there are many options that open up opportunities to cheat in the chess game, I personally don't like it
maybe a game that relies on the right skill is billiards it will be very interesting
don't expect luck but skill
But if the chess game has each duration to think about then there is no time to look for cheating opportunities, but once chess will not attract gamblers to play because the game is long and only 2 players, popular gambling games are only slots, blackjack, dominoes, etc. . So other games are only alternatives to make gamblers not bored and have varied games.
Yes, chess requires a lot of time but if time can be fixed for them that would not be bad idea. Even though it is a long game, chess players will definitely be willing to gamble on it. But whether or not it is added is entirely up to the casino owner. They will definitely try to include if they think it can be profitable.
