Draw one continuous line that passes through every cell of the 6×6 grid exactly once, reaching the numbered cells in order — 1, then 2, all the way to 8.
- Start on the cell marked 1. Tap a cell directly above, below, left or right of the line’s end to extend it.
- The line may only move between touching cells — never diagonally — and may never cross or reuse a cell.
- Tap the end of the line again to undo a step, or tap any earlier cell to retreat to it. Clear resets back to the 1.
- You win when the line fills all 36 cells and the numbers are hit in ascending order. The live read-out tracks cells filled, time and whether the order still holds.
- Stuck? Hint extends the line one correct step; Show solution reveals the whole route.
