As with all the sudoku puzzles on this blog (unless stated otherwise), I created it using a C program, which I wrote in 2012.
Usual sudoku rules apply: Fill in the empty boxes so that each row, column and 3x3 mini-grid contains each of the numbers from 1 to 9 exactly once.
You can print it out and solve it on paper or you can click the Solve online link below the puzzle to work it out in your browser.
If you enjoy it, please share it on your favourite social media platform. There are buttons below the puzzle to help you do this.
This puzzle was also published in the newsletter of the IT department where I work as you can see below:
