If poker is included on what you search for may be you can try btcking. I know nowadays there is less of multiplayer games which is less attractive to because people can't use any strategy to win it. Btcking is pretty nice to play poker because they got bot too so you can easily get profit there
Poker is likely out of the question as it is something very common and for sure OP has already considered it. Since poker is very mainstream already and everybody knows it.
I would say that you can try those games found here on the forum like action-gamble which is a rock paper scissors kind of game. Not so sure how well it works as I only tried it once and if it will suit your taste.
