Online game sessions

Pou handles online multiplayer using "game sessions". The game session is managed by the client, and when it gets modified, it is sent to the Pou game server to update the status of the session. Currently, only two games support this mode: Four Pous and Tic Tac Pou.

Internal workings

Game sessions are structured using a string with a chain of numbers representing a table split in rows and columns. The chain is read as squares of the table from left to right, and top to bottom.

Each square has a numeric value which shows if the square is empty (with value 0) or occupied by the client or the opponent. The player who creates the session gets assigned the value 1, and the opponent has the number 2.
