From the publisher's press release: Rapid Response is the fast-paced, question and answer game that pits your basic knowledge up against a twisted timer! Families and friends will have a blast trying to multitask as the questions fly, the balls drop and the bell dings. Don’t get distracted by the “DING!” – as time quickly runs out! Quickly give your partner clues to guess the category on the card: “Cake…Ice Cream, Candles…Streamers“ Your partner shouts “Birthday Parties!” Right! Now grab a marble from the bottom trough and put it back into the funnel at the top of the slide to buy yourself more time. The object of the game is to quickly (and correctly) guess the phrases being described by your partner before all the marbles run down. Open-ended categories make it easy for all ages to get into the action – hints can be as complex or simple as you need them to be.
