Here's a way for you to carry Sudoku puzzles around with you in your Filofax.
If you enjoy solving Sudoku puzzles, you probably have a system of highlighting or crossing out candidate numbers for each square. Since this can become very messy very quickly, I have built a standards solver's tool you can use in your Filofax. Each of the 81 boxes on the grid includes candidate numbers, thus:
These are the little numbers you can cross out or circle as you're solving the puzzle, allowing you to gradually narrow down the number that belongs in that box on the grid.

It is a double-sided Personal page. As usual, you can download an editable Word file or a PDF version. Print onto A4, double-sided along the short edge. Use a craft knife to cut the sheets out using a steel ruler, using the crop marks to guide you. Then punch holes and file in your Personal-size Filofax.
Why not print a few and fill in the strarter squares from some newspaper puzzles? Then you'll always be equipped for those idle moments with your Filofax.
