ハースストーン (Hearthstone)

Hearthstone is a free-to-play digital strategy card game from Blizzard Entertainment that has attracted over 100 million players worldwide. Set in the Warcraft universe, players collect cards and build customized decks to battle against others using various hero classes, each with unique powers and special cards. The game offers multiple modes including Standard ranked play, the auto-battler Battlegrounds mode where 8 players compete, weekly Tavern Brawls with special rules, and solo PvE adventures. Players can choose from iconic Warcraft heroes like the Lich King, Illidan Stormrage, and Jaina Proudmoore across different classes such as Mage, Rogue, Paladin and more. With an easy-to-learn but hard-to-master gameplay system, players can craft decks from scratch, use pre-built ones, or copy friends' decks while collecting and crafting new cards through an in-game dust system. The game is playable across phones, tablets and PC.
