Everyday Genius: SquareLogic (2009)

Solving Tips can begin by directing attention to a useful row or column, then become more specific as you ask for further help. That makes its number-and-cage puzzles a strong choice for learning a reasoned elimination rather than accepting a filled square. The presentation is older and the arithmetic matters, but the assistance explains where the next logical step lives. Ask once, think, then decide whether you need the next nudge.
