About

Sudayku

Features
Read full description

Sudayku is your morning sudoku. Every night at midnight, four fresh puzzles appear: easy, medium, hard and expert. Everyone plays exactly the same ones, so times are actually comparable. Solve one over coffee and the rest whenever you like. DAILY LEADERBOARD Your time counts towards that day's leaderboard. Mistakes and hints add penalty time, so calm and clean often beats rushed. In the evening you hear where you finished. Past leaderboards stay around: browse back to Sudayku #1 and your own time is still there. COINS Every daily puzzle earns coins, and twice as many when you solve it without mistakes or hints. Bonus coins for all four in one day, for your streak and for winning the day. Spend them on a streak freeze, a board theme, a colour and badge for your name, or a daily puzzle you missed. Coins never buy you a better time: the leaderboard stays fair. LEARN AS YOU PLAY Stuck? The explanation hint first shows you where to look, then tells you why. And when you make a mistake, you see why straight away: the clashing digit lights up. MATCHES WITH FRIENDS Challenge a friend and play the same puzzle on a shared countdown. Not around? They play it later and you compare afterwards. YOUR PROGRESS A daily streak, badges, a chart of your solving times, and the Sudayku index: one number that follows how you're playing right now, weighted by difficulty. NO FUSS No ads, no trackers. Pick a name and play. Sign in with Apple, Google or email only if you want to play on more than one device. Add friends with a code, a QR or straight from the leaderboard.
