Perfect Information Hearthstone is PSPACE-hard

Computational Complexity 2023-05-23 v1

Abstract

We consider the computational complexity of Hearthstone which is a popular online CCG (collectible card game). We reduce a PSPACE-complete problem, the partition game, to perfect information Hearthstone in which there is no hidden information or random elements. In the reduction, each turn in Hearthstone is used to simulate one choice in the partition game. It is proved that determining whether the player has a forced win in perfect information Hearthstone is PSPACE-hard.
