Two key concepts every new user should understand
- Odds
-
Odds are a numerical representation of the probability of an event occurring, and they determine how much you can potentially win on each bet.
Example: Odds of 2.0 mean a ৳100 bet returns ৳200 in total if you win.
- RTP (Return to Player)
-
RTP for slots and casino games indicates the average percentage of wagers players can expect to get back over the long run.
For example: a 96% RTP means that, on average, BDT 96 tends to be returned for every BDT 100 wagered.
