About Puzoro

A small, independent site for daily logic puzzles in four languages.

What we make

Puzoro publishes classic logic puzzles — Sudoku, Killer Sudoku, Nonograms, Kakuro and Star Battle — in English, Korean, Japanese and Spanish. Three of them have a daily edition that changes at midnight in your own time zone; all of them have unlimited practice puzzles.

How the puzzles are made

Puzzles are generated automatically and checked before anyone sees them. A second solver, written independently of the generator, has to prove that each puzzle has exactly one solution and can be solved without guessing. The difficulty label is the hardest technique that solver needed. Daily puzzles are prepared about two months ahead and never change once they are published.

No account, no paywall

There is nothing to sign up for and nothing to buy. Your progress is stored in your own browser; if you want, switch on Continue with Google in Settings and your phone, home and work devices can share it. The site is paid for by advertising, which only appears away from the board and the controls — never right next to the puzzle you are solving.

Original games

The genres we publish are public, traditional puzzle types. Our designs, names, icons and sharing formats are our own; we are not affiliated with any other puzzle publisher.
