Ten people, and three of them are lying
You sit down with nine strangers, and three of them are quietly working against you. Those three were shown each other in the dark before anybody spoke, so they know you are not one of them, while from your seat all nine look the same. Players call those three black and everybody else red, after the colour of the cards dealt.
But they know less than you would think. Each of the three knows two partners and nothing beyond them, so the other seven are as much of a puzzle to them as they are to you. And because they have to stay hidden, they talk, accuse and vote exactly as everybody else does.
What’s next: two more free ideas — who is actually at the table, and how each side wins — then a quiz that marks itself.
