Each round players create a deck of topics from which everyone receives one card by using multiple mini-stacks in the middle of the table.
Nobody can share the contents (or number) of their cards, but must try to identify their role through conversations.
There are no turns as everyone plays at the same time. Everyone gets to individually decide when they're done with the round, by raising their hands. As soon as more than half of the players have raised their hands, they all shout "Stop!" loudly, and the round ends.
Next, everyone must vote with their hand signals. In order to score points you must successfully identify your own role, as well as fulfill other roles specific scoring conditions.
The game continues as long as there are enough mini-stack in the middle of the table to create a new deck for the round.
