RTP and House Edge Explained
Before playing at an online casino, it is very important to understand RTP (Return to Player) and House Edge. These two concepts will help you choose the right game and plan your budget.
RTP is a percentage that indicates how much of the total money wagered in a game will be returned to players over the long term. For example, if a game has an RTP of 96%, then theoretically ৳96 comes back for every ৳100 wagered — however, this is the average across millions of rounds, not a guarantee for a single session.
RTP generally varies across different types of games. Slot games typically have an RTP ranging from 92% to 98%. Table games like blackjack can reach close to 99% RTP when the correct strategy is followed. For roulette, it usually falls between 94% and 97%.
House Edge is the opposite of RTP — it is the percentage of each bet that the casino retains on average. For example, a 96% RTP means a 4% house edge. This is the strategy game developers and providers use to remain profitable over the long term.
Volatility or Variance is another important concept. In high-volatility games, large prizes come less frequently but are greater in amount when they do. In low-volatility games, smaller prizes come more frequently. Choosing a game based on your own budget and risk tolerance is the smartest approach.
Remember, online casino games are ultimately for entertainment. Understanding RTP and House Edge helps you make more informed decisions, but no strategy guarantees long-term winnings.

Learn about different types of slot games and choose the one that suits you.
Classic Slots
Traditional slots with three reels and simple paylines. These are ideal for beginners as the rules are very straightforward. NetEnt is well known for creating this type of classic game.
Video Slots
Modern five-reel slots featuring themes, animations, free spins, and bonus rounds. Pragmatic Play's Gates of Olympus and Sweet Bonanza are examples of this type of game.
Jackpot Slots
In progressive jackpot slots, a portion of every bet is added to a massive prize pool. The main jackpot is paid out in one large sum. Microgaming is well known for this type of game.
Megaways Slots
Because the reel size changes with every spin, thousands of winning combinations can be created. Big Time Gaming is the inventor of this mechanic.
Cascading Reels
Winning symbols disappear and new symbols fall from above. This gives you a chance to win multiple times in a single spin. Pragmatic Play's Sugar Rush is a popular example of this mechanic.
Cluster Pays
Instead of paylines, you win by matching symbols in groups or clusters. The game is usually played on a large grid. PG Soft is skilled at making this type of game.
Fishing & Arcade Games
Fishing games are quickly gaining popularity among players in Bangladesh. Providers like JILI create engaging fishing games including Mega Fishing, All-star Fishing, and Bombing Fishing.
Cannon Level
Upgrading the cannon's power makes it easier to catch big fish, but each shot costs more. Keep it in line with your budget.
Boss Fish
Hitting a special boss fish gives a big reward. They take more shots to defeat, but the reward is much greater.
Fish Multiplier
Different fish have different multipliers. Hitting a rare fish gives a much higher reward than a common fish.
Shot Management
Play by measuring the cost of each shot. Using a big cannon on small fish is wasteful. Set a budget limit and enjoy the game.
Betting Glossary
Learn the common terms used in online betting and casinos and become a more confident player.
RTP (Return to Player)
A measure of what percentage of total bets a game returns to players over the long term. A higher RTP means relatively better conditions for the player.
House Edge
The percentage of each bet that the casino keeps on average. It is the opposite of RTP — subtract RTP from 100% to get the house edge.
Wager
The amount of money you bet in each round. Wagering requirement refers to how many times you must play through that amount before you can withdraw a bonus.
Odds
A numerical expression of the probability of an event occurring in betting. Higher odds mean a potentially larger reward but a lower chance of winning.
Parlay / Accumulator
Multiple bets linked together where all bets must win. The reward is larger but losing any single bet means losing everything.
Live Bet
The ability to place bets in real time while a match or game is in progress. Odds change as the situation develops.
Cash Out
The ability to withdraw part or all of your winnings before a match ends. Used to reduce risk.
Bankroll
The total amount of money set aside for gaming. Proper bankroll management is the foundation of responsible gaming.
Volatility
A measure of the frequency and size of rewards in a game. High volatility means larger but less frequent rewards; low volatility means smaller but more frequent rewards.
Free Spins
Free slot spins provided by the casino. They are given as a bonus and allow you to play without spending any money.
Spread Betting
A method of betting not on a specific outcome but on a range of outcomes. Profit or loss is determined based on the difference.
Wagering Requirement
You must play through the bonus amount, or the total bonus plus deposit amount, a set number of times before you can withdraw it. At 77bl this is just 20x.
