A player can not play twice. If the boxes of the opponent are all empty, the player must, if possible, choose a shot that replace at least one seed in the enemy camp.
END OF THE GAME :
The game ends if :
1 - A player can not play because he no longer has seed in his camp (his opponent was unable to move him back earlier). His opponent gets the seed that remains.
2 - It is clear that another taken is impossible, the same positions successive indefinitely. Each player gets the seeds of his camp.
3 - A player captures 25 seeds (more than half, we can stop the game), he is the winner.
