Tribble

Tribble is an altered-gravity sport designed to be played by all beings. It is played in an enclosed, rectangular box-shaped field. The object of the game is to score more points than your opponents by successfully getting the ball through the goal.

The Tribble ball can expand and contract to three sizes by bouncing it on the field surface. The small-sized (red) ball is worth one point. The medium-sized (green) ball is worth three, and the large-sized (blue) ball is worth ten. The game ends when the large ball enters the goal or a team reaches ten or more points.
