Types of Slot Games
Learn about the different types of slot games — each has its own mechanics and excitement.
Classic Slots
Traditional slots with three reels and simple paylines. PG Soft's Lucky Piggy is an example of this type of straightforward mechanic.
Video Slots
Modern five-reel slots with rich animations and bonus rounds. Pragmatic Play's Gates of Olympus is a popular example.
Jackpot Slots
A portion of each bet builds up to create a massive jackpot. NetEnt is known for this type of progressive jackpot game.
Megaways Slots
The reels change size on every spin, creating thousands of ways to win. Pragmatic Play's Sweet Bonanza uses this mechanic.
Cascading Reels
After a win, the symbols disappear and new symbols fall from above — giving you the chance to win multiple times on a single spin.
Cluster Pays
A win occurs when a set number of matching symbols are adjacent to each other. Pragmatic Play's Sugar Rush uses this method.
Cricket Format Explained
Betting strategies differ across cricket formats. Get to know each format.
T20
Just 20 overs per team, match finishes in 3–4 hours. In-play betting is most popular in this fast-paced format. BPL and IPL are played in this format.
BPL • IPL • T20 WCOne Day (ODI)
A 50-over one-day match that demands attention throughout the day. ICC ranking-based markets and series betting are most popular.
ICC • World CupTest
A match of up to 5 days with two innings per team. Session betting and draw markets are the special features of this format.
Bangladesh TigersThe Hundred
A new 100-ball format with 100 deliveries per team. Popular in England and well suited for fast-moving betting markets.
BBL • PSLAmong players in Dhaka, betting on BPL and Bangladesh Tigers international matches is most popular. Special offers are available on our platform during IPL and the T20 World Cup.
Fishing and Arcade Games
Fishing games are not just about luck — knowing the right strategy can make every shot more effective.
Cannon Levels and Fish Multipliers
Each cannon has a different power level — a more powerful cannon costs more points but can take down bigger fish. Small fish have lower multipliers, while boss fish multipliers are much higher.
Boss Fish Strategy
Boss fish appear on screen for a short time but the payout is much higher. Multiple players shooting at a boss fish at the same time gives an advantage.
Types of Arcade Games
- Fishing shooters: JILI's Mega Fishing, Ocean King Jackpot, Bombing Fishing
- Bingo variants: chance to win jackpots with different card layouts
- Crash games: Spribe's Aviator — cash out while the multiplier is rising
- Card arcade: fast-paced card games like Teen Patti Joker
Keep track of the cost of each shot. Set a budget before you play and try not to exceed your limit.
What Is a Betting Exchange and How Does It Work
In a regular sportsbook you bet against the bookmaker. In a betting exchange you bet against other players — the platform acts only as an intermediary and takes a small commission.
There are two fundamental concepts in an exchange — Back and Lay. Back means betting in favour of a team or player winning. Lay means betting against that outcome — meaning you take on the role of a small bookmaker.
Example: Bangladesh vs India T20 Match
| Back (Bangladesh will win) | Lay (Bangladesh will not win) |
|---|---|
| Odds: 2.5 Stake: ৳500 Profit if wins: ৳750 |
Odds: 2.5 Liability: ৳750 Win if (Bangladesh loses): ৳500 |
Exchange odds are generally better than sportsbook odds because there is no built-in margin — only commission. However, Lay bets can carry higher liability, so stay aware of your budget.
RTP and House Edge Explained
RTP (Return to Player) is the theoretical percentage of total wagers that a game returns to players over the long term. For example, a 96% RTP means that on average ৳96 comes back for every ৳100 wagered — but this is an average across millions of spins, not a guarantee for any single session.
Typical RTP ranges seen across different game categories: video slots generally 92–98%, blackjack around 99% (with correct strategy), roulette around 94–97% (higher in the European variant). These figures depend on a game's mechanics and rules.
House edge is the flip side of RTP — what the casino keeps. A 96% RTP means a 4% house edge. Slots tend to have a higher house edge because of their entertainment value and jackpot opportunities. Table games generally have a lower house edge.
Knowing this helps you understand which games can have a greater impact on your budget over a longer session. Choosing games with a lower house edge is a smart move — but keep in mind that all casino games are for entertainment, not a reliable source of income.
