Gamers love a good challenge. Unless it involves an underwater level. Or a mine cart. Or pretty much anything from Mega Man 9. Come to think of it, gamers are frustrated by a lot of things. Here's a tribute to the levels that made us collectively break our controllers.

1. Battle Toads: Turbo Tunnel

The most annoying level of the Citizen Kane of near-impossible video games, the BattleToads speederbike level is the reason why the Game Genie and adderall were invented. Nothing short of John Nash-like spatial recognition is enough, as even thousands of plays can still leave the most talented of gamers in the fetal position. What sets it apart from other classic videogames, and what is perhaps its most annoying quality, is that years later it still retains the same level of difficulty it had when you were 9.
