Crash Games
A crash game is a fast-paced multiplier-based game where each round lasts anywhere from a few seconds to a few minutes. Aviator and JetX are popular examples of this type of game.
The rules are simple — place your bet before the plane (or rocket) flies away. The higher the multiplier climbs, the bigger your potential win. But the plane can crash at any moment, so cashing out at the right time is the smart move.
Auto Cash-Out: You can set an auto cash-out at a specific multiplier so you exit at your target profit without having to act manually.
Before you play, set a stop limit — decide in advance how much you are willing to lose before you stop. Play responsibly.

Each team faces 20 overs, with matches typically finishing in 3 to 4 hours. Sixes, wickets and powerplay betting are popular. BPL, IPL and PSL are played in this format.
One-Day (ODI)
Each team faces 50 overs in an all-day match. Top batter, total runs and first wicket markets are active. The ICC World Cup uses the ODI format.

Matches last up to 5 days with 4 innings. Match winner, draw, session betting and innings total markets are available.

Types of Slot Games
Classic Slots
Old-style 3-reel slots with simple rules. NetEnt's classic slots are an example of this type.

Animated 5-reel slots featuring bonus rounds and free spins. Pragmatic Play's Gates of Olympus is a popular title.
Jackpot Slots
Progressive jackpots where the prize keeps growing over time. Microgaming's games are well known in this category.
Megaways Slots
The reel height changes on every spin, which means the number of payways can reach into the thousands.
Cascading Reels
Winning symbols disappear and new ones fall from above — making multiple wins possible in a single spin.
Cluster Pays
A win is triggered when a set number of matching symbols land next to each other, using a cluster system instead of paylines. Pragmatic Play's Sweet Bonanza is an example of this type.

RTP and House Edge Explained
RTP (Return to Player) is a percentage that shows how much of the total amount wagered a game returns to players on average over the long term. For example, an RTP of 95% means that for every ৳100 wagered, an average of ৳95 is returned — but this is only a theoretical average, not a guarantee.
The typical RTP range for different types of games is generally as follows:
- Slots: Usually between 92% and 98%
- Blackjack: Up to around 99% with correct strategy
- Roulette (European): Approximately 94% to 97%
- Baccarat: Close to approximately 98%
House edge is the casino's mathematical advantage — that is, what you get by subtracting the RTP from 100%. For example, a game with a 96% RTP has a house edge of 4%.
A game with a higher RTP generally means less advantage for the casino, but in high-volatility games a single spin can bring a large swing in results.
Important: RTP is a mathematical average calculated over millions of spins. The outcome of any single session can differ greatly from this figure. Set limits and play responsibly.

RTP (Return to Player)
Return to Player — a theoretical measure of what percentage of the total amount wagered in a game is returned to players over the long term.
