Burrows
The Mole has hidden its stones underground: dig a single tunnel that touches them in order and passes through every square.

How to play
- Start from stone 1 and dig a single tunnel: touch the stones in order, 1, 2, 3… and finish on the last one.
- Drag your finger or mouse from one square to the next, across or up and down. Walls cannot be crossed.
- The tunnel must pass through every square, exactly once. Every puzzle has exactly one solution.
- To go back, run over the tunnel again or tap a square you have already dug. Hint digs the right path up to the next stone, but costs points.
