SS-tour puzzles

These puzzles are a devious variation  of the stepping-stone mazes (2011). In 2013 Bob Henderson (USA) uncovered some fascinating unique tours on small  grids. This game offers  a taster of these results. The three tutorial levels will teach you everything you need to know, while the five main puzzles ramp up very quickly to a level of difficulty that may prove surprising. Do not feel compelled to finish them! Note: you may find the puzzles easier to solver as print-and-play puzzles.
