Connect jagged blocks with stitches while matching the hole counts around the grid.
How to play
Connect every pair of blocks sharing an edge with exactly one stitch. Blocks touching only at a corner are not neighbors.
Tap a thick boundary between two cells to place a stitch. Its two endpoints are holes, and no hole may belong to more than one stitch. Tap again to remove it.
The outside clues count holes in each row and column. Bright green means the count matches; pink means there are too many.
Use Mark empty to add optional × notes. Right-click and drag to mark several cells; starting on an × erases marks. Undo reverses the whole drag.
You can also Tab to cells or boundaries and use Enter or Space. Match all clues and connect every neighboring block pair to win.
A quick example
If two neighboring blocks share three boundary edges, choose just one stitch between them. That stitch adds one hole at each endpoint.
