You and the AI each control a flying saucer and are competing to earn the most points.
Valuable triangles float in from the edge of the screen and collecting them gives you points.
A few rules make things tricky:
1. Triangles start small and worth one point, but can grow into larger ones worth five points, so wait before collecting them, without letting the AI beat you to it.
2. Triangles come in three colours, and your points in each colour are kept seperate. At the end of the game your score is your weakest colour, so try to collect a balance of colours, and try to keep the AI away from the colour it needs.
3. If the saucers ever collide with each other, the one that was traveling slower gains three points in each colour, so be careful!
