Probability 0 will definitely have you at your wits end. The game is a downward platform game that surprisingly has very little to do with probability but offers tons of options for you to experiment and explore. Levels of the game are randomly generated so you never get the same thing twice. Well, at least not all the time. The game was created by Droqen, a TIGForums member. The idea behind the game is that instead of a health bar, your status is represented by a number. You start off in the double digits and as you descend and fight off baddies; the number decreases. It goes down considerably if you take a hit. It's your job to stay alive, fight off the enemies and keep the number from hitting a zero. This simply means that your probability of staying alive is zilch. Give it a try, it's definitely worth your while.
