Monkey Brains is a 2001 puzzle video game developed by Yobro productions for PC.

The game follows injured scientist Dr. Simius who attempts to stop the evil Dr. Kreep from using mind-control technology.

Levels are presented from a side-scrolling view, with Dr. Simius controlling a group of monkeys who must perform tasks like pulling levers and pressing buttons while evading traps and enemies in order to progress to the next level.

The graphics and sound are adequate, many of the levels and puzzles can be entertaining, and the game mechanics add a bit of a twist.
