A puzzle game about discovery

Unknown
Fifty handcrafted puzzles where discovering the rules is part of the solution. Look closely, test your assumptions, and find the logic that was there all along.
No two puzzles think alike.
Move between logic, spatial, visual, word, mathematical, and discovery-based challenges. Each puzzle is individually designed; each asks you to see the problem differently.
Handcrafted variety
Fifty distinct puzzles explore patterns, motion, language, space, mathematics, and hidden systems.
Your pace, uninterrupted
No ads. No time limits. Play offline, step away, and return when a new idea finds you.
