Out of moves
Drag a tile round to turn it — letting go is the move — or tap it for a quarter turn. Connect every pipe and light every bulb — that's the whole game. Stuck? Undo and Restart sit right under the board, and every puzzle is guaranteed solvable. Board size, wrap-around, hints and sound live under ⚙.
All controls & scoring
Mouse: drag a tile round and release (each quarter turn is one move; a half turn is two) · click a quarter turn · right-click the other way · middle-click lock a tile in place. Touch: drag to turn · tap a quarter turn (the ⟳/⟲ button sets the direction) · hold a tile to lock it. Keyboard: ← ↑ ↓ → move · Space rotate · Z the other way · L lock · Ctrl+Z undo · R restart · N new puzzle.
Stars are earned by moves: ★★★ within 2× par, ★★ within 3×, and an undo counts as one move. Beat the time target for a bonus ⚡ — the timer starts on your first move and pauses while the tab is hidden, and time never costs a star. In Journey the budget is hard: every level allows 4× par moves (★ within the budget), the strip above the board shows the stars and the ⚡ countdown live, and running out locks the board until you restart. Quick Play plays by the same rules on a board of your size; the Daily keeps stars and ⚡ with no cap, since it is the one board everyone compares. Faint red caps mark pipe ends that aren't connected yet. Turn on Wrap-around and the board becomes a loop: the top edge meets the bottom, the left meets the right, so nothing can point "off" the board. Your boards, records, and settings save locally, so refreshing resumes your game. Replay the intro any time with ⚙ → Tutorial.
