Description

1line Single-stroke routes, node order, clean backs Overview: Minimal brain-teaser where you draw a single continuous line to cover every edge once; success comes from spotting odd-degree nodes, planning entrances/exits, and using symmetric sweeps. How to Play As Expert (Mobile & Desktop): Goal: trace all segments in one stroke without lifting or retracing; hard packs add time/move limits. Controls: drag to draw • undo step • reset • hint (limited) • Mobile: large nodes with haptics. Modes/Levels: basic shapes, crossings, mirror packs, timed blitz, daily grid. Tips & Strategies: • Start at a node with an odd number of edges—ideally one of exactly two odds • Use bridges last so you can exit cleanly • Mirror shapes: trace one side, then reflect the motion • For lattices, “comb” across rows, then close with verticals • Leave tiny stubs for the end; don’t fill them mid-route • If stuck, undo to the last junction and choose the path you haven’t touched • Common mistake: crossing in the middle too early—reserve central edges for exits. Game's Troubleshooting: • Lines not snapping? Focus canvas/reset zoom • Stylus lag? Lower effects; cap 60 FPS • Hard to see lines? Enable high-contrast theme • Progress gone? Allow local storage • WebGL issue? Update drivers/enable acceleration. Similar Games You Might Like (curated): Knot Logic—order pulls; Switch Path—direction gates; Hook—sequence clarity.
