Hearthstone Simulators

The HearthSim community has produced several different Hearthstone simulators in various languages, with varying amounts of gameplay implemented in each.

Fireplace

Fireplace is a Python 3 simulator and one of the original HearthSim projects. It capitalizes on the Hearthstone CardDefs XML files in order to stub most of the game’s cards and have a default implementation of all simple minions. It also features an extremely extensive test suite and was used to create the Kettle protocol, in order to play simulated games online and on the official client.

Hearthbreaker

Hearthbreaker is another simulator written in Python 3, with most cards implemented up until Blackrock Mountain. It also includes a ncurses interface. Along with Fireplace, it is another one of the original HearthSim projects.

It was used by the DeepMind team at Google for Hearthstone card generation.

Other simulators

HearthSim

The HearthSim simulator is a Java imperative simulator and, ironically, not a HearthSim project. Oyachai, its original author, has kindly allowed the HearthSim community to reuse the name, which is where it came from.
