Barnes & Noble Publishing, 1998 - 426 strani
Puzzlers can have challenging fun every day of the year with 365 problem-solving exercises to test and sharpen their skills. Numbers, words, logic, concentration, creativity: they're all worked out.

These mental gymnastics will definitely keep the mind in top shape.
