TraceLine: One Line Puzzle

TraceLine is a one line puzzle set in a moonlit grove of numbered runes. Draw a single unbroken path that visits every rune in order and covers every open stone exactly once, then watch the lanternvine light up behind your finger. ONE LINE PUZZLE RULES • Start at rune one and drag. The line grows cell by cell, never diagonally. • Every rune must be taken in numerical order, and every open stone must be covered. • Drag backwards to retract. Nothing is ever lost, so there is no penalty for exploring. • Three stars for the cleanest route, fewer for a route that wanders. SIXTY HAND-TUNED GROVES • Four worlds — Mosswake, the fen, the Sapstone floor and the Lanternroot Crown. • Boards grow from a gentle 4x4 into dense grids split by old roots you cannot cross. • Every grid is solved and checked before it ships, so each path puzzle has a real answer waiting. • Blocked stones turn late groves into a shape you work out rather than guess. OFFLINE PATH PUZZLE — NO WIFI NEEDED • The whole game runs on your device. No account, no sign-up, no connection. • Play on a plane, on the underground, or anywhere the signal drops. • Your progress is stored locally and never leaves the phone. There are no ads, in-app purchases or accounts. A QUIET BRAIN TEASER • No timers, no move limits and no streak you can break by putting the phone down. • Retract and redraw as often as you like — the grove waits. • Earn motes for clean clears and spend them on vine colours and small helpers. • Daily groves and honours give you a reason to come back without nagging you to. PLAY YOUR WAY • High-contrast rune plates for easier reading. • Optional grid guides that make long routes simpler to trace. • A calm-motion setting that damps ambient drift and entrance animations. • A confirm step before a half-drawn line gets wiped. TraceLine is a logic puzzle you can pick up for one grove or lose an hour to. The lanternvine is dark, the runes are waiting, and there is exactly one line that wakes them.
