How to Play

1. Player one call function createGame passing the attached value, and send gameId to player 2
2. Player two call function joinGame(gameId) passing gameId that player one sent, also passing the attached value
3. Player one is the first to play, calling function play(gameId, lin, col) with gameId, lin, and col as argument
4. Player two continues the game
5. The plays continue until someone win, or the game gets draw
6. Players can view the board during the game, or after it end using function viewBoard(gameId) that gets gameId as parameter
7. When someone win, the attached deposit will be transfered to the wallet of the winner.
