Small rules. Plenty to master.
Color Foundry is a tactile spatial puzzle about changing the board without trapping your next move. Slide, rotate, stack, or connect pieces until the whole system clicks into place. A compact ruleset opens into deeper mastery through changing constraints and board states. Its identity comes from a distinctive objective and rule twist rather than a cosmetic reskin. A typical session lasts three to eight minutes, works comfortably with touch or keyboard, and saves progress without requiring an account.
