Read starter guide by scorpion first if u haven't. This thread used mainly to address some issue that's not mentioned yet in the first thread. 1. Bind Your Account (VERY IMPORTANT!) This is the most important thing to do if u don't want to lose your game progress. I see many players reinstall the game only to find that they lose their game data. Your account are not saved automatically in google play, u have to create konami id and set up your account for data transfer. Go to setting (in the top right in home screen) > Data Transfer Settings > Launch Browser for Data Transfer Set Up. You will be redirected to a konami site, register konami id, and done, your game progression will be safe now. 2. Learning Yu-Gi-Oh General Rules (for newcomers) It is necessary to understand yu-gi-oh game mechanics to fully enjoy the game. For those interested about the game rules, you can read the general rules here (skip the part about pendulum, syncro, and xyz monsters as they are not in the game).
