Matchbook Equation Lab

Matchbook Equation Lab is a portrait matchstick logic workshop set inside a miniature typesetting theatre. Press a lit match, drag it to an empty groove, and repair the equation without adding or removing any wood.

Thirty authored puzzles progress through five foldout matchbooks: simple digit repairs, cross-symbol transfers, two-digit totals, two-move challenges, and final mixed calibrations. Every level is free to enter and replay. Undo and reset are always free. Optional coin hints reveal the next exact transfer, while clearly labeled rewarded AD entries grant coins only after a successful reward. Earn three stars by repairing the equation, meeting its minimum move count, and solving without a hint.
