One Sudoku a day,
the same for everyone.
Everybody gets the identical puzzle each day, and the only thing that separates you is how fast you finish it. Solve it, file your time, and see where you land.
Daily
One puzzle, released at midnight in your own timezone. No difficulty setting — the daily is the daily, and everyone is solving the same grid you are.
Your time goes on a leaderboard of the day’s fastest solves, and a calendar keeps the month you have cleared.
Classic
Endless puzzles across four difficulty bands, for when one a day is not enough. Play as many as you like; nothing expires and nothing is rationed.
Classic solves are recorded separately, so practising never touches your daily run.
Hints are free
Every puzzle comes with hints included — five on a daily, ten on a Classic puzzle. They cost nothing and you do not need an account, a purchase or an ad to use them.
Coins exist for going past that allowance on Classic, and for opening a day you missed. You can earn them by watching an ad if you want to, or buy them if you would rather not. Neither is required to play.
Sudoku Hurdle Plus is a subscription that removes the ads and opens every past daily. It does not make the game easier and it does not buy you a better time.
You do not need an account
The game works from the moment you open it. Signing in is optional, and the only reason to bother is portability — it saves your coins, streak and puzzles to an account so you can carry them to another device or get them back after a reinstall.
If you do sign in, you can sign back out or delete the account from inside the app. The privacy policy sets out exactly what is kept and what is not.
