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:

IntermediateThese puzzles require basic Sudoku strategy. If you have not solved Sudoku puzzles before, you will probably find them quite difficult at first.
ChallengingThese puzzles require more sophisticated Sudoku strategy.
ToughTough puzzles require more advanced Sudoku strategy, such as X-Wing, XY-Wing and Swordfish.
Super-ToughThese are the toughest Hexadecimal Sudokus I make, and may require a little trial-and-error to finish.
