Soldoku

Sudoku meets solitare

Free · Designed for iPad. Not verified for macOS.

New in 1.1: climb the Game Center leaderboards, learn real solving techniques with 13 interactive lessons, and earn hearts from daily goals. Free and no ads. Soldoku reinvents the Sudoku you love by blending it with the thrill of a card game. Instead of just tapping numbers, you draw from a deck and play your cards onto the board — every move counts. Fill the 9×9 grid so each row, column, and 3×3 box contains the numbers 1–9, with no repeats. Simple to learn, satisfying to master. WHY YOU'LL LOVE SOLDOKU • Card-based gameplay — draw from the pile and place cards strategically. A fresh twist you won't find in ordinary Sudoku apps. • Four difficulty levels — Easy, Medium, Hard, and Extreme. From a relaxing warm-up to a real brain-bending challenge. • 50 levels — work through a journey that ramps from Easy to Extreme, earning up to three stars on each. Three stars means no mistakes and no hints. • 3 mistakes, 3 discards, 3 hints — play smart and manage your resources to win. • Note mode, undo, and erase — pencil in candidates and experiment freely. COMPETE AND KEEP COMING BACK • Game Center leaderboards — compete on fastest win and total wins for every difficulty, plus highest level reached. Filter by this week or all time. • Daily goals — three fresh goals every day, each worth a bonus heart. • Hearts — start a level with a heart, and win it back when you solve it. Hearts refill over time, and goals and achievements grant more. • Share your results — post a card of your win or your leaderboard rankings. LEARN TO SOLVE, NOT JUST TO TAP • Strategies guide — 13 interactive lessons that teach you real Sudoku technique, hands-on. • Start with the basics — Scanning, Naked Single, Hidden Single, and Note-Taking. • Then go deep — Naked and Hidden Pairs and Triples, Pointing Pairs, Box/Line Reduction, X-Wing, Y-Wing, and Swordfish. • Every lesson is played, not read — you tap through the technique on a real board. TRACK YOUR PROGRESS • Detailed statistics — games played, win rate, current and longest streaks, total time played, hints used, and your fastest solve, broken down by difficulty. • Achievements — unlock rewards like First Win, No Mistakes, Streak Master, Perfect Game, and Hintless Hero. MAKE IT YOURS • Themes — choose Light, Dark, System, or build your own Custom theme. • Custom colors — personalize the background, text, grid, numbers, notes, and highlights. • Font styles — System, Serif, Monospace, or Handwriting. • Play your way — pick "Cell First" or "Card First" input, toggle auto-removing notes, related-cell highlighting, and haptics. DESIGNED FOR EVERYONE • Guided tutorial walks you through every part of the board, step by step. • Full VoiceOver support throughout. • Beautiful, modern interface built for both iPhone and iPad. • Play offline, anytime — no internet needed for anything but the leaderboards. • Free, with no ads, no in-app purchases, and no tracking. Whether you want to unwind with an Easy puzzle, learn a technique that finally cracks Extreme, or chase the top of the leaderboard, Soldoku gives your daily number fix a brand-new edge. Draw your hand and start solving today! Developed by Connor Benedict.
