How Hearthstone’s team made Tomb of Terrors a fun and distinct solo mode

Hearthstone‘s newest solo adventure, Tomb of Terrors, debuts today. Hearthstone became the king of the digital card game world thanks to its multiplayer offerings, but the free-to-play Blizzard Entertainment game has found a successful format for single-player content that has players making their own decks as they fight computer-controlled bosses. One loss and you have to start over, similar to roguelikes.

This kind of solo experience started when Dungeon Run came out with the Kobolds & Catacombs expansion in December 2017. Since then, every expansion has added some kind of new spin of this mode. Now Tomb of Terrors looks to delight solo players by focusing on some of the game’s most popular characters, The League of Explorers.
