Sudoku that actually lasts. Samurai Sudoku and 16×16 "Super" Sudoku for when you want a puzzle that takes more than a few minutes — and classic 9×9 Sudoku for when you just want a quick one. These are proper puzzles. The Samurai and Super Sudokus come in four levels of difficulty and none of them are trivial. If you complete one, you will have genuinely solved it. There are no cheats and no hints to carry you past a square you're stuck on. The 9×9 Sudokus come in the same four levels, from a gentle warm-up to genuinely fiendish. THREE WAYS TO PLAY • 9×9 — the classic, quick and satisfying • Samurai — five overlapping 9×9 grids for a much longer solve • 16×16 "Super" — a giant grid using numbers and letters (0–F) HELP WITH THE LEGWORK, NOT THE THINKING The app takes care of the bookkeeping so you can concentrate on the puzzle: • Auto pencil marks that fill in and update every possible number for each square • Highlight every square a chosen number could go in, so patterns jump out But nothing here shortcuts the mental process — the solving is still all yours. A NEW CHALLENGE EVERY DAY • A fresh daily puzzle for each of the three styles, every single day • Build and protect completion streaks, and earn streak freezes as you go • Over 1,800 puzzles across dozens of packs, plus the daily challenges BUILT FOR HOW YOU PLAY • Everything auto-saves, so keep several puzzles on the go at once • Play completely offline — no connection needed • Light and dark themes • Made for pen-and-paper traditionalists too: share an image of any puzzle to print and solve the hard way, with no on-screen assistance BIG PUZZLES, ANY SCREEN Because these grids are large, the app is at its best on a tablet or a large-screen phone. But every grid pinch-zooms, so with a little patience you can play on almost any device. An optional ad-free purchase removes ads entirely.

About

Flying Penguin

Features
Read full description

Learn maths while flying through a fast and playful arctic adventure. You are a flying penguin, and every second a new set of five rings appears ahead of you. Your challenge is to solve the question and fly through the ring with the correct answer. But stay sharp: the correct answer is not always there. Sometimes the smartest move is to dive into the water and swim underneath all the rings. LEARN WHILE YOU PLAY Choose what you want to practise: • addition • subtraction • multiplication • division • percentages • mixed questions Pick the type of questions you want to practise and choose a level that matches your ability. FIND THE RIGHT WAY THROUGH Each new question gives you five rings to choose from. If one of them shows the correct answer, fly through it. If the correct answer is missing, dive into the water and pass safely underneath. A wrong choice costs you a life, so look carefully before you make your move. KNOW THE ANSWER? GO FASTER Already know the answer? Tap the correct ring as soon as you spot it and your penguin will speed towards it, flying through at twice the normal speed. React quickly and you will also earn double points for that answer. It adds an extra challenge for players who want to combine accurate maths with quick thinking. CHOOSE YOUR OWN LEVEL Practise at a difficulty that suits you. Start with easier calculations and gradually move on to more challenging levels as your maths skills improve. You decide what to practise and how difficult you want the questions to be. UNLOCK NEW CHARACTERS Collect points while you play and use them to unlock new penguin characters. Keep improving your score, discover new characters, and build your collection as you progress. FOR DIFFERENT AGES AND ABILITIES • Ages 5–8: practise addition and subtraction • Ages 9–11: improve times tables and multiplication • Ages 12+: work on division, percentages, and mixed questions Whether you are learning the basics or looking for a faster challenge, Flying Penguin turns maths practice into an active game. FLY, DIVE, AND IMPROVE Solve the question, choose the right ring, dive when there is no correct answer, and react quickly to earn double points. Keep flying, keep practising, unlock new characters, and become faster and more confident at maths.
