We were planning to workout with the free to play model for ARTHA and we've decided to make it free for all the public very soon.
The upcoming update will have the in-game store feature where players will be able to buy decks using in-game currency. We are constantly working on getting those features ready for all the players.
For those who have purchased the game can either get a refund or they will get the in-game content for the same price.
So stay tuned and we will see you very soon...:)
