Hearthstone is a free-to-play online digital collectible card game developed and published by Blizzard Entertainment. Originally subtitled Heroes of Warcraft, Hearthstone builds upon the existing lore of the Warcraft series by using the same elements, characters, and relics. It was first released for Microsoft Windows and macOS in March 2014, with ports for iOS and Android releasing later that year. The game features cross-platform play, allowing players on any supported device to compete with one another, restricted only by geographical region account limits. The game is a turn-based card game between two opponents, using constructed decks of 30 cards along with a selected hero with a unique power. Players use their limited mana crystals to play abilities or summon minions to attack the opponent, with the goal of destroying the opponent's hero. Winning matches and completing quests earn in-game gold, rewards in the form of new cards, and other in-game prizes. Players can then buy packs of new cards through gold or microtransactions to customize and improve their decks. The game features several modes of play, including casual and ranked matches, drafted arena battles, and single-player adventures. New content for the game involves the addition of new card sets and gameplay, taking the form of either expansion packs or adventures that reward the player with collectible cards upon completion. In contrast to other games developed by Blizzard, Hearthstone was an experimental game developed by a smaller team based on the appreciation of collectible card games at the company. The game was designed to avoid pitfalls of other digital collectible card games by eliminating any possible plays from an opponent during a player's turn and by replicating the feel of a physical card game within the game's user interface. Many of the concepts as well as art assets were based on those previously published in the physical World of Warcraft Trading Card Game. The game has been favorably reviewed by critics and has been a success for Blizzard, earning nearly US$40 million per month as of August 2017.[2] As of November 2018, Blizzard has reported more than 100 million Hearthstone players.[3] The game has become popular as an esport, with cash prize tournaments hosted by Blizzard and other organizers. ... https://www.youtube.com/watch?v=z9HMzYDzrUE

Warcraft is a franchise of video games, novels, and other media created by Blizzard Entertainment. The series is made up of five core games: Warcraft: Orcs & Humans, Warcraft II: Tides of Darkness, Warcraft III: Reign of Chaos, World of Warcraft, and Hearthstone. The first three of these core games are in the real-time strategy genre, where opposing players command virtual armies in battle against each other or a computer-controlled enemy. The fourth and best-selling title of the franchise is a massively multiplayer online role-playing game (MMORPG), where players control their character and interact with each other in a virtual world. The most recent title is Hearthstone, a digital collectible card game. Warcraft is one of the highest-grossing video game franchises of all time, having grossed $11.2 billion in lifetime revenue, as of 2018. Expansion sets were released for Warcraft II (Beyond the Dark Portal), Warcraft III (The Frozen Throne) and multiple expansions were released for World of Warcraft (The Burning Crusade, Wrath of the Lich King, Cataclysm, Mists of Pandaria, Warlords of Draenor, Legion, Battle for Azeroth and Shadowlands).[2] At BlizzCon 2018 on November 2, 2018, Blizzard announced a remaster of Warcraft III entitled Warcraft III: Reforged featuring remodeled characters and graphics with a prospective release in 2019.[3] The game was officially released on January 28, 2020.[4] All games in the series have been set in and around the world of Azeroth, a high fantasy setting. Initially, the start of the series focused on the human nations that make up the Eastern Kingdoms, and the Orcish Horde, which arrived in Azeroth via a dark portal, beginning the great wars. The Orcs came from another world, referred to as Draenor, the world that will be shattered into pieces by demonic magics during the events of Warcraft II, thereafter being known as Outland. Later on in the series the world of Azeroth was expanded, revealing the new continents of Kalimdor, Northrend, Pandaria, Broken Isles, Kul Tiras, and Zandalar, allowing the introduction of the Night Elves, Tauren, Pandaren, and other major races into the universe. The world of Azeroth also contains the traditional fantasy setting races of elves, dwarves, gnomes, orcs, and trolls.[5][6] The series spawned several books and other media, covering a broad range of characters and timelines in the Warcraft universe.[7] A collectible card game was published, which offered those who bought booster packs a chance to gain access codes to limited in-game content in World of Warcraft.[8][9] Comics have been released alongside the books, further covering parts of the universe's storyline. A short-lived, online subscription only magazine was available but later ceased publication after five issues.[10 ... https://www.youtube.com/watch?v=MpI1yYfo_ow
