Odds How to Read
Understanding betting odds is the first step to becoming a successful bettor
Decimal Odds: The simplest format. Your total return = stake × odds. For example, if you bet ৳500 at odds of 1.80 — you get ৳500 × 1.80 = ৳900 if you win (profit ৳400).
Implied Probability: The odds tell you how likely the bookmaker thinks an event is. Odds of 1.80 means roughly a 56% probability. Formula: 1 ÷ odds × 100.
Fractional Odds: The British format. 2/1 means ৳2 profit for every ৳1 staked. In decimal, this is 3.00.
American Odds (Moneyline): +150 means ৳150 profit on a ৳100 bet; –150 means ৳100 profit on a ৳150 bet. Bangladeshi platforms typically display odds in decimal format.

RTP and House Edge Explained
Know these important facts before you play
RTP (Return to Player) is the theoretical percentage of total bets a game returns to players over the long term. For example, a 96% RTP means an average of ৳96 is returned for every ৳100 wagered — but this is the average across millions of spins, not a guarantee for any single session.
Typical RTP ranges by game type: Slot Games generally fall between 92%–98% RTP; Blackjack can reach close to 99% with correct strategy; Roulette (European) is approximately 94%–97%; Baccarat is typically around 98.5%.
House Edge is the flip side of RTP — the percentage of total bets the casino retains over the long term. A 96% RTP means a 4% house edge. Playing games with a lower house edge means your balance lasts longer.
In practice, every spin or hand is completely independent and controlled by a Random Number Generator (RNG). Previous results have no effect on future results. So play responsibly and always stay within your set budget.
