How It Works
Simple Rules, Endless Challenge
Draw a connected path from 1 to N, passing through every cell exactly once. Navigate walls and hit waypoints along the way.

01
Draw Your Path
Click and drag to draw a continuous path across the grid, connecting numbers in order from 1 to N.

02
Fill Every Cell
Your path must pass through every single cell exactly once — no gaps and no revisits.

03
Hit the Waypoints
Some puzzles include waypoint markers that your path must pass through to count as solved.

04
Navigate Walls
Wall segments block certain cell borders, forcing you to think carefully about your route.
