Selection: edgesub
Draw lines along the edges of cells to divide the grid into separate 3-handed 1-headed creatures.

Each creature is defined as a shape of 4 connected limbs. Each limb is 1 cell wide, can be of any cell length (but more than 0) and can take a turn at any point.

Each limb must have a separate end. One limb must end with a head (always clued - circle) and other 3 limbs end up with hands (whenever clued, their directions matter - arrows).

Cells within a single creature can never form a loop - in other words, the creature must never contain a 2x2 region or touch itself.
