The only requirement is that players log in to both platforms with a GOG account, which may be acquired for free. Gwent players who have been playing the game on the PC will be able to carry over their progress and purchases, including their entire card collection, to the iOS version. The game is still free-to-play, but according to CD Projekt Red, the pre-orders will help make sure that it will be ready to launch by October 29. Gwent is now available for pre-order on Apple’s App Store.
