Players in this casino compete against each others in games such as Ludo, Poker, Rummy, etc... .
In this type of casino, players rely on their luck and skills to make a profit.
I'll go with option B, because in playing with people, i have a certain level of assurance in my heart that the game is a fair game where the luckiest and most skillful amongst the contestants wins. Also knowing that an individual like me who maybe needs the earnings from the gamble more than i do has won it, rather than the house that has won alot of people's money will console me.
I did feel the same when I was actively playing in some poker sites. I felt the game is fair more than provably fair game, but in fact it is not true since there is no provably fair system on the poker sites that I used to play. There were also many poker sites cheat their players by pretending to be players to play against real players while they knows all the cards own by all players so it gives them bigger winning chance.
The point is, not all games where you play against other player is fair especially if you play in online casino unless the casino is implementing a provably fair system where every single round of the games can be verified.
