From the website of THE NEW YORK TIMES: the hottest, most addictive game around...now in book form!   One solid red diamond. Two solid green ovals. Three solid blue squiggles. Presto-you’ve got a set! Three of a kind--or three with nothing in common: that’s what solvers are trying to find in Set, the popular game of visual perception. Originally played with cards, it’s also fun on the page. This collection, based on a popular daily feature of The New York Times online, will be welcomed by longtime fans and newcomers alike, who can either play it solo or in a group. Just examine the group of designs carefully for number, color, shape, or shading. But remember, you have to take every element into account. With its unique mixture of visual intelligence and logic, The New York Times Set Puzzle Book will appeal to anyone from 10-100.
