Cricket Formats Explained
Understanding the differences between formats is important for cricket betting. The betting markets also vary by format.
T20
20 overs per innings, with matches typically finishing in 3–4 hours. In-play betting is most popular in this fast-paced format. BPL, IPL, and T20 World Cup are all played in this format.
ODI (One-Day)
50 overs per innings, with matches lasting around 7–8 hours. The ICC Cricket World Cup is played in ODI format. Betting markets are constantly updated as conditions shift mid-match.
Test Cricket
Matches last up to five days, with two innings per team. The possibility of a draw makes the betting market more complex than T20. Session betting and top wicket-taker markets are popular.
The Hundred
Only 100 balls per innings — a newer format played in England. This extremely fast-paced format can see dramatic turns on every ball.
Notable leagues: BPL, IPL, BBL, and PSL — these are the leagues that Bangladesh Tigers supporters follow most closely.
Types of Slot Games
If you are new to slot games, start by learning how the different types work and which one suits your preference.
Classic Slots
Three-reel slots in the traditional style, featuring cherry, bar, and seven symbols. Ideal if you prefer quick gameplay with simple rules. NetEnt is known for producing this type of classic slot.
Video Slots
Modern five-reel slots featuring animations, theme music, and multiple bonus features. Pragmatic Play's Gates of Olympus and Sweet Bonanza are well-known examples in this category.
Jackpot Slots
In progressive jackpot slots, a small portion of each bet is added to the jackpot pool. When a specific symbol combination is triggered, there is a chance to win a large prize. Microgaming is one of the most well-known providers in this category.
Megaways Slots
The height of the reels changes on every spin, creating thousands of ways to win. This mechanic was created by Big Time Gaming and is now used by many providers.
Cascading Reels
Winning symbols are removed from the board and new symbols fall into place, making it possible to win multiple times in a single spin. Pragmatic Play's Sweet Bonanza is a familiar example of this mechanic.
Cluster Pays
A win occurs when multiple identical symbols form a cluster side by side. This goes beyond traditional paylines and offers a different style of gameplay. NetEnt and other studios build games using this mechanic.
Jackpot Games — A Chance at Big Wins
cb77 offers several types of jackpot games. Each has a different prize structure — learn how each one works.
Progressive Jackpot Slots
A small portion of every bet is added to the main jackpot pool. When a specific symbol combination lands, that pool can be won.
Fixed Jackpot Slots
The maximum prize is set in advance. When special symbols line up on the reels, the full prize can be won — in any session.
Live Casino Side-Bet Jackpot
Placing a side bet in live Baccarat or Blackjack gives you the chance to win a separate jackpot. It adds extra excitement alongside the main bet.
Crash Game Multiplier
In crash games like Aviator, the multiplier rises continuously — cash out before the crash and you win at that multiplier.
RTP and House Edge Explained
RTP stands for "Return to Player" — the rate at which money is returned to players. In simple terms, if a game has an RTP of 96%, then in theory an average of ৳96 is returned to players for every ৳100 wagered. This figure is calculated over millions of rounds and does not guarantee any outcome in a single session.
House edge is the flip side of RTP. If the RTP is 96%, the house edge is 4% — meaning the casino operates with a small mathematical advantage in its favour. This margin is what keeps the casino running and helps build prize pools.
| Game Type | Typical RTP Range | House Edge (Approximate) |
|---|---|---|
| Slot Games | 92% – 98% | 2% – 8% |
| Blackjack | ~99% | ~1% |
| Roulette (European) | 94% – 97% | 2.7% |
| Baccarat | ~98.9% | ~1.1% |
A smart player always checks a game's RTP and volatility before starting. High-volatility games offer the chance of bigger wins but come with larger swings; low-volatility games pay out smaller amounts but more frequently. Choosing a game based on your budget and risk tolerance is the right approach.
Crash Games — Fast-Paced Multipliers
Crash games like Aviator (Spribe) and JetX are extremely fast-paced. In each round, a plane or rocket takes off and the multiplier rises along with it. Bets must be placed before or right at the start of a round.
The key strategy is pressing the cash-out button at the right moment — before the plane crashes. Most crash games have an auto cash-out option where you can set a multiplier in advance. Each round lasts anywhere from a few seconds to a few minutes.
Important: Set a stop-limit for yourself before you start playing. The fast pace of crash games can make it difficult to manage your budget — decide in advance how much you are willing to lose before ending a session.

Bankroll Management Guide
Budget planning is the most important skill for enjoying online gaming. Proper bankroll management gives you more time to play and reduces the risk of financial loss.
Set aside only the amount you can afford to lose each month without it affecting your daily life as your gaming budget. This amount should be proportional to your monthly income.
Split your monthly budget into smaller sessions. Instead of spending the entire budget in one session, set a separate limit for each session — this gives you the chance to play multiple times.
Experienced players typically place only 1 to 5 percent of their session bankroll on each bet. This way, a bad streak cannot wipe out your entire balance.
The urge to play "just a little more" after a good win is natural — but it often gives back your winnings. Set a profit target in advance and end the session once you reach it.
Stop immediately once you've lost a set amount in a session. Record each session's deposits, withdrawals, and results in a notebook or app — this helps you understand your own patterns.
