How to play

Draw a line from start to finish. That's it, and then it gets interesting.

The basics

1. Press on the green dot and drag. Your line follows through open halls and stops at walls.
2. Reach the gold star to clear the maze.
3. Went the wrong way? Drag back along your line to erase it. You can also press on any part of your line to pick it up from there.

Stars

Stars measure how directly you got there. We count every step you draw, including the ones you erase, and compare it with the shortest path. Close to the shortest path earns ★★★. Using a hint caps that maze at ★★.

Hints

Tap Hint to light up the next few correct cells from the tip of your line. If you're on a dead end, the hint shows you which way to back up. Hints have a short cooldown.

Big boards

• Touch: pinch to zoom, and drag with one finger on empty space (not on your line) to pan.
• Mouse: scroll to zoom, and drag empty space, or right-drag, to pan. Hold space and drag to pan anywhere.
• The ⤢ button fits the whole maze back on screen.

Keyboard

Arrow keys or W A S D move your line one cell at a time, picking the open hall closest to that direction on hex and circle boards. Moving back erases. H hint, R restart, M mute, +/− zoom, 0 fit, Enter next maze.

Board types

Square grids are the classic. Hex boards give six ways out of every cell. Circle mazes start in the middle and spiral out to an exit on the rim. Fog only shows the area around your line.

Print it

Tap Print to make a black-and-white sheet with a name line and an optional answer key. Choose Easy to Expert. It saves as a PDF from your browser's print dialog too.

Share a maze

Every maze comes from a seed. Share copies a link that rebuilds the exact same maze for whoever opens it.
