Sudoku 16x16 Instructions
Sudoku puzzles originated in the mid-1980s based on a number game created by 18th century Swiss mathematician Leonhard Euler, according to Sudoku Daily. Traditionally, Sudoku puzzles are built using a 9x9 grid of squares. As the game has progressed, however, larger puzzles have been created. One common size is the 16x16 grid, which uses either a combination of numbers one through nine and letters A through F or simply A through P as characters. Each row, column and 4x4 block of squares must be filled in with the available characters without using them twice in any set. For example the number one, if using numbers as characters, can only appear once in each row, once in each column and once in each 4x4 set of squares.

Find the first open box in the top row. Make sure you know whether the puzzle is using 1 through 9 and A through F or just A through P. Some boxes will be filled in already when you start so it should be obvious.

Look in the row, column and group of 16 boxes in which your box resides. Notice that groups of 16 boxes at which you need to look are divided with bold lines. Place each character once in each row, column and group of 16. Determine which characters will fit in your boxes to complete the set.
