Dungeon Crawl Stone Soup is a free, browser-playable, roguelike game of exploration and treasure-hunting in dungeons filled with dangerous and unfriendly monsters in a quest for the mystifyingly fabulous Orb of Zot.
Dungeon Crawl Stone Soup has diverse species and many different character backgrounds to choose from, deep tactical game-play, sophisticated magic, religion and skill systems, and a grand variety of monsters to fight and run from, making each game unique and challenging.
