The next big star of puzzle games

This unique sudoku game will surely become popular, not only for its unique design of a round board, but also the introduction of differently shaded dots to put the numbers in. I spent a long time trying to convert this back to a traditional sudoku game before I gave up and realized the fact that this game is the one and first of its own. It requires a new way of solving sudoku puzzles, and it deserves more recognition so more people can try it out and challenge themselves to this wonderful new puzzle game.

A Unique Take on Sudoku

I'm a hugh Sudoku nut so I had to give this a shot when I stumbled upon it in the app store. It takes a bit to adjust to the circular boards but once you do this is a lot of fun if you're a Sudoku fan. I especially love that you can scan other puzzles you find in newspapers, magazines, etc and have them on your phone wherever you go. Can't reccomend this enough!
