The object here is to eliminate as many Smiletris as possible. You do this by moving the falling Smiletris so that they match those already fallen. When two of more Smiletris of the same pattern stack up,the pile cracks. If still another Smiletris of the same pattern lands on it,they all disapper. The more Smiletris you eliminate,the more types of patterns fall.
Operation is simple.
Your snake has to eat all of the apples faster than the computer's snakes. You,the player,are a snake on an empty stomatch and race against the computer's snakes trying to eat as many apples as you can. When all of the apples have been eaten, a hole opens in the wall for you to escape through. Making it into the hole raises you to the next level. All operations are done with the cursor keys.
