omg wht about a table
the table has a game board like thing
the game is tic tac toe so tht its keep it as simple as possible
u could bet money with a max set amount to stop scammers

the game rules

its a game for two players, X and O, they each take turns marking the spaces in a 3×3 grid. The X player usually goes first. The player who succeeds in placing three respective marks in a horizontal, vertical, or diagonal row wins the game.

this could be for a guild house or house item
