Horrors of Hiroimono

Rules of Goishi

Start by picking up any stone. Continue by picking up one of the closest on any of the four cardinal directions to the most recent picked spot, and repeat until no stones are left. Consecutive picks can't be on opposite directions. If a stone is numbered with N, then it is the Nth stone picked.

 The addition of indexes makes this the GP, not the standard formulation. The automated solver won't impose the restriction.
