What is in this pack

If you have ever squinted at a Sudoku in a newspaper or on a small phone screen, you already know why large print matters. This pack gives you five original puzzles with one spacious grid on each page, set in a clear typeface so the numbers stay easy to read. Print it at home on ordinary US Letter paper, then solve with a pencil at the table.

The first three puzzles are Easy. Every empty square can be found by scanning a row, a column, or a 3 by 3 box. The last two are Medium. They still have exactly one solution, and you can still finish them with logic alone, but you may also need to look for pairs of numbers. A short how-to sits at the front of the PDF. Full solutions are on the last page, so you can check your work when you are ready.

How to print so the numbers stay large

Open the PDF and print it on US Letter paper (8.5 by 11 inches). In the printer dialog, choose 100 percent, or Actual size. If you choose Fit to page, the grid will shrink and the type will be harder to see. Black ink on plain white paper is all you need. You may print extra copies for family, a classroom, or an activity program. Please do not sell the file.

How to play, and a few tips

Fill the 9 by 9 grid so that every row, every column, and every 3 by 3 box contains the digits 1 through 9 exactly once. The dark numbers are given at the start and should not be changed. You never need to do any math, and you never need to guess.

Start with a row, column, or box that already has many clues. Look for a cell that has only one possible digit, or a digit that has only one possible place. Write lightly in pencil so you can erase. A simple habit that helps is to pick one number, such as 5, and scan each box for the one square where it can go. When a row, column, or box is almost full, the last numbers are often obvious. If you get stuck, take a short break and look again.

Each puzzle in this pack is generated by a computer program and then checked by a second program. We confirm that the puzzle has exactly one solution and that it can be solved by logic alone. Difficulty is set by the techniques the puzzle needs, not by hiding clues at random.
