On your turn, choose your best category and call out the number (e.g. category is Height, and value is 5 feet) The other players then read out the value in the same category from their top card. The one with the best or highest value wins, and that player collects all the top cards, including their own, and moves them to the bottom of their pile. It is then their turn again to choose a category from the next card. The person with all the cards at the end is the winner.
