The Croupier tool was created by Agile Stationery to enable remote teams play cybersecurity card games like the Elevation of Privilege and OWASP Cornucopia on video calls using physical cards.
In person, it's really easy to shuffle and deal out cards so that each player has a random hand of cards to play. The random element is important, but is harder remotely, and so we produced an online tool, Croupier, to take care of the shuffling and card-dealing. The tool generates random hands for remote workers who each receive the deck and fetch their hands ahead of joining the session.
