Field notes
The rules hinge on two pearl types: the loop turns on a black pearl and goes straight through a white one, turning in a neighboring cell. The page pairs the playable boards with illustrated rules, strategy material, and printable worksheets with answer keys. It also presents a solver for puzzles entered from other sources; its uniqueness check is specifically described as useful to puzzle setters.
