Chess, checkers and other board games are skill-based games that require tremendous amount of knowledge in order to perform significantly better against your opponents. As opposed to blackjack and poker, which are still considered as "skill-based" games in the realm of gambling, those two (2) platforms are incompatible within the same comparison.
Games like chess are not advisable to be featured on casinos or for gambling because it's strict on levels, they'll never be a way a player whose Elo is 1300 would win against an opponent with an Elo of 2000, unless they'll find a way to match gamers with approximately same Elo, skilled players will always lie about their rating just to win huge money. It happens in tournaments too, they're players who claim to have 700 Elo but did it just to take first position, while in real sense their playing rating is close to 1500.
