What is Sudoku? It is a Game for RALAXING and SELF-IMPROMENT
Classic Sudoku is a classic free logic game, a fun number puzzle, a kind of addictive math games, of Japanese origin and created by the best minds, that consists of filling a board of 81 squares with numbers from 1 to 9. The name of this blocks thing comes from joining the words Su (number in Japanese), doku (unique in Japanese). Hence, the correct spelling is sudoku, rather than suduku, sodoku, soduko, soduku or sedoku. Although they were created in the mid 80's, it was not until 2005 when they started to become fashionable after appearing daily in several international newspapers. Nowadays, it is very rare not to find a newspaper that contains a sudoku among its pages. To solve this math game usually takes between 10 and 30 minutes depending on the difficulty and agility of the player.

Love playing Sudoku because it's challenging. This game, in particular, is easy to use and it took no time at all to get comfortable. However, some months later after a good review, I now have a problem. Each time I want to play Sudoku I cannot get it to load. Terribly frustrating as I keep choosing this game but then get every game besides the one I want. Now when it won't load, I save my battery and go to another game.

I played one game, then got bombarded by ads that I can't escape from. Zero stars. The second time: the game appeared to be smoother with less ads. You have a choice of just taking the win or multiply ×3 if you are willing to watch ads. On occasion, when I set my phone down in the middle of a game, it makes me watch an ad before I finish a game, impacting my score negatively.

Good game. My problem is the commericals. I know that the ads pay for the free app, but c'mon! If my phone goes to sleep after the usual two minutes, I get ads, if I get a text or phone call, it goes to ads. Little greedy in my opinion. Also, give the option to keep all ads on silent! Annoying when you have your phone set up as Bluetooth for music!
