Each download holds four complete sudoku puzzles laid out two by two on a single page, with thick rules around the nine 3x3 boxes and hairlines between the squares so the grid reads clearly at arm's length. The caption above every puzzle tells you how many givens it starts with. Easy grids open with 39 numbers, medium with 31 or 32, and hard with 26 to 28, which is where a sudoku starts to need pencil marks rather than scanning.
Every puzzle is generated from a complete solution and then dug out in symmetric pairs, and the generator checks after each removal that only one solution survives. Nothing on these pages needs guesswork: there is always a next square you can place by reasoning alone. Because the same difficulty always produces the same four puzzles, you can reprint a sheet and get the identical grids, which matters if a class or a club is working through them together.
Leave the answers option on and the solutions print on a second page, each grid numbered to match. Turn it off if you are handing the puzzles to someone else and want to keep the answers to yourself. A short how-to-play note sits under the grids for anyone new to the game. The sheet is a plain vector page with nothing to type into, so print as many copies as you like.
