Hearthstone is a collectable card game developed by Blizzard Entertainment, the studio behind World of Warcraft and Overwatch. Players collect powerful cards and create decks to summon minions and cast spells in order to gain control of the battlegrounds. Each card has a unique ability that can change the course of the game. The game features ten hero classes, including mages and rogues, and players can battle against each other in real-time PvP or PvE adventures. Hearthstone also includes an auto-battler game mode called Battlegrounds, where eight players compete to be the last one standing.

In addition to the classic gameplay, Hearthstone also features an all-new RPG mode called Mercenaries. Players assemble a team of iconic Warcraft characters and engage in epic combat without the need to build a deck. As players progress, they can upgrade and equip their team with abilities and treasures to fight through roguelike maps and conquer an all-new combat system. The game also includes a competitive RPG mode with roguelike elements, where players choose six mercenaries to take down their opponents and secure their bounties.

Hearthstone is set in the Warcraft universe and features beloved heroes like Illidan Stormrage and Jaina Proudmore. Players can explore iconic locations from the Warcraft universe as they master their decks and collect cards. The game is free to play and offers introductory missions to help players get started. With millions of players around the world, Hearthstone is a fun and engaging game that offers endless hours of entertainment.
