Unless you want to get robbed then play with this casino. Coinplay has an existing scam accusation and active flags for violation here against forum user that play in that casino. Playing in that casino is high risk so I hope you should retract this suggestion of scam site.

@OP I doubt that there’s a casino offering a pure skill based gambling games such as chess. Casino has a lot of profit from the typically luck based game like slots compared to a minimal fee on a chess game that consume longer time per round.
