Nodelight : Zen Puzzle
Every shape, one single line
Free · Designed for iPad. Not verified for macOS.
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.
Nodelight revisits one of the oldest logic puzzles there is: draw a whole shape without ever lifting your finger and without tracing the same line twice. A principle nearly three centuries old, popularized by the Seven Bridges of Konigsberg problem that gave birth to graph theory -- now turned into 200 neon, soothing, addictive puzzles.
HOW TO PLAY
Tap a point to start, then drag from point to point to trace the connections. You can pass through a point you've already visited, but each line only ever gets drawn once. No path left to take? The level restarts right away, no friction, no frustration -- you just try again, calmly.
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
Triangles, stars, grids, prisms, crowns, bowties... and genuine named graphs borrowed from graph theory (Petersen, Nauru, Pappus, Desargues, Heawood) for the math-curious. Every level is an Eulerian path waiting to be found, with difficulty that ramps up gently.
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; want to jump ahead or peek at a level further out? Unlock any level with a tap by watching a short rewarded ad, entirely optional.
A NEON MOOD, BUILT TO UNWIND
Animated space background, glowing lines, clean interface with no clutter: Nodelight is designed to be as much a calm pause as a challenge for the mind. No forced ads, no account to create, no purchase required to play.
A game for the five-minute wait as much as for the long session chasing a flawless run. One line at a time, mind at ease.
Tip for those who read all the way down here: count the lines coming out of each point. If it's an odd number, that's often the point you need to start from.
