Velvet Thread

Sew three orders of exactly the displayed path lengths. Connect matching neighbours, including diagonals. A wild knot ✦ bridges into a different colour. Collections of at least five leave a new knot at the endpoint, even when the length is only a setup rather than the current order. Choose that endpoint to prepare your next route. Any collection needs at least three stitches and uses one of twelve collections. Tap the endpoint to undo one stitch, or lift the thread to cancel freely.

Tap tiles then Sew. Arrow keys navigate; Enter selects. Retry pattern repeats the seed; New pattern varies the board and order lengths.
