Very Hard Maths Puzzles With Answers: Sujiken Puzzles

Sujiken (from Japanese "sujikai," literally "diagonal") is a variation of Sudoku, invented by George Heineman (USA). The puzzle consists of a triangular grid of cells containing digits from 1 to 9. The objective is to fill a grid with digits so that each cell contains a digit and no digit is repeated in any column, row and diagonal in any direction. Also, no digit occurs twice in any of the three larger 3 x 3 square regions and any of the three larger triangular regions enclosed by thick borders. logic puzzle - logic puzzle books for adults - puzzle books logic - adult logic puzzle book - logic puzzle game - logic grid puzzle books - logic stacking puzzle - math puzzle books for adults - puzzle math - math puzzle games - math jigsaw puzzle - math puzzle book - math puzzle for adults - math puzzle adult
