Sudoku - Learn and Train

Sudoku is a popular pastime. It is a number puzzle with a 9x9 playing field. You have to enter the numbers from 1 to 9 correctly, so that each number appears only 1 time in the row, column and in a 3x3 box. If you want to take a break in between or switch off from a stressful day, this is the game for you.

Little Owl's Sudoku contains 3 trainings: for beginners, advanced and experts. In a training you play level by level with increasing difficulty. The beginner training teaches you how to play Sudoku, the advanced and expert training teaches you strategies to solve even the most complicated Sudoku puzzles. Each training has an increasing difficulty level, explanations about strategies and up to 20 levels.

The free Sudoku number puzzles are generated by a sophisticated algorithm. They are unique and always solvable. Every week you will receive 1000 new and unique Sudokus. If you do manage to solve them all, you will receive a variation of a previously played Sudoku that you will surely not recognize. There are 4 balanced difficulty levels: Easy, Medium, Hard and Extreme.

The highlight of the free sudoku is the 8 different color themes. There are 2 light and plain color themes in blue and green and 1 dark color theme to play with at night. In addition, there are color themes with background images and appealing colors: Water, Clouds, Winter, Desert and Summer. More color themes will follow!

The game shows you reports about your average and best times depending on the difficulty level for the last week, the last 4 weeks and for the whole time.
The Sudoku game panel helps you keep track by highlighting identical numbers as well as rows, columns and boxes where a marked number is located. You can write notes in the boxes, just like on a piece of paper. These notes are automatically adjusted when you enter numbers. If you enter a number twice, this error will be highlighted. Of course, these features can all be turned off if you don't need them.

If you ever get stuck in a difficult level, you can close the Sudoku and start a new game at a different difficulty level and return to your difficult level later.
