Puzzler Mind Gym 3D is a brain-training puzzle title released in 2011 for the Nintendo 3DS. Built around a structured 90-day program, it presents daily sessions of mental exercises across four categories: Memory, Word, Visual, and Numerical. Each session consists of four games drawn from these categories, which must be completed before unlocking that day's Mind Gym Challenge — a finale exercise overseen by Professor Ian Robertson, a neuroscientist specializing in cognitive rehabilitation. Players can follow the program sequentially or browse freely among any of the 90 sessions, selecting whichever category suits them. The game makes use of the 3DS hardware's stereoscopic display to present its puzzles in 3D. The overall design frames mental exercise as a daily routine, combining quiz and puzzle mechanics with a structured progression system aimed at improving practical cognitive skills.
