How to Read Odds
Decimal Odds
Decimal odds are the simplest format. Multiply the odds by your bet amount to get the total return.
Total return = ৳500 × 1.80 = ৳900
(That means a profit of ৳400)
To find the implied probability, divide 1 by the odds. The implied probability for odds of 1.80 is approximately 55.6%.
Comparison of Other Formats
| Format | Value | Meaning |
|---|---|---|
| Decimal | 1.80 | ৳180 returned on a ৳100 bet |
| Fractional | 4/5 | ৳4 profit on a ৳5 bet |
| American | -125 | ৳100 profit on a ৳125 bet |
ko777 generally uses decimal odds — the most straightforward format for bettors in Bangladesh.
RTP and House Edge Explained
RTP (Return to Player) is the percentage of wagered money that a game returns to players over the long term. For example, a 96% RTP means that for every ৳100 bet, an average of ৳96 is returned to players. This is a statistical average, not a guarantee.
House edge is the other side of RTP — it is the casino's long-term mathematical advantage on every bet. A 96% RTP means a 4% house edge. This rate varies across different games:
- Slots: Typically 92%–98% RTP (house edge 2%–8%)
- Blackjack: Around 99% RTP or more with correct strategy (house edge approximately 1%)
- Roulette: Approximately 97.3% RTP for European roulette, slightly lower for American roulette
- Baccarat: Approximately 98.9% RTP on banker bets — one of the best among live casino games
Knowing a game's RTP before you play helps you make informed decisions. Keep in mind that RTP is a long-term average — results within a single session can go up or down. Choosing a higher RTP game means you can generally play longer on the same budget.
Volatility or variance is another important factor. High-volatility games pay out less frequently but in larger amounts. Low-volatility games pay out smaller wins more often. Choose the right game based on your budget and playing style.

Bankroll Management Guide
Planning your budget before playing is the key to an enjoyable experience in the long run. Follow the tips below:
-
Set a budget: Before each session, decide on a fixed amount that you can afford to lose without it affecting your daily life.
-
Divide into sessions: Split your total budget into smaller sessions. It is wise not to spend the entire budget in a single session.
-
The 1–5% rule per bet: Spend no more than 1% to 5% of your total bankroll on a single bet — this is the best way to control risk.
-
Stop after a big win: When you hit a big win, set a target for yourself and stop playing for the day once you reach it.
-
Respect your loss limit: End the session when you reach your pre-set loss limit. Placing more bets to recover losses generally leads to even greater losses.
-
Keep a record of your play: Track how much you won or lost in each game. This helps you understand your own patterns and make better decisions in the future.
