Printable Sudoku – 4 per page
Four puzzles on one sheet: big enough for notes, small enough that one sheet lasts an afternoon. The layout most people pick.
Free to copy: schools, libraries, care homes and clubs may reproduce and hand out these sheets at no cost.
Room for pencil marks
At four per page each grid is a little over 8 cm (3.3 in) wide, with cells of about 9 mm. That leaves room to jot the possible numbers into the corners of tricky cells – exactly what hard puzzles call for.
Mixed or one level
The sheets here climb from easy to expert. The tabs above take you to each level on its own, keeping the four-per-page layout. “New puzzles” makes a fresh set whenever you like.
Answers kept apart
The answers sit on pages of their own at the end, twelve per sheet, with the given numbers in bold. Hand out the puzzle pages and keep the answers.
