Query: Smart, witty fun

The folks at Puzzability -- Mike Shenk, Amy Goldstein, and Robert Leighton, all "Games" magazine alums and world-class puzzle constructors -- have done an outstanding job of putting together classic "New Yorker" cartoons with an entertaining selection of different kinds of word puzzles. Sometimes you'll work from the cartoon to the puzzle, and sometimes from the puzzle to the cartoon, but you'll end each page with both a smile and a feeling of solving satisfaction. The puzzles are extremely well crafted -- hard enough to be fun and challenging, but well this side of frustrating -- and really enhance the impact of the cartoons.Strongly recommended.
