This isn't the one that I'm looking for, what I mean is that any chess player can play and do a PVP style of game but to join a matchmaking, they need to put a certain amount for example, you and me will each put a 0.005 btc and the total pool would be 0.01 and whoever wins between us will be getting the pot and Coinplay isn't that, it's just betting on professionals and grandmasters.
Oh, sorry, so it's a PvP style of playing, perhaps you might have to look at online tournaments to make a bet?
@Wapfika - wasn't aware of that casino has a bad reputation here, my bad.
Perhaps chess, although for some might not be sports, and because of that, it's going to be hard for what the OP is looking for, just saying. And if you play against AI based, then it might be hard to bet them or even score a draw.
