Card Crawl Adventure is a solitaire-style card game where you build your own deck to defeat monsters, visit the treasure taverns and discover new worlds. The gameplay is simple, intuitive and fun to play. The goal is to create a powerful deck to fight monsters. You'll need to draw a path through the cards to combine them into a powerful attack. Each monster is randomly generated, and you can compete with other players on the Weekly Tavern Crawl to get unique rewards and upgrades.
