RTP and House Edge Explained
RTP stands for "Return to Player" — the share returned to the player. It is a percentage that shows how much a game can return on average per ৳100 wagered over the long term. For example, a 96% RTP means the game will return an average of ৳96 for every ৳100 wagered over the long term — but this is a statistical average, not a guarantee for any single session.
Typical RTP ranges vary by game category: slot games generally fall between 92%–98%, blackjack around 99%, and roulette between 94%–97%. It is therefore wise to check the RTP before choosing a game.
House edge is the opposite of RTP: subtract the RTP from 100 and what remains is the casino's own advantage. A game with 96% RTP has a house edge of 4%. This does not mean you will always lose — good wins in the short term are entirely possible — but understanding it will help you set your budget.
Having an understanding of RTP and volatility (level of risk) before you start betting will help you choose games more wisely and manage your bankroll more effectively.

Keep in mind
- RTP is a long-term statistic — it can vary within a single session.
- High-volatility games offer a greater chance of big wins, but wins occur less frequently.
- Set a budget before you play and stay within your limits.
Fishing & Arcade Games
In fish-shooting games you control a cannon that catches fish. Each fish has its own multiplier — smaller fish carry smaller rewards, but catching a boss fish can win you a big prize.
Classic Fishing
Standard fish catching — the ideal starting point for new players.
Boss Fish Hunt
Catch the massive boss fish — win big multipliers.
Bomb Fishing
Use explosive shots to catch multiple fish at once.
Arcade Style
Test your reflexes in fast-paced arcade games.
Tip: Increasing the cannon level raises the cost per shot. Use a high level for boss fish and save by using a lower level for regular fish.

What is a wagering requirement?
Wagering means you must place a specified amount in bets before withdrawing bonus funds. Example: ৳2,000 bonus × 20 = ৳40,000 must be wagered before withdrawing bonus winnings.
Game Contribution
Not all games may count equally toward the wagering requirement. Slot games generally count in full, while table games count partially. Read the terms and conditions for detailed rules.
Maximum Bet While a Bonus Is Active
There is a limit on how much you can bet per wager while a bonus is active. Exceeding this limit may result in the bonus being cancelled. So keep your bets within the limit while a bonus is active.
Bonus Validity & Cash-Out Limits
Every bonus has an expiry period. If wagering is not completed within that period, the bonus is forfeited. The maximum amount that can be withdrawn from a bonus is also pre-determined.
Betting Terminology / Glossary
Simple explanations of common betting and casino terms for new players.
RTP (Return to Player)
The percentage of the total amount wagered that a game returns to players on average over the long run, per ৳100 bet.
House Edge
The casino's statistical advantage. What remains after subtracting RTP from 100%. Example: 96% RTP = 4% House Edge.
Wager / Stake
The amount of money you place on each bet. This is the core amount you are putting at risk.
Odds
A numerical expression of the probability of an event occurring. The higher the odds, the greater the potential payout but the lower the probability.
Parlay / Accumulator (Parlay)
Combining multiple bets into one, where a big reward is paid out only if all outcomes are correct. One wrong result means losing everything.
Live Bet
Placing bets in real time while a game is in progress. It gives you the chance to make decisions based on how the match is unfolding.
Cashout
The ability to secure a partial or full profit from a bet before the match has ended.
Bankroll
Your total allocated budget for gaming. Managing your bankroll properly is the key to playing long-term.
Volatility
The level of risk in a game. High volatility = large but less frequent wins; low volatility = smaller but more frequent wins.
Free Spin
The opportunity to spin for free in a slot game. Usually obtained through bonuses or special symbols.
Wagering Requirement
The number of times you must bet before a bonus or winnings can be withdrawn. For example, 20x means you must wager 20 times the bonus amount.
Spread
In sports betting, the predetermined points difference between two teams that creates a level playing field.
