Maybe the gameplay is okay, but the program is loaded with ads. It even needs to connect to the internet to download new ads. I would not recommend it.

As if Sudoku isn`t addicting enough, with the monthly prizes this stay-at-home mama of two not only has a way to keep her mind sharp, but also a little extra "mad" money each month. Ive won over 200.00 and counting or not. Ive noticed the game description change and it lacks any and all reference to prizes or money, both on the website and game;. PLEASE don`t nix the payout, if it weren`t for the chance to win prizes, I would just click on the the Sudoku game I paid a one time fee of 5 dollars for and have access to way more features including more levels of diffuculty, tutorials, and Sprint also offers Game Lobby for free, which allows you to upload scores and compare rank and stats with other players. As long as there are prizes, even with the ads, this game ROCKS!!

Just a great Sudoku game, free, and prizes each month (I am not ranked in the top 3 yet, good competition!) nice game

I give a 10 because it`s free and I can even win prizes (that`s what they claim, I`ll see it at the end of the month)

Anyway the puzzles are very challenging and the UI is pretyy usable for a small mobile as I have.
