99%
- Roulette: 94% – 97%
- Video Poker: 96% – 99.5%
- Baccarat: ~98.9%

Cricket Sponsorship and Partnership Trends
Online gaming platforms around the world are strengthening their ties with cricket. This trend is clearly visible in the Bangladeshi market too — various operators are forming partnerships with cricket tournaments and teams.
As examples, Babu88 has worked with Bangladeshi and international cricket leagues and is known for its ties with Montreal Tigers and Colombo Strikers. Crickex has done regional sponsorships at various cricket events across South Asia. Jeetbuzz attracted wide attention by appointing international cricket star Andre Russell as brand ambassador.
This industry trend shows that cricket and online betting are becoming complementary to each other. Bangladeshi players are most active during BPL and T20 World Cup seasons. Cricket betting markets on 57j77 are wide-ranging — from live in-play to pre-match betting, all types of options are available.
What is a Betting Exchange and how does it work?
In a regular sportsbook, you bet against the casino — the casino sets the odds. But in a betting exchange, you bet against other players. The platform takes a small commission in the middle.
Back vs Lay Betting
Back bet: You think a team will win, so you back that team. This works just like regular betting.
Lay bet: You think a team will lose, so you bet against that team. This means you are acting in the role of the bookmaker.
The advantage of an exchange is that odds are generally better than the market because they are set by other players. However, potential losses can be higher on lay bets, so caution is important.
| Feature | Back Bet | Lay Bet |
|---|---|---|
| What do you do? | Bet on winning | Bet on losing |
| Who decides? | Accept market odds | Set the odds |
| Maximum profit | According to the bet odds | Equal to the opponent's bet |
| Maximum loss | Original bet amount | Odds × bet amount |
| Commission? | Applicable on wins | Applicable on wins |
