Is this meant to be an activity where the students randomly guess until they are lucky to get the answer, or are you giving out some kind of hint to the students before they guess?
How about having the possible answers on the blackboard. Take the flashcard down/given to the winning team's "point pile" as the item is correctly guessed. I'd probably have a red-herring in there so that the last slide is a 50/50 chance.
