Every puzzle has one answer and needs no guessing." url: https://sudokuflow.com/printables/sudoku-16x16/ language: en --- [Printable Sudoku puzzles](https://sudokuflow.com/printables/) # Printable 16×16 Sudoku A 16×16 Sudoku has sixteen rows, sixteen columns and sixteen 4×4 boxes. Instead of 1 to 9 it uses sixteen symbols: the numbers 1 to 9 and the letters A to G, so every square still holds a single character. Print one sheet or ten at once; each puzzle's answer comes on the page after it. ## Quick answer Every puzzle here has exactly one answer and can be solved without guessing. Easy puzzles need only naked singles: a square where just one symbol is left. Medium puzzles also need hidden singles: a symbol that has only one place left in a row, column or box. ## All 16×16 sheets 200 sheets, one puzzle each: Easy from sheet 1, Medium from sheet 101. **Easy**: Every step is a square where only one symbol is left. ### 1

## Tips for a 16×16 grid - Start with the rows, columns and boxes that already hold the most symbols: they have the fewest gaps to check. - Write small notes in the squares. With sixteen symbols, notes save a lot of rescanning. - Work one symbol at a time: find every place the 1 can still go, then the 2, and on to G. ## More to print [Printable Sudoku →](https://sudokuflow.com/printables/sudoku/) [Samurai Sudoku →](https://sudokuflow.com/printables/samurai-sudoku/) [Jigsaw Sudoku →](https://sudokuflow.com/printables/jigsaw-sudoku/) [Large print →](https://sudokuflow.com/printables/sudoku/large-print/) [Sudoku for kids →](https://sudokuflow.com/printables/kids/) ![Sudoku app icon](https://sudokuflow.com/assets/app-icon.png) ## Want more boards like this?
