Tap a yarn ball in the pile. It hops into a cushion and kittens of that colour start pulling stitches.
Knitting unravels from the top. A stitch is loose only when the stitch above it is gone. Look for the little white thread on loose stitches.
The number is how many stitches the ball still needs. When it hits zero the cushion frees up.
A ball with nothing loose to pull just sits there. Fill every cushion with sleeping kittens and the level is lost.
Tangled balls are two-tone: they unravel the first colour, then turn into the second.
Deeper balls unlock once the balls resting on them are gone.
Boosters: +Cushion adds a cushion, Hook pulls a ball back out of its cushion, Snip splits a tangled ball's second colour back into the pile. Win without boosters for three stars.
