👆 ONE line from ① through EVERY cell — finish on the last number

Draw one line through every cell, hit the numbers in order and race the whole world — the free path puzzle that never runs out of levels.

How to play (and how to get fast)

The rules fit in one sentence: draw ONE continuous line that starts at ①, passes through every cell of the grid exactly once, hits the numbered dots in ascending order, and finishes on the last number. If any cell is left unvisited, or you touch a number out of order, the line won't complete.

Speed comes from reading the board before you draw. Corners only have two exits — decide early which one is the entrance and which the exit. Watch for cells with a single free neighbour: they must be a dead-end turn. When you see a portal pair, treat the two ends as one cell split in half. And when a lock sits between you and the next number, the key has to come first — plan the detour before your line commits.

Mistakes are free in Adventure mode: Undo rewinds one step, Reset restarts the board. In Sudden Death there is no undo — one illegal move ends the run, which is exactly why it's the leaderboard that matters most.

Frequently asked questions

Do I have to fill every cell?

Yes. The line must visit every cell of the grid exactly once — that's what makes it a puzzle rather than a maze.

Do I have to finish on the last number?

Yes. The final numbered dot is the finish line: your path must end exactly there, with every cell already covered.

What do portals do?

Portals teleport your line between two linked cells. Entering one end instantly continues your path from the other.

What are keys and locks?

A lock blocks your line until you've passed through its matching key cell earlier in the path — forcing you to plan the order of your route.
