Gameplay consists of four individual robots, or “machines”, trying to collect tennis balls, or “treasure”, into their own home base.

The four home bases measure 20 inches (50.8 cm) square and one is placed at the center of each of the four edges of the field.

The center post is 12 inches (30.5 cm) tall and is capped by a high-value tennis ball worth 25 points.

The remaining two corner posts are 24 inches (61 cm) tall and capped by medium-value tennis balls worth 10 points.

To score, robots must remove tennis balls from the posts or retrieve them from the floor and place them into their home base.
