You can play against a human opponent or against the computer: You shoot the puck to the other side trying to score a goal. When you hit one of the E's in the middle the puck changes direction, making it more difficult for your opponent to stop the puck. Maybe it was from this game on that the Mario & Donkey Kong idea was being used to an annoying degree. Like all micro vs. system games it is quite difficult & boring, beautiful design though.
