Unstepped

Create a path by clicking and dragging from one footprint-bearing stone to the next. You cannot move in the same direction as the footprints of the stone you're on, and you also cannot backtrack or cross over your path. Release the mouse to end the path: if your path is long enough (3+ stones, or all of them if there are only one or two footprint-bearing stones), each stone your path visited will be replaced by one with footprints going a new direction than they just were.

If the path visits every footprint-bearing stone on the board, you'll be prompted to click a bordering stone to turn it over and reveal its footprints. (This is also how the game begins.) End the game victorious when every stone has been turned over to reveal its footprints, and you visit every stone in one path. Then refresh to play again!
