How to Read Odds
Understanding odds before you start betting is essential. Read this guide and you will be able to read any odds with ease.
Decimal Odds
The most common format. Example: odds of 1.80 means a total return of ৳180 for every ৳100 bet.
Example: A ৳500 bet at odds of 1.80 gives a total return of ৳900 (profit ৳400).
Implied Probability
Work out the probability of winning from the odds: 1 ÷ odds × 100%. At odds of 1.80, the probability = 55.6%.
Bookmakers always build in a margin, so the sum of all implied probabilities adds up to more than 100%.
Other Formats
Fractional (British): 4/5 means a profit of ৳4 on a ৳5 bet.
American (Money Line): -110 means you need to bet ৳110 to win ৳100 profit; +130 means a ৳100 bet returns ৳130 profit.
Quick Reference Table
| Decimal | Fractional | American | Implied % |
|---|---|---|---|
| 1.50 | 1/2 | -200 | 66.7% |
| 1.80 | 4/5 | -125 | 55.6% |
| 2.00 | 1/1 | +100 | 50.0% |
| 2.50 | 3/2 | +150 | 40.0% |
| 3.00 | 2/1 | +200 | 33.3% |
What Are RTP and House Edge?
What Is RTP?
RTP, or "Return to Player", is a percentage that tells you how much of the total amount wagered a game returns to players over the long run. For example, a 96% RTP means the game returns an average of ৳96 for every ৳100 bet. However, this is an average across millions of rounds — results in any single session can vary.
RTP is purely a theoretical figure — it is not a guarantee that you will get back that amount in every session. In the short term, variance or volatility can cause wins and losses to fluctuate considerably.
What Is House Edge?
House edge is the flip side of RTP — it is the average amount the casino keeps from each bet over the long run. If a game has an RTP of 97%, the house edge is 3%. This difference is the foundation of the casino's business model.
Understanding house edge lets you see which games carry less risk and where it is reasonable to spend more time and budget.
Typical RTP Ranges for Various Games
- Slot Games: typically 92% – 98%
- Blackjack: up to ~99% with correct strategy
- Roulette (European): ~97.3%
- Baccarat: ~98.7% (on the Banker bet)
- Video Poker: 95% – 99.5%
A high RTP does not always guarantee a win. A game's volatility or variance is equally important.
Why Does This Matter?
Knowing RTP and house edge lets you choose games more wisely. Picking games with a higher RTP means a greater chance of enjoying longer entertainment.
The most important point, however, is this: online gaming is for entertainment, not as a source of income. Always play within a set budget and do not assume a win is guaranteed. 77b7 places responsible gaming as its highest priority.
