50m

50m is the second level of Donkey Kong. The aim of this level is the same as the previous level, however it is harder to do so. This level has a series of conveyor belts which run along the the second and third and forth floors. This level still has hammers to smash Trouble Bug (there is no barrels on this level). with, there is also still ladders of which Jumpman must climb.

The oil drum in this level is in the middle of the level is appose to the beginning making it more likly to be burnt by a Trouble Bug. This level is also made harder than the first because the top ladders will be disconnect and connect when Donkey Kong beats his chest which he does instead of throwing barrels. Also because the top floor is a conveyor belt Donkey Kong will be moving from left to right.

As Jumpman reaches the top, Donkey Kong will take Pauline agian and will climb up to the next level, which is 75m.

Trivia

 * This level was removed from NES version due to a memory limit.
 * This is the only level of which Donkey Kong's action doesn't make something appear (25m makes barrels; 75m makes springs; 100m makes Trouble Bugs).
 * This is also the only level where Donkey Kong moves, though technically it is the conveyor belts which are moving.
