Field notes
The setup panel spans boards from 4×4 through 25×25 and lets players combine up to six add-on constraints; listed families include thermometers, whispers, killer cages, fog, and outside clues. The page says static rules are solved together first, then cages, lines, dots, and outside clues are derived from that solution before uniqueness carving. Saves are stored on the device, and the displayed player rating is provisional while the technique model is marked uncalibrated.
