About NumPlace

NumPlace is a free sudoku site: no ads, no account, no paywall. The name comes from Number Place, the puzzle's original American name.

Every puzzle is machine-generated and machine-verified to have exactly one solution, reachable by logical steps alone — never guessing.

Your progress is saved on your device. Only anonymous, aggregate numbers — completion times and puzzle ratings — are ever sent.

No ads. No sign-up. Free forever.
