In each round of Ticked Off, players are shown a category, then take turns making claims of how many items they could list in that category.
Seems straightforward – but naturally there's a twist! Once all but one person has passed on increasing the target bid, a second category is revealed and each player then lists as many items as possible – but from only one of the two categories. Players then compare answers and mark out duplicates, scoring one point for each unique answer; the bidder scores two points for each unique answer, but only if he meets his bid. In addition, each player scores additional points if he listed more answers than the number bid.
