Collect as many different zombies as you can to earn points without starting a riot.
The zombies are among us, and we're gonna have to deal with them. Welcome them into your home or hunt them down in the horde. Be careful, if you make a pair of zombies in your home or in the horde, it's a riot! and you lose the round.
Thanks to the distribution of card values, take risks intelligently. Lure the zombies in or chase them out if you're likely to have pairs. When everyone has passed their turn or started a riot, it's count time!
