@hafiz786, I think book of ra 2 is also a slot game. Well, I think poker is also a best one game.
@banned0287822 there is really no definite way for anyone to tell which is the Best Game on OC.
Because there is no list of most used games. Now the only way that OC has right now is the Voting system and like everyone else Book of Rah 2 has the most so far.
There are various games. Many people like Card games, and many like Slots games.
