Is Gods Unchained free?

Excuse me, could you please clarify if the game Gods Unchained is available for free? I've heard a lot about its unique blockchain-based features and am interested in trying it out, but I'm unsure if there's a cost associated with accessing the game. If there is a fee, could you also elaborate on the pricing structure and whether there are any in-game purchases that players might need to make? Thank you for your time.
