Happy Sudoku is a sudoku app made for beginners and experienced players alike and places an emphasis on becoming a better player. It pairs a customizable board and streamlined gameplay with interactive lessons that help you improve, one technique at a time. FREE TO PLAY. NO ADS, EVER. All 16 difficulty levels, the daily streak and the core gameplay are 100% free. There are no ads, and there never will be. 16 DIFFICULTY LEVELS There are 16 different difficulties, from Very Easy to Extreme 3 - each incremental difficulty introduces new techniques required to solve the puzzle. Advancing to the next difficulty requires you to master more complex techniques such as Hidden Pairs, X-Wings and more. The app provides hands on lessons and hints to help players learn these techniques - there are 56 in total! The game comes with ~80,000 puzzles prebuilt as well as a puzzle generator so there is effectively an infinite replayability. The button placements and ergonomics of the core gameplay have been thoughtfully crafted by a veteran sudoku player who loves the game. DAILY STREAKS Finish a puzzle each day to keep your streak going. The calendar on the home screen checks off every day you play, and shows your current and longest streak. PLAY YOUR WAY • Separate number pads for digits and pencil marks • Placing a digit clears it from the pencil marks in its row, column and box • Start every game with pencil marks filled in, if you like • Tap a number to see everywhere it's placed or pencilled in • Share a puzzle with a friend by QR code or link, and race to finish the same board • Optional aids: grey out a number once all nine are placed, and block impossible pencil marks • Made for iPhone and iPad, with your progress synced through iCloud if you like • Sunny, the app's cheerful sudoku box, dresses up as you master harder levels and changes with the time of day HAPPY SUDOKU PLUS One purchase, no subscription, adds: • Hints that teach. A hint starts by showing you where to look. Ask again and it tells you what to notice, then names the technique, then walks you through the pattern step by step on your own board. Plus Check Entries, Fill in Pencil Marks, Undo Until Solvable, Solve One Cell and Show Solution. • A step-by-step lesson for each of the 56 techniques, and practice boards that need the technique you're learning • Color sets, including High Contrast, or create your own • Key layouts: swap the two number pads, use one big pad, or put the keys in two rows • Statistics: completed and solved games for every level (solved means no hints), with your best and average times NO ACCOUNTS.
