For example, if Alice has 4 Zombies, and Bob has 3 when Zombie Boss is played, then Alice is the Zombie Boss. What happens when Bob gets another Zombie, making them tie at 4 zombies each? The card text implies that Alice would remain Boss as Bob does not yet have more than the current Zombie Boss. However, this violates the no-hidden state ideal of Fluxx, so they must either both be Zombie Boss, or there temporally be no Zombie Boss.
A: Alice remains Zombie Boss until Bob gets another Zombie or Alice loses one of hers. Yes, this does create a memory condition, but it’s easily overcome by placing the Zombie Boss rule card in front of the current Zombie Boss.
