Karasu-OS.com is named after Karasu Operating System on DDD. It started as a website for you to record and share your cards online. But now it has many more features such as surprise guest guides, pop quiz calculators, and many other new tools! It's built by fans on a completely voluntary basis. We are not associated in any way with our official developers (great job they did making the game 👏).
How does it work?
