The game is great, I love the idea of a points system along with a leader board. I also love the guild/club system since you can talk to others that enjoy the game too. It is great, I mean after all it is this app so it has to be great, but the additions make it that much better. The only issue I have with the game is that I continuously lose my points and not like the regular month change type of deal but every time that I close Sudoku for more that a few minutes and then I open it up again, all my points are gone. On the first day I had racked up more than 600 point, and I know it’s not a lot of points, but I lost them the next time I logged on. It also didn’t just happen that one time, it happens every time I leave Sudoku . I feel so bad for leaving a 1 star since that app is so great, but I feel like I am getting cheated out of this great feature, and I hope to receive some support on how to resolve it. As soon as it is resolved then I will withdraw my review and replace it with my real review of 5 stars.
