Rule Hunter is an inductive-reasoning puzzle game — no formulas to memorize, just patterns to discover. You're shown numbers linked by arrows or shapes and must infer the hidden rule to fill in what's missing. Five difficulty tiers (Easy→Master) each introduce a new way of thinking, across 8 visual formats: chains, hexagons, pyramids, spirals, symbol equations, and more. Free, ad-supported for hints, no in-app purchases. For fans of Sudoku, Wordle, or Math Riddles.
