do credits earned on mobile transfer to the pc ?
Nitpickingly, credits aren't transferrable.
As a user, you have one account which is accessible from three sides:
- Android app,
- Ipad app,
- PC.
So, yes, you may use your credits on either platform.
Over the last 2 days I have earned 1200 credits watching videos using my smart phone and a mobile emulator. I seldom try to earn credits on the WGT PC site while I only play WGT on the PC site.
