A clothesline
Sock Drawer
The clothesline steps toward the drawer. Only neighbors can trade places.
- Socks keep sliding toward the drawer. On each beat the last two hop in, and two new ones come on at the far end.
- Drag a sock sideways through its neighbor to swap them. A tap, then a tap on the sock beside it, does the same.
- Put a matching pair in those two spots before the beat. A mismatch falls off and costs a life.
Press Space, or tap the drawer, to fold early once those two match. The beats get faster. Three mismatches and the drawer jams.
