The fundamental objective remains the same: fill the grid so that every row, column, and contains a unique set of 16 characters. Puzzles generally use one of two notation systems: Hexadecimal: Uses digits 0–9 and letters A–F . Decimal: Uses numbers 1–16 . Printable Features to Look For
Do you prefer your puzzles to use or 0 to 9 and A to F ? What difficulty level Do you need the answer keys printed on a separate sheet?
Solvers must track nearly double the number of variables across longer rows and columns.
Do not let the massive size intimidate you. Break the grid down using these reliable solving techniques. 1. Scanning and Cross-Hatching hexadoku 16x16 sudoku puzzles to print
