How to play Reversi...

The objective is to have the most pawns at the end of the part.

To each turn, you place a pawn of your color on an empty space. You can place a pawn only at the places where you capture at least one of those of your adversary.
You capture one or more pawns of your adversary if they are between one of your pawns and that which you pose on the plate.
You can capture in the eight directions at the same time - to the top, towards bottom, on the right, on the left, in the four diagonals.
