Why it is different

Many puzzle books grade by clue count. Here every puzzle was solved by a program that applies human techniques in order, so the level tells you the logic you will actually need. No puzzle needs guessing: if you feel stuck, there is a move you have not spotted, and the technique guide shows what to look for. Each puzzle also has exactly one solution, checked by a second, independent solver.

How to use
