Parity · Ninefold Walk
Walk a copper cursor across nine numbered tiles. Every arrival adds one on pale squares or subtracts one on dark squares: find a route that makes all nine numbers equal. All 100 original Parity studies, including 50 signed-tile puzzles; no timer, unlimited undo/restart, known-route nudges, keyboard and visible pointer controls, device-local completion journal. Original authored boards and Board.js rules ported to native DOM with a responsive quiet-green interface. Ads, external fonts, social SDKs and cookie tracking removed.
