The way to play with Bidama (glass marble balls) differs from one locality to another. In one basic version of the game, players draw a square (or a triangle) on the ground. The leading player puts his marble inside the square. Then the opponent player tries to knock the marble out of the square with his own marble. If it shoots the target marble rightly, he will win it, but in return for this, his marble is in the position to be shot. Another version involves digging several holes in the ground. The players take turns flipping their own marbles to shoot the holes according to the designated route. It is possible to add various optional rules to the play, for example, when a player mistakenly shoots another player’s marble on the way, this will carry some penalty. Or the player who reached the goal first will be given the right to hit his marble against another one and so on.
