Atamania (アタマニア) is a series of casual puzzle video games published by Level-5. The series comprises two, unrelated series of puzzle games. Tago Akira no Atama no Taisō (多湖輝の頭の体操, Professor Tago's Mental Gymnastics) is a collection of puzzles created by Akira Tago, a Japanese professor who has authored a series of books within Japan under the same name. Players read through stories and solve puzzles at their own leisure. Surōn to Makuhēru no Nazo no Sutōrī (スローンとマクヘールの謎の物語, Paul Sloane and Des MacHale's Intriguing Tales) is based on the concept of lateral thinking puzzles, books authored by Paul Sloane and Des MacHale. The games have drawn comparison to the Professor Layton series, which is also published by Level-5.
