Buggy

Buggy presents the player with seven math problems where the computer incorrectly calculates something. The player can ask the computer to solve certain equations in order to try and find out what the "bug" is. When the player thinks they have figured out what's wrong, they can challenge the computer. At this point the computer presents an equation and the player must predict the incorrect outcome the computer will give.

The player starts with 100 points and with each equation or try points are subtracted from the total. The aim of course is to score as many points as possible.
