Ive played over 1100 times, so its not horrible, but it has some pretty glaring issues. There is no visible real world clock in-game, just the timer. The game will not connect to Game Center on its own. If you are already connected either manually, or through another game, it will acknowledge that connection, otherwise the feature is useless. The "settings" menu has one setting. You can see your stats, share the game, turn off guidance/notes or... Thats it. No color options, no way to buy the game and remove ads. Statistics are broken. You might play three times and get credited for 6 wins, or you MIGHT get a loss because you looked to see what time it is in the middle of a game. You can listen to music while playing, which should be a huge plus, but... It only works if you are NOT connected to the Internet somehow. That seems weird at first, and I didnt notice right away, but even if you mute the game volume, and youre connected, a video ad will override the mute AND your music to blast the ad at full volume. Then you have to go out and restart the music, which may or may not result in a mystery loss. So its a very basic game, but very nearly overwhelmed by its flaws.
