Balls typically have numbers all over their outer edges. The numbers on balls used in number lottery games (except the 2D Lotto), are read on the spot without the need of touching them. In the digit lottery games and the 2D Lotto with top drawing Mega Gems, the balls are adjusted to clearly show the numbers drawn. Because of the nature of the Power Lotto Mega Gem, each of the methods mentioned were applied in each of the machine's two chambers.
