Hexadecimal Sudoku Puzzles

Hexadecimal Sudokus are a larger version of regular Sudoku that feature a 16 x 16 grid, and 16 hexadecimal digits. Each row, column and 4x4 block contains all the digits 0 thru F.

My Hexadecimal Sudoku puzzles are collected in 100 printable booklets per volume. Within each volume, the puzzles are also ordered by ascending difficulty. Each booklet contains eight puzzles, instructions, and answers.

Puzzles are available in hexadecimal (0-F) and decimal (1-16) notation.

Select a difficulty level:

Intermediate	These puzzles require basic Sudoku strategy. If you have not solved Sudoku puzzles before, you will probably find them quite difficult at first. Intermediate Volume 1 (0-F) Intermediate Volume 1 (1-16)
Challenging	These puzzles require more sophisticated Sudoku strategy. Challenging Volume 1 (0-F) Challenging Volume 1 (1-16)
Tough	Tough puzzles require more advanced Sudoku strategy, such as X-Wing, XY-Wing and Swordfish. Tough Volume 1 (0-F) Tough Volume 1 (1-16)
Super-Tough	These are the toughest Hexadecimal Sudokus I make, and may require a little trial-and-error to finish. Super-Tough Volume 1 (0-F) Super-Tough Volume 1 (1-16)
