To play the game, a player has a bundle of these katoka in his possession. The bundle is thrown in the air and as the others fall down the player would have to try to catch one or two on the back of their palm as they fell back down toward the ground. It is similar to knuckle bones in that it is a game to help build hand-eye coordination. Then again, catching one or two in each hand. The one or two rule is set at the beginning of the game. Participants would play until the whole bundle had caught.
