What is "atamania"

is a series of casual puzzle video games published by Level-5. The series comprises two, unrelated series of puzzle games. 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. 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.

A third branch of the series, entitled Mystery Room, was also planned, but the title was ultimately rebranded as a spin-off of the Professor Layton series, entitled Layton Brothers: Mystery Room. Level-5 CEO Akihiro Hino stated in 2008 that more Atamania titles were under consideration, but aside from Mystery Room, none have since been announced.
