Sudoku Zero vs Sprig

Sudoku. Nothing else. Sudoku Zero is classic 9×9 Sudoku with everything else taken out. No ads, no subscriptions, no in-app purchases, no accounts, no tracking, and no popups asking for anything. FOUR LEVELS, PROPERLY GRADED Easy, Medium, Hard and Expert are graded by the techniques a puzzle actually needs, not just by how many numbers are given. Every puzzle has exactly one solution and can be solved by logic alone: no guessing. DAILY CHALLENGE A new Hard or Expert puzzle every day, the same for everyone. Keep your streak by finishing each day's puzzle on its own day, and use the calendar to go back and play any day you missed. Missed days count as completed, but they can't repair a broken streak. WORKS OFFLINE Regular games are created on your device and never need a connection. The Daily Challenge is saved once it has downloaded. HELPFUL, NOT PUSHY • Notes in their natural positions in each cell • Undo and redo • Logical hints that explain the technique, such as "Look at row 7. Only one cell can contain 4." • Optional mistake highlighting, with a mistakes counter • Highlights for related cells and matching numbers • A gentle ripple when you finish a row, column, box or all nine of a number • Automatic saving, so you can pick up exactly where you left off STATISTICS THAT MEAN SOMETHING Games started and completed, best and average times, games finished without a single mistake, and your current and longest Daily Challenge streaks. PRIVATE BY DESIGN No personal data is collected. Your games, statistics and streaks stay on your device. MADE TO BE COMFORTABLE Light and Dark Mode, Dynamic Type, and haptics and sounds you can switch off. Works on iPhone and iPad. Zero ads. Zero subscriptions. Zero interruptions.

Put one Sprig in every row, every column and every coloured region. No two Sprigs can touch, not even at a corner. Every puzzle has one solution, reached by logic alone, with no guessing. A wrong Sprig costs one of your three hearts. Every day • Today's set: five new puzzles, starting easy and getting harder, with an expert puzzle to finish on some days. • A streak that grows each day you solve a set puzzle. • The Journey: unlimited levels that get harder as you go, playable offline. Sprigs and the Garden Moss and Pebble are with you from the start. Pip, Clover and Bramble come home as you play, and Sol is a prize for the top three in a monthly live league. Cap and Ember are sold as packs, and Luma arrives with your first paid month of Sprig Club. Each Sprig brings its own colour theme for the whole app, and you can dress them from the wardrobe. Helpers Wisp highlights a square and explains the deduction behind it, Peek places one correct Sprig, and Sweep marks every square your Sprigs rule out. You start with a few, earn more in the Journey, and can buy them with coins. Leagues • Daily and monthly leagues for Today's set, and a daily league for the Journey. Groups hold up to 100 players, and empty places are filled by players marked BOT. • Private leagues for up to 20 players, joined with a code. • Scores are checked on Sprig's server, and unusual results are flagged for review. Live leagues and cloud backup need Sign in with Apple. Everything else works without an account. Settings Region letters, outlines and optional region patterns for anyone who finds the colours hard to tell apart, Reduce motion, and switches for sounds and vibration. Adverts and purchases Sprig is free to play and shows adverts between puzzles. Where the law gives you a choice about personalised adverts, you can change it any time in Settings. • Remove ads forever: a one-off purchase that stops the adverts between puzzles and after restarts. Optional adverts for extra hearts, helpers and coins stay available. • Sprig Club: a monthly or yearly subscription with no adverts at all, replays of the last 90 days of daily puzzles, two streak freezes a month, detailed solving stats, and a new collection each month that you keep. The yearly plan starts with a 7-day free trial for new subscribers. Payment is charged to your Apple Account at confirmation. Subscriptions renew automatically unless cancelled at least 24 hours before the end of the current period, and can be managed in your Apple Account settings. • Cap pack and Ember pack: one Sprig each, with its colour theme, portrait and wardrobe set.
