Free printable hard sudoku puzzles for experienced solvers who prefer working on paper. Hard puzzles require intermediate techniques — pointing pairs, naked pairs, and careful candidate tracking. Solving on paper gives you the freedom to write small candidate numbers in each cell and cross them out as you eliminate possibilities. Completely free, no account needed.
