Every shape, one single line.
A puzzle nearly three centuries old: trace every level in one line, never retracing a path. Graph theory, zen vibes, 200 challenges to solve at your own pace.
A logic game, not a reflex game
No countdown pressuring you, no lives to lose. Nodelight rewards thinking and observation over speed: look at the graph, find the path, let the solution come to you.
Real math, made playable
Nodelight revisits one of the oldest logic puzzles there is — popularized by the Seven Bridges of Königsberg problem that gave birth to graph theory nearly three centuries ago.
- 200 hand-crafted levels — triangles, stars, grids, prisms, crowns, bowties, and more.
- Real named graphs for the math-curious: Petersen, Nauru, Pappus, Desargues, Heawood.
- Eulerian paths — every level has a mathematically guaranteed solution to find.
Beat your records, at your own pace
Every level keeps your best time. Replay levels you've already cleared to shave off that last second. Levels unlock as you progress — or unlock any level early with a short, entirely optional rewarded video.
Built to unwind
An animated neon space backdrop, glowing lines, and a clean interface with no clutter. No forced ads, no account to create, no purchase required to play.
