Hearthstone

Hearthstone turned card battles from a slow genre for enthusiasts into fast-paced fun that anyone can grasp within a few matches, becoming the title that popularized the whole genre of digital collectible card games with a mass audience. Blizzard Entertainment built the game around the world of Warcraft, set battles in a tavern keeper's inn, and simplified the rules enough that a new player can grasp the basic moves in their very first match, while higher levels of play offer depth comparable to physical card games like Magic: The Gathering.

The game arrived on phones later than on PC and tablet, and dragging cards with a finger works well, even though smaller phone displays make reading card text somewhat harder than on the larger tablet screen the mobile version was originally optimized for. Monetization runs through card packs bought with real money or in-game gold earned by playing, a classic chance-based model similar to gacha systems, supplemented by the ability to build a deck from cards crafted by disenchanting surplus ones, and the game also distinguishes between Standard and Wild formats based on the age of the allowed card sets. Over its lifetime, Hearthstone also built its own professional esports scene and a string of expansions that gradually shifted the metagame, keeping the player base active for years after release.

Why play it: for players who want to enter card games for the first time thanks to simple rules, though full card collections and competing at a higher level require either time or repeated investment in packs.
