Made for curious minds.

A little discovery, every day.

Deductidle is a free puzzle game. Each day brings three stages drawn from words, numbers, shapes, emoji and cards. The fun is in testing an idea and spotting the rule that connects the clues.

No timer and no account required. Take your time, ask for a hint, and come back tomorrow.
