Zen Sudoku

Zen Sudoku is a very nice game that will help you relax while you play a challenging game. In case you don't know the game, sudoku is a puzzle game in which you need to complete a grid with numbers from 1 to 9, but in a way that no row, column, and 3X3 areas has a repeated number.

You will be able to completely customize the games to make them more or less challenging according to your skills.

You can select the types of tiles to play with (numbers, symbols or both), the limit of hints (reveals one number on the grid), and you can also include check option (checks if the value you enter is correct), pencil marks, timer and snapshot (allows you to save the game at a certain point to start from there if you lose). As you advance in the game, you will unlock beautiful backgrounds and themes to play the games, and they will also get more and more challenging. The game has simple but nice graphics and sounds, but sadly, no music.

All in all, if you like such games and you are looking for a customizable game to pass the time, Zen Sudoku may work for you.
