The Robot Odyssey is an 1984 educational game archive that requires you to know the basic programming principles to play.
It was a source of inspiration for the programmers of his time, and we would say that it also pushed the next generation to take up programming in general. You can either "remember the old" or test your programming, from your home computer and through your browser with a visit to robotodyssey.online website.
The game looks pretty simple: you have to escape Robotopolis with the help of three robots, which you will need to program by putting the right wiring to solve the puzzle.
David Auerbach, who writes about Slate, named it the most difficult computer game of all time, stating:
Let me just say: Every kid completing this game and if he's still a kid then ... is guaranteed a career as a software engineer. And any adult who can complete this game should become a computer engineer. Robot Odyssey is the toughest "educational" game ever made. It is also an amazing technical breakthrough and one of the most innovative games of the Apple IIe era.
Does it sound like a challenge? All you have to do is try.
