This museum contains an intriguing collection of puzzles and games made by local and international artists. One puzzle requires 56,831 movements to complete, says curator Zandraa Tumen-Ulzii. There are dozens of handmade chess sets and ingenious traditional Mongolian puzzles that are distant cousins to Rubik's Cube. An enthusiastic guide will show you how the puzzles operate and will even perform magic tricks. A fascinating place for both kids and adults.

　　The museum is located in eastern UB, in a hard-to-spot building hidden behind an abandoned circular building that appears to have suffered a fire at some point. No photography.
