About this game

"The truth always lies in the smallest inconsistencies."

Can you spot the single lie based on the testimony and the circumstances at the scene?

This app is a fully-fledged mystery novel game that can be enjoyed in the space of a commuter train ride or the three minutes it takes for your instant noodle soup to be ready.

[Included Case Files (Partial)]
■CASE 1: The Grim Reaper Crawling on the Sand
A wealthy man dies mysteriously in a locked tent in the Egyptian desert. All that's left at the scene is a container of melted ice cream. No poison was detected, and no external injuries were found. What trick could the "invisible Grim Reaper" have used in this scorching desert?

■CASE 2: The Last Train of the Mist
A body is discovered at a station on the verge of closure. However, all the suspects have perfect alibis: they "heard the sound of an arriving train." Uncover this tragic "trick" that exploits dense fog, timetables, and human psychology.

■CASE 3: The Demon of Noon
A glass-walled villa on a remote island in the scorching heat. A gunshot rang out in an empty room in full view of everyone. Could the culprit be human...?
The equation for the perfect crime is now complete.

Now, the detective's chair is vacant. Why not turn your three minutes into an exquisite mystery experience?
