Robot Odyssey DOS Game Online

This is one of the most original puzzle games ever designed, and my most favorite Apple II game. The objective here is to escape from Robotropolis, a dangerous underground robotic city. To escape, you have to program your robots to solve various mind-bending logic puzzles. The game also has one of the best on-line tutorials I've ever seen in a game. It is in some ways like the programming puzzle in Sierra's Castle of Dr. Brain, only ten times more fun-- and difficult. There is IMHO no better way to learn mathematical logic than this game :)
