Puzzlers can have challenging fun every day of the year with 365 problemsolving exercises to test and sharpen their skills. Numbers, words, logic, concentration, creativity: they're all worked out. Puzzle icons at the top of each page explain exactly which ability is being tested and the difficulty level. Look at a diagram and figure out how many square and rectangles it would have if the diagonal lines were removed. Arrange a block of text alphabetically to find out what the 13 word would be. Complete a magic square so that it contains all the numbers from 1 to 25, and so that the sum of each line, column, and the two diagonals come to 65. These mental gymnastics will definitely keep the mind in top shape.

This product may contain chemicals known to the State of California to cause cancer,
