"SX'Reversi" is a Reversi game (also known as Othello) where the goal of the game is to complete the grid with more tokens of your colour than the colour of your opponent.
The game ends when the grid is filled or when players can't put a token any more.
Each player can play by turns, if possible, otherwise the player standing in the situation where he can't place a token must pass his turn.
In order to put a token, the player must capture one or more tokens of the opposing colour. The captured tokens will take the colour of the player.
To capture opponent tokens, the player must surround a opponent token line (horizontally, vertically or diagonally). In other words a token line is surrounded if there is on each extremities a token of the opposite colour.
