Colour the "globe" and respect one basic rule: neighbouring areas should have different colours. There are 100 globes and you can puzzle with each globe in 6 different ways: CLASSIC: Just keep the colours apart. SHARP: Like CLASSIC but you need to sharpen your brain TOGETHER: My name is App. Let's colour together TACTICS; A bit tricky, but you'll figure it out GREEN: The colour green is gone. Now what? RELAX: Just push 4 times, and let me do most of the work No ads, no in-app-purchases, just an honest original puzzle game. Good luck and enjoy.

We created the Printable Sudoku app in response to a survey that we administered to thousands of daily users from our Sudoku valeur.org web applications. Our survey showed that Sudoku puzzlers wanted a self-explanatory, easy-to-use app where they could print out daily Sudoku puzzles instead of going to a webpage and scavenging through multiple pages. The Printable Sudoku app is exactly what our Sudoku puzzlers want! The app gives users access to the four Sudoku puzzles we create each and every day: easy, medium, hard, and expert. Each day, you can either print each level separately, or you can choose to print all four at once. All with just a few clicks in the app! To use this app, you will need Internet access to retrieve your daily new Sudoku puzzles, as well as a printer to print them out. However, unlike other puzzle or game apps out there, the Printable Sudoku app does not have any advertising, subscription fees, in-app purchases, or tracking. In other words, you can use this app every day with no surprises or extra costs. We hope that the Printable Sudoku app will become one of your favorite daily puzzle apps.
