Weekly Puzzle: Erika’s choice

October 30, 2017

Welcome to GeniiOnline’s Weekly Puzzle, powered by Art of Play! We’ll bring you a new puzzle every Monday, then publish the solution on Tuesday. 

Erika is thinking of one of the above cards and challenges Natalie and Dave to guess which one.

Erika whispers the suit of her card to Natalie and the value of her card to Dave. After a moment Natalie says, “I don’t know which card you’re thinking of but I deduce that Dave doesn’t know either.”

Dave says, “At first I didn’t know, but now I do.”

Natalie says, “Well, now I know too.”

Which card is Erika thinking of?
