10 Video Games Nobody Has Beaten (Because It's Genuinely Impossible)

We're getting really particular with this one but it's such an incredible example that needs to be included. Most people would assume "finishing" a Mario Party title would simply include grabbing all the unlockables and perhaps setting some high scores, but in Mario Party 4 it's impossible to actually get to the end of one particular mini-game.

Doors of Doom is a single-player mini-game which is as simple as it gets. The player is presented with two doors, with a 50% chance of proceeding to the next room and a 50% chance of being stopped by Bowser. There's no one to beat, it's about getting through as many doors as possible. However, that 50/50 split gets more tense every time.

On the one hand, there's no actual victory but there is an end-point. At 30 doors opened, the next will always be Bowser - a hardcoded limit in the game. However, there's no recording of anyone ever legitimately getting this far. The current world record is a total of 14 doors, not even half.

If you want to get mathematical about things, that's where the real juice is. Because each room has a 50% chance of success, doing this 30 times makes for astronomical odds. It's calculated that the possibility of getting to the game's hardcoded end is 0.00000009%. That's 1 in less than a billion.

This isn't a party, this is a nightmare.
