Octo Unleashed (Paperback)

Imagine the result if you smashed a Sudoku puzzle into a Kakuro puzzle at 150 miles per hour. That's OCTO!! OCTO is a brand new, patent pending, highly addictive puzzle that combines the positional logic of Sudoku with the mathematical logic of Kakuro and then introduces some elements not found in either puzzle to create a new standard for puzzling. The goal is to place the numbers 1 through 8 in each octagon such that the numbers are not repeated in any octagon, row, column, or diagonal. The sums of the numbers in each minor diagonal and the sums of the four numbers that border the diamonds formed where the octagons intersect are provided as clues. The numbers in diagonals have to be unique; the numbers bordering the diamonds do not. That's it-the rules are simple but the variations are infinite. Ranging from mildly challenging to brutally hard, this book introduces the Octo puzzle to the world for the first time ever!
