About Magnesium 173

Magnesium 173 is a puzzle game built around branching puzzles and strange rules inspired by quantum mechanics. Through these rules, it explores the question of what makes a choice meaningful. Its more than 100 puzzles are simple to execute but challenging because of the ideas and consequences behind their mechanics.

Puzzle design

Each puzzle presents a new idea, examines it and twists it; there are no filler puzzles. The puzzles are honed to keep their difficulty in discovering what the mechanics imply, rather than in their size or complexity. Hints point you in the right direction when you get stuck, and step-by-step solutions are available if you need more help.

Sound and accessibility

The game features an original soundtrack by Ian William Craig and is designed to be color-blind friendly.
