Thunderstone is a fantasy deck-building card game designed by Mike Elliott and published by Alderac Entertainment Group in 2009, with artwork by Jason Engle. Each card has dimensions of 6.3cm x 8.8cm. Each set comes with a stone artifact. It has been translated into several languages.
Gameplay involves building a deck of adventurers and equipment to defeat monsters. Each turn players must decide whether to visit the "village" to purchase cards, upgrade heroes and other actions or if they will face a monster in the current dungeon using the heroes and equipment in their hand. Defeated monsters are added to a players deck as well, where they may contribute money and/or other bonuses when in hand.
