Last night, Blizzard announced on the Twitter page of its Hearthstone game that the number of users of the project exceeded the mark of 20 million people.

The new achievement of the game with certain reservations can be tied to the mobile release of the Curse of Naxxramas supplement, which was released almost two months ago. 

However, it is unclear how much of the users are on mobile devices, which is on desktop players. It is also questionable whether we are talking about registrations or active users. 

Despite the fact that the monetization of the project is not built according to the classic free-to-play canons (new content appears relatively rarely, the purchase of boosters is necessary for a successful game, as in classic desktop collectible games), the game demonstrates stable box office performance.
