I absolutely love yugioh, it is one of my favorite games. I downloaded this game on steam and have had absolutley no issues with it at all. But after downloading the mobile version, my experience has been terrible. As many others have said, Connectivity issues are a huge problem. Even playing in solo mode is difficult because the game lags and crashes so much. Wish I could rate it higher but sad to say, they need to seriously rework it for mobile so that the game runs smoother.
