A cozy path puzzle
with a yarn-loving kitten.

Start on 1 and unroll a single line of yarn through the numbers in order, filling every square of the board exactly once. Knitting needles block your way and every puzzle has one answer โ€” drag back to undo, and work it out move by move while the kitten keeps you company.
