RTP and House Edge Explained
RTP (Return to Player) is the percentage of total bets returned to players over the long term in a game. For example, if a game's RTP is 96%, there is theoretically a chance of ৳96 coming back for every ৳100 wagered. However, this is a mathematical average — the result of each session can vary.
The RTP ranges typically seen across different game types are: slot games generally 92%–98%, blackjack around 99%, roulette between 94%–97%. These figures are general guidelines — check the information page of a specific game for its RTP.
House edge is the flip side of RTP — the casino's mathematical advantage. If RTP is 96%, the house edge is 4%. It is wise to check the RTP before choosing a game; a relatively higher RTP means less potential loss over time.
Remember — RTP is a long-term figure. Any outcome is possible in a short session. So RTP is just a helpful guide for choosing a game, not the whole story.
Football Betting
Football is very popular in Bangladesh and at 399app you can bet on all major leagues including the English Premier League, La Liga, UEFA Champions League and World Cup qualifiers.
1X2 Market
Choose from three options — the home team wins, a draw, or the away team wins.
Double Chance
Cover two possible outcomes — a convenient way to bet with reduced risk.
Over/Under Goals
Bet on whether the total goals in a match will be more or less than a specified number.
Both Teams to Score
Will both teams score or not — a simple yes/no betting market.
Asian Handicap
This special market levels the playing field by adjusting for the difference in team strength.
Live In-Play
Change your bets and place new ones in real time while the match is in progress.
Note: Many major European league matches kick off between 1:30 AM and 4:00 AM Bangladesh Standard Time (BST).
Fishing and Arcade Games
Fish shooting games are very popular among players in Bangladesh. In games from JILI such as Mega Fishing, Jackpot Fishing, Bombing Fishing and more, you shoot at fish swimming across the screen. Multipliers vary by the size and type of fish — smaller fish die more frequently, while catching a big boss fish earns a huge reward.
Upgrading your cannon level increases the cost per shot but also increases your ability to catch bigger fish. Start with a lower-power cannon to build experience. When a boss fish appears everyone targets it at once — be careful not to waste too many shots.
Arcade Game Types
- Dinosaur simulator game — tests quick reflexes
- Spin-the-wheel type — simple luck-based gameplay
- Popping bubbles and shooting gallery style games
- Scratch card and instant prize games
Pro Tip: Track the cost per shot. Dividing your session budget by the shot cost before you play makes it easier to stay in control.
Payment Methods and Processing Times
Deposits and withdrawals at 399app are fully secure and fast. See the table below for details on all methods.
| Method | Minimum deposit | Minimum Withdrawal | Processing Time | Fee |

| bKash (bKash) | ৳300 | ৳800 | Instant / 15 min–2 hours | Free |
| Nagad (Nagad) | ৳300 | ৳800 | Instant / 15 min–2 hours | Free |
| Rocket (Rocket) | ৳300 | ৳800 | Instant / 15 min–2 hours | Free |
| Upay (Upay) | ৳300 | ৳800 | Instant / 15 min–2 hours | Free |
| Bank Transfer | ৳300 | ৳800 | 1–24 hours | Depends on bank |

How to Read Odds
Understanding betting odds is an essential skill for any player. 399app primarily uses decimal odds.
Decimal Odds Example
You bet ৳500 and the odds are 1.80. If you win, you get: ৳500 × 1.80 = ৳900 (net profit ৳400).
Implied probability is the method of calculating the chance of winning from the odds. For odds of 1.80: 1 ÷ 1.80 = 55.6% — meaning the bookmaker believes this team has roughly a 56% chance of winning.
| Format | Example | Meaning |
|---|---|---|
| Decimal | 1.80 | ৳180 return on a ৳100 bet |
| Fractional | 4/5 | ৳4 profit on a ৳5 bet |
| American | -125 | ৳100 profit on a ৳125 bet |

Bankroll Management Guide
Bankroll management is the most important skill for keeping any gaming experience enjoyable and in control. It's not complicated — just follow a few simple rules.
Set a monthly budget
Set aside a fixed portion of your monthly income as your entertainment budget. Make sure that losing this amount will not affect your daily life.
Divide into sessions
Split your monthly budget into smaller sessions. For example, with a ৳3,000 budget you could have 10 sessions of ৳300–500 each. Instead of playing it all at once, enjoy it gradually.
The 1–5% rule per bet
Use between 1% and a maximum of 5% of your session bankroll on a single bet. This way, even on a bad run, your entire session won't end on one or two bets.
Set a win limit
End your session once you've won a set amount. Decide on a "win limit" in advance so you don't stake everything again in the excitement of winning.
Track your betting history
Note down your deposits, bets, and results for each session. Reviewing them at the end of the month makes it easier to understand your patterns and make better decisions going forward.
