Numbers Reversi

Classic play is the game that introduced a trout score system into Reversi (Othello) of playing a game.
The total point of the put trout score of one's top (black) is finally score.
With Reversi (Othello), I leave white and a black top to a trout empty in turn,
It is changed into a-colored top of oneself when I catch the top that the partner is colored length and breadth diagonally in the frame of one's color and is a game.
