Magic Puzzles Sampler
by: John L. Lehet • 1
Arrange numbers into the given pattern so numbers in red squares are the sum of adjacent squares and numbers in gray squares are the difference of the numbers in adjacent squares. Simple to understand, but not so simple to do! This is a sampler of 7 puzzles that provide a great introduction to the puzzles. Another original John L. Lehet math puzzle. The deluxe version with 42 puzzles is coming soon for just $1.99.
