A trade paper original of brainteasers isn't Basic's usual publication; but works from the Russian traditions of math and science provide the foundation for a fine collection which invites even the most avid buff to partake. Some problems are just tricky; others are nearly impossible to solve. All are satisfyingly complex. -- Midwest Book Review
