RTP and House Edge Explained
RTP, or Return to Player, is a percentage that represents how much a game returns to players over the long term. For example, if a game has an RTP of 95%, in theory an average of ৳95 is returned for every ৳100 wagered — though in practice this is an average across millions of rounds. This rate does not apply to any single session.
RTP varies by game type. Slot games generally range from 92% to 98%, while skill-based games like Blackjack can reach close to 99% RTP with the right strategy. Roulette typically offers 94% to 97% RTP (higher in European Roulette, lower in American Roulette).
House edge is the flip side of RTP — the percentage the casino retains over the long term. A 95% RTP means a 5% house edge. This is not a guarantee that players will lose, but rather the underlying mathematical structure of the game.
It is wise to understand RTP and house edge before you play. A higher RTP means your money is more likely to last longer. Keep in mind that all games are powered by a Random Number Generator (RNG), so every round is independent and not influenced by previous results.
Typical RTP by Game Type
| Game | Typical RTP |
|---|---|
| Slot Games | 92% – 98% |
| Blackjack | ~99% |
| Roulette | 94% – 97% |
| Baccarat | ~98.9% |
How to Read Odds
Understanding odds before you start betting is important. Taking a little time to learn them will improve your decision-making.
Decimal Odds
The most common format in Asia. Odds × stake = total return.
Example: ৳500 stake, odds 1.80 → total return ৳900 (profit ৳400).
Implied probability = 1 ÷ odds × 100. So odds of 1.80 = 55.6% probability.
Fractional Odds
Popular in British horse racing. 4/1 means ৳4 profit for every ৳1 staked.
Example: ৳500 stake, odds 4/5 → profit ৳400, total returned ৳900.
To convert to decimal: (numerator/denominator) + 1. So 4/5 = 1.80 decimal.
American Odds (Moneyline)
Expressed as positive (+) or negative (-) numbers.
Example: +150 means ৳150 profit on a ৳100 stake. -120 means a ৳120 stake returns ৳100 profit.
Less common on Asian sites, but used on some international platforms.

Fishing & Arcade Games
Fishing games are not just about luck — knowing the right strategy can help you get more out of every shot.
How does it work?
In fish-shooting games, you hunt fish in the ocean using a cannon. Each shot has a set cost, and killing a fish earns you points or rewards based on its multiplier. Increasing the cannon level raises your chances of catching bigger fish, but also increases the cost per shot.
🐠 Common Fish
Low multiplier, but easy to kill. A good way for new players to build up points.
🦈 Boss Fish
High multiplier and big rewards — but they take more shots to kill, so the cost is higher.
💣 Mega Fishing
JILI's special arcade mode where a mobile bomb can be used to kill many fish at once.
🎯 Jackpot Fishing
Killing a special boss fish can trigger the jackpot — the excitement of a big reward.
Shot Cost Management Tips
- Start at a low cannon level and increase it gradually
- Shoot at groups of fish — higher chance of hitting multiple fish at once
- Keep your balance by not spending too many shots on boss fish
- Set a shot budget for each session in advance

Bankroll Management Guide
Smart players do not just pick good games — they also manage their money wisely. Bankroll management is the most effective way to keep enjoying the game over the long term.
- Set a budget: Decide in advance how much you can spend on games each week or month. Set a limit that, even if lost entirely, will not affect your daily life.
- Divide into sessions: Split your total budget into smaller sessions. For example, dividing a ৳2,000 weekly budget into 4 sessions of ৳500 each makes it easier to stay in control during every session.
- The 1–5% rule per bet: It is wise not to spend more than 1% to 5% of a session's balance on any single bet. This reduces the risk of running through your balance too quickly.
- Stop after a win: After a big win, withdraw some of the profit. Not putting all your winnings straight back into bets is a healthy habit.
- Take a break after a loss: Stop when you reach your session limit. Placing more bets to recover losses often makes the situation worse.
- Keep a record of your play: Review how much you have won or lost in each game from time to time. This helps you make better decisions.
