Every board is a dead circuit. One node is live. Turn the pieces until the current reaches all of them. It sounds simple, and the first boards are. Then the grid grows, and you start reading the board instead of guessing at it: a piece on the edge can't point outward. A corner has only two ways to face. Follow those constraints far enough and the whole solution falls out — no luck, no countdown, no penalty for thinking. • ONE RULE — every node connected, nothing left dangling • PURE DEDUCTION — every board is solvable by reasoning alone • PAR SCORING — clear a board in the fewest turns for a PERFECT • FIRST 20 BOARDS FREE — unlock unlimited play with a one-time in-app purchase • OPTIONAL TIPS — support the developer from Settings • ENDLESS AFTER UNLOCKING — fresh boards, with completed levels replayable from History • CORE GAMEPLAY OFFLINE — no account needed to play • GLOBAL LEADERBOARD — optional Apple or Google sign-in; your latest level result counts • DAILY CIRCUIT — one shared daily puzzle with a limited ranking opportunity • NO ADS OR ANALYTICS — a chosen nickname and scores are used for the optional leaderboard Quiet, slow, and difficult in the way a good puzzle is difficult.
