10 Worst Levels In Super Mario History
9. World 6-3 - Super Mario Bros.

Since Super Mario Bros. is the most celebrated video game of all time, scrutinising Nintendo's magnum opus seems somewhat blasphemous.
It wasn't just a successful game; it caused the western world to recover from The Great North American Crash, made Nintendo a household name, and created the most recognisable video game character in history.
For its time, Super Mario Bros. was pretty much perfect... except for one level that's surprisingly lazy. In World 6-3, you have to jump on several tall platforms and scale-lifts, reach the flagpole and...eh, that's pretty much it. There are so few obstacles, you can complete the course in 30 seconds.
Not only is the stage short, it is insultingly easy since it consists of a single baddie, Bullet Bill. Bill will appear on one side of the screen and try to hit you. Every time he disappears, he'll respawn and try again.
Apart from falling between the platforms, Bill is the only threat that World 6-3 poses. I'm sure it was gruelling to create such a game during the 1980s, but surely it wouldn't have been too taxing for Nintendo to chuck in a few Koopa Troopas or Buzzy Beetles here and there.
