Introduction to Cricket Betting Markets
Before placing bets on BPL, IPL or the T20 World Cup, find out which markets are the most popular.
Match Winner
Bet in advance on which team will win the match. Example: Bangladesh vs India — bet on a Tigers win.
Toss Winner
Decide which team will win the toss before the match starts. A simple market that settles quickly.
Top Batsman
Predict who will be the highest run-scorer in their team. Example: Shakib Al Hasan.
Total Runs Over/Under
Bet on whether the total runs in an innings will be over or under a set number — pick one of the two.
Runs in an Over
Bet on how many runs will be scored in a specific over — the most exciting bet in live betting.
Player of the Match
Bet in advance on who will be the best player of the match — odds are generally attractive.
In live in-play betting, odds change quickly when a wicket falls — make your decision at the right moment.
Live Casino Tables
Play directly with a real dealer — enjoy the full casino experience from home.
Baccarat
The player or banker closest to 9 points wins. Table limit example: ৳50 – ৳50,000.
Roulette
Predict the number where the ball lands on the spinning wheel. Table limit example: ৳10 – ৳20,000.
Blackjack
Get as close to 21 as possible — beat the dealer without going bust. Limit example: ৳20 – ৳30,000.
Live Andar Bahar
Pick a card and bet on the Andar or Bahar side. Fast and simple. Limit example: ৳5 – ৳10,000.
Game Show Wheel
Choose a segment on a giant spinning wheel — chances of winning increase in multiplier rounds. Limit example: ৳10 – ৳8,000.
Sic Bo Live
Bet on the total or combination of three dice — multiple betting options available. Limit example: ৳20 – ৳15,000.
Fishing and Arcade Games
Fish shooting games are very popular in Bangladesh — knowing the right strategy can earn you good rewards alongside the entertainment.
Cannon Level System
In fishing games you can upgrade your cannon's power — a higher-level cannon can take down big fish more easily, but the cost per shot is also higher. Use a lower level for small fish and a powerful cannon for boss fish.
Fish Multipliers
Each fish has its own multiplier value — small fish give fewer rewards but are easier to catch, while large and rare fish give more. A good strategy is to steadily collect points by targeting many small fish on a regular screen.
Boss Fish Challenge
A giant boss fish occasionally appears on screen — defeating it brings a big reward. Multiple players shooting at it together can take it down faster. However, hunting the boss alone can cost a lot of ammunition.
Cost Management Tips
Set a fixed cost per shot in advance and keep a portion of your total budget as a limit. Instead of wasting all your shots on high-multiplier fish, focus on medium-sized fish. Take regular breaks and do not increase your bets to cover losses.
RTP and House Edge Explained
RTP, or Return to Player, is the long-term payout rate of a game. If a game has an RTP of 96%, theoretically ৳96 is returned for every ৳100 wagered — but this is an average across millions of spins, not a guarantee for any specific session.
RTP typically varies across different game types. Slot games usually have an RTP between 92–98%. In blackjack, following the correct strategy can bring RTP close to 99%. In roulette, the European variant generally has an RTP of 94–97%. Live baccarat tends to have a comparatively higher RTP.
House edge is the opposite of RTP — it is the casino's profit margin. An RTP of 96% means a house edge of 4%. Games with a higher RTP have a relatively lower chance of long-term loss, so it is wise to check a game's RTP before playing.
Volatility, or variance, also matters. High-volatility games pay out large wins less frequently, but the payouts are much bigger when they do come. Low-volatility games pay out smaller rewards more often. Choose the right game based on your budget and patience.

Betting Terms / Glossary
Learn the common terms used in online betting and casinos — essential for new players.
RTP (Return to Player)
The long-term average payout rate of a game. For example, a 96% RTP means an average of ৳96 is returned for every ৳100 wagered.
House Edge
The casino's permanent mathematical advantage. If RTP is 96%, the house edge is 4% — this is a standard feature of every game.
Wager / Stake
The amount of money placed on a single bet. The higher the stake or wager, the greater the potential reward if you win.
Odds
A mathematical expression of the probability of an event occurring. Higher odds mean a bigger reward but a lower probability.
Parlay / Accumulator
Combining multiple bets together where all of them must win. The risk is higher but the reward can be much larger.
Live Bet

Bankroll
The total budget set aside for betting or casino play. Healthy bankroll management is the key to long-term enjoyment.
Volatility
The degree of variation in a game. High volatility means large rewards come less frequently; low volatility means smaller rewards come more often.
Free Spin
The opportunity to spin for free in a slot game — usually awarded through bonuses or scatter symbols.
Wagering Requirement
The condition specifying how many times a bonus must be wagered before it can be withdrawn. Example: 10x means ৳50,000 in bets are required for a ৳5,000 bonus.
Spread
In sports betting, a hypothetical points difference between two teams used to ensure balanced wagering on both sides.
