The game involves a series of slidable tiles, each bearing a pattern of
tracks. On the right hand side of the screen is an indicator showing a series
of coloured balls and three coloured cups. The balls will appear on the left
hand side of the screen in the order they are shown.
The object of the game is to catch the balls as they appear and direct them,
by using the tiles, into the correspondingly coloured cups on the right. The
balls will always follow the available path but should a ball fall into a black
area outside a tile then it will be lost. You can only move a tile that is in a
position to be moved, that is, next to a blank space. You can move a tile while
the ball is moving through it. The tiles can be moved up, down, left or right
and they can be rotated.
