Game Rules:

1.
Players may shoot from any direction but must ALWAYS keep hand outside the ring, unless, see Rule 2.

2.
If a player knocks out the opponent's marble out of the ring and their shooter marble stays inside the ring, the player may continue their turn from where the shooter marble lands. Player's turn ends when the shooter marble is shot out of the ring or fails to shoot out any other of opponent's marbles. 

3.
Player that shoots out their own marble by accident, loses their turn and shot out marble now belongs to opponent. If player also shoots out opponent's marble, during this same turn, they can still keep opponent's marble.

4.
If a player fails to shoot out any marbles during their first turn shot and the shooter marble lands inside the ring, the player loses the turn and that marble stays until it's that player's turn again. If that shooter marble is knocked out by another player, during this turn, all collected marbles from the player of the marble that landed inside the ring are returned to the center. 

Shoot out all of your opponent's Marbles first. Win!
