You have reached the System Puzzle! In this game, it will be up to you to restore the functionality of the system by plugging the holes that the virus has caused within it. Try serving as your own sort of virus protection software. After you have ensured that each piece of the puzzle is in its correct location, insert the plug, and go to the next challenge! There are hundreds of difficult stages, each one more challenging than the one before. Because the user interface is so elegantly built, and the noises are so lively, you won't grow tired of playing them very quickly!
