Printable Sudoku

Eight puzzles on one sheet — two easy, two medium and four hard — with the answer key on the last page. The set is regenerated every day, so printing it tomorrow gives you eight new grids.

How to print without wasting ink

The grids are plain black lines on white, so there is no background to burn through a cartridge. If your browser adds page headers and footers, turn them off in the print dialog — the puzzles are laid out to fit the page without them.

Which levels are on the sheet

Easy and medium grids are solved with single candidates alone, which makes them comfortable on paper, where erasing pencil marks is awkward. The hard grids each need at least one elimination — a naked pair, a pointing pair or a box/line reduction — so leave room in the margin for candidate notes.

The same puzzle generator feeds the online game, where notes, undo and step-by-step hints are built in: easy, medium, hard, expert, master and extreme. There is also a daily puzzle archive.
