Doodle Jump is an endless vertical platformer developed by Lima Sky. The game first appeared in 2009 and became widely recognized for its distinctive hand-drawn visual style and remarkably simple gameplay.

Instead of controlling when the character jumps, players focus entirely on movement. The Doodler automatically bounces whenever it reaches a platform Doodle Jump, so your main responsibility is to guide it left or right and make sure each landing is successful.

As the Doodler climbs, the screen continuously scrolls upward. New platforms, enemies, and obstacles enter the play area, forcing you to make quick decisions. There is no traditional finish line waiting at the top. Your run continues until you make a mistake, meaning the real objective is to survive as long as possible and achieve an impressive score.

This endless structure gives Doodle Jump its addictive quality. Even when a run ends, you immediately know that another attempt could take you higher.
