A Hex Sudoku has a 16 x 16 grid and must be filled with numbers and letters - normally 0 to 9 and A to F, or choose the Large Hex sudoku with its 25 x 25 grid, filled with letters from the alphabet only. The rules are the same as for normal sudoku, but Hex Sudoku is more challenging.

Hex-sudoku is ons naam vir die gr��t sudoku's met 16 x 16 en 25 x 25 roosters. Die 16 x 16 moet gewoonlik voltooi word met die nommers 0 tot 9 en die letters A tot F. Die 25 x 25 Hex-Sudoku word normaalweg net met 25 letters van die alfabet gevul. Die re�ls is dieselfde as 'n gewone sudoku s'n, maar Hex-Sudoku is 'n baie groter uitdaging.
