SabberStone 2.1

Massive changes and updates are applied! Please check the Changelog:


State of Implementation: 98% (Rise of Shadows 94%, Rastakhan's Rumble 95%, The Boomsday Project 98%, The Witchwood 99%) of current Standard Cards (Year of the Dragon)! (23.07.2019)

SabberStone is just another Hearthstone simulator and implementation, written in C#. The project was started in Nov'16 while trying to implement aura, buffs & triggers into Brimstone. Focused to prototype my so called onion system I created SabberStone, which is using a layer approach to handle entity changing enchantments. Since then I haven't stopped implementing day by day new cards, new tests and new stuff. I created for fun a visualisation and a scoring based tree search a.i. which can be used to play games (SabberStoneGui).

By now this is a one man show, but there is still a lot of work to do, so any help is appreciated. The base code of Brimstone was a great inspiration for this project. Big thanks to @Pattux, @Patashu for helping on hearthstone super science problems ^^ thx @Katy for inspiration. And thx a lot to @Citiral, @BertP for working out on the stove implementation. And thx to @Milva who did a refactoring on the aura & enchantment system, with great value and is working hard for this project! You're welcome!

    Core simulator engine, all the functions needed for the simulator are in here. Check out the Wiki Link for informations about the core and how to use it.

  • SabberStoneCoreTest (.NET Core)

    UnitTest for the simulator, there is a generated test for each card in the current game.

  • SabberStoneCoreConsole (.NET Core)

    A test project to run simple codeline based games to test outcome.

  • SabberStoneBasicAI (.NET Core)

    A test project to run A.I. simulations with predefinied decks and strategys.

  • (deprectated)SabberStoneGui (.NET Framework) (This is currently reworked in a Unity3D GUI Client with a GameServer)

    A test project that shows off a visual implementation of the SimpleAi project. This is probably where beginners should start looking at. There is a simple GUI which allows different decks to play against each other with different strategys. Check out the Wiki Link for informations about the use of SimpleUi.
