Sudoku puzzle consists of a grid with digits. The grid may be different sizes (6x6, 9x9, 12x12 etc.). Depending on the size the grid is divided to regions (2x3, 3x3, 3x4 etc.).

At the beginning, the puzzle provides a partially completed grid, which typically has a unique solution.

The objective is to fill a grid with digits so that each column, each row, and each of the regions contains all of the digits from 1 to the number of the grid size. The same number must not appear twice in the same row, column or in any of the regions.

I have never played this game before. I had tried the games in the newspaper, but never understood it. When I started to play this app it was easy to understand what to do. I completed all 50 levels in less than an hour. I thought that was amazing for a first time payer. So much easier than on paper.

It's really straightforward, and I like the different options/sizes and progressive levels. The stats are a little goofy. My best time was 1 second? Hmm. And now I've finished every level. Ho hum
