Can I transfer my data to other platforms?

Data can be transferred between different devices/platforms if you link your Duelist ID to a KONAMI ID. For more information on how to create a KONAMI ID and link Duelist ID to that KONAMI ID, click here.

However, you will not be able to transfer paid Gems to other platforms. You can only use those Gems on the device/platform that you made the purchase one.
