Update For 2010! David Dawson of Sydney has sent along his version of a MS Excel Suduko solver. Thanks to Jerry for contributing this workbook. The lower right grid shows you which of the light-yellow numbers will go to the grid. In these cases, the 3,8 square is highlighted in lighter yellow and when you click solve, an 8 will be sent to the grid. The one in yellow can only host a 3, meaning that the square with the possibility of a 3 or 8 must be an 8. There are three unfilled cells in the right column. Here is a good example in the second round. Once that information is known, new yellow squares show up in the upper right.

This means the only possibility left is a 6.Ĭlick the Solve!!! button to transfer the yellow squares to the upper left grid. Here is how it knows the lower right square has to be a 6: All of the other numbers from 1 through 9 are already used: 2, 3, 4, and 5 are in the same row. The upper right grid will light up in one of two shades of yellow to tell you the squares that can be solved. If you are new to Sudoku, this will help you to understand that solving Sudoku is a step by step process. Press Solve to put those squares in the grid. Then, new squares light up in yellow as being solvable. Click Solve to put those numbers in the grid. Jerry's workbook shows you which squares can be solved right now.

This one is cool because it lets you see how to solve Sudoko iteratively. Update Again! Jerry from Erie, New York sent in another workbook that is a Sudoku solver. Thanks to Jobey for sharing this workbook with Sudoku fans everywhere. If you have both programs, you can enter the puzzle in one form, then use Copy / Paste Special - Values to copy to the other program. This file was updated to version 2 on Aug 10, 2006.

My favorite part is this section where he shows which numbers are still possible in each cell of the grid. He reports which numbers are missing in the row, the column, and each subgrid.

The fact is that the digits from 1 through 9 add up to 45, so first Jobey figures out the total for each row, column, subgrid and compares this to 45. Instead of giving you the solution, it makes quick work of a lot of the work involved in solving Sudoku.Įnter the puzzle in his grid, and many formulas provide statistics. Update! Jobey Jones from Surrey, England sent in a workbook that is a Sudoku Assistant. So - a big thank you to Mike for contributing this workbook. Sometimes, if I could just solve one square, the rest of the puzzle would start to fall into place. It would probably be cooler if I adapted the workbook to solve the puzzle but only reveal the one square that I'm stuck on. I can now concentrate on writing the next Excel book instead of trying to solve these puzzles. It gives you the complete solution in a few seconds.

I have not protected the VBA code so anyone who is interested can poke inside to see how it works." Mike writes, "Just for fun a few days ago I decided to try and use Excel to solve Soduku puzzles. A few months ago, he sent me an Excel workbook to solve Sudoku. Trying to solve the puzzle from the morning paper quickly consumes all of the time for breakfast and can make you late for work if you are not careful.Įnter Mike Oldroyd. Thus, the possible numbers for the top left cell are 2, 3, or 7. It can not contain a 4 because a 4 appears in the upperleft 3x3 subgrid. The top left square can not contain 4 or 9 because these numbers already appear in the same row. When you consider the puzzle above, the top left square can not contain 1, 5, 6 or 8 because these numbers already appear in the first column. Each row, column, and 3x3 subgrid must contain each of the digits from 1 through 9 without any digits repeating. Your goal is to fill in the remaining numbers. In the newspaper each day, they may fill in 20-30% of the 81 numbers in the grid. Wow! Talk about a time waster! I nearly became addicted to solving these puzzles. The Akron Beacon Journal just recently started publishing a daily Sudoku puzzle in our comic strip pages.
