How to Read Odds
Understanding odds before you start betting is essential. Odds tell you how much you will get back relative to your bet, and how likely that outcome is.
Decimal Odds
The simplest method. Multiply your bet by the odds:
Example: ৳500 × 1.80 = ৳900 returned (profit ৳400)
The higher the odds, the lower the chance of winning but the greater the reward.
Implied Probability
Easily work out the probability from the odds: 1 ÷ odds × 100%
Odds of 1.80 means 1 ÷ 1.80 × 100 = approximately 55.6% probability.
Comparing Other Formats
| Format | Example | 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 |
RTP and House Edge Explained
Before playing any casino game, it's important to understand RTP and house edge. This will help you make informed decisions.
What is RTP (Return to Player)?
RTP is the theoretical percentage of total bets that a game returns to players over the long term. Example: a 96% RTP means an average of ৳96 comes back for every ৳100 bet.
Typical RTP Ranges by Game Type
| Game Type | Typical RTP Range |
|---|---|
| Slots | 92% – 98% |
| Blackjack | Approximately 99% |
| Roulette | 94% – 97% |
| Baccarat | Approximately 98.9% |
What is House Edge?
House edge = 100% − RTP. It is the casino's long-term mathematical advantage. A higher RTP means a lower house edge. Keep in mind — RTP is a mathematical average; the outcome of each session is completely random.
Crash Games
A crash game is a fast-paced multiplier game where a plane (or rocket) flies upward and the multiplier keeps rising — but it can crash at any moment.
How a Round Works
Place your bet before the round starts. As the multiplier rises, you can press the Cash Out button at any time to lock in your winnings. If you do not cash out before the crash, your entire bet is lost.
Aviator — Spribe's Popular Crash Game
Aviator is currently one of the most well-known crash games in the world. Using the auto cash out feature, you can automatically cash out at a set multiplier.
Warning: Each round in a crash game ends very quickly. Set a stop limit before you play and do not exceed it. Do not trust any "prediction" or "signal" software — every round is completely random.
