The 3% Rule: A Logic Puzzle That Hides Three Exceptions

Why it surfaced

The site turns “spot the difference” into a more exacting game: first decode the rule, then identify all three anomalies. Its companion experience offers a clue, the rule, and finally the answer, while the larger project promises 100 puzzles built around visual systems, number logic, and relationships.

A playable logic-puzzle system where 97 elements follow a hidden rule and three break it.
