How to Solve a 16x16 Medium Level Sudoku?

On this page, you can play a huge Sudoku of medium difficulty level. The game board is 16 by 16 cells. Each cell must be filled with a digit from 1 to 16 so that the values do not repeat in rows, columns, and 4 by 4 squares. The game is considered finished when all cells are filled with digits.

Here are a few tips on how to solve a large Sudoku faster:

• "Scan" all numbers in order; your goal is to fill all possible cells with the number 1, then 2, and so on up to 16.
• Don't try to fill in all the numbers in a row, column, or 4 by 4 square at the very beginning of the game. You'll waste a lot of time, and it's not very effective.
• If you get stuck in one area of the game board, leave it and move on. Often, your eyes get tired of looking at one point and don't see obvious solutions; you need to change focus.
• Use the technique of the last possible cell. This technique will help you solve most of the digits in the puzzle.
• In the final stages, the strategy of the last empty cell can be very helpful. It is very useful when there is only one unfilled cell left in a row, column, or additional block.
