Field notes
The difficulty scale rates each puzzle from 1 to 1,000 according to the difficulty of its logical steps. The lesson library pairs eight basics lessons with 56 technique lessons, including X-Wing and Swordfish, and says examples come from the same solver used to rate puzzles. Hints expose candidate evidence and the deduction before changing the board, leaving the player a chance to make the move.
