I also suggesting luddo game . 1v1 or 4v4 what ever you want you can play this with multiplayer there was also one more game carrom bar pool . I think after including those games Gamblers will more attractive on that site . Because as the others boring games of casino those two are more enjoyable game .
One of the only issues I see when comes to your idea is the source of renevue for the casino itself.
How exactly would the house earn money from the luddo matches?
One option it could be to charge a fixed amount to each player the join the match/table and the winner keeps around 80-90% of that money from the others players (their foes) while the casino keeps the rest 20%-10%.
I am personally not sure how attractive this idea would be for the gamblers and the casino, though.
I dont know about luddo games but i did make out some research on what it is and find this one.
How to play LudoSo this is some other board games which is totally that time consuming and honestly its a boring one.

10% commission for every game isnt something that you could see or its really high which is one of the thing
that make people do lost interest.
