The POOF-Slinky 0X3819 Ideal Rapid Response is a fast-paced game that pits your basic knowledge against the crazy timer. Be the first team to reach the top of the score path by quickly and correctly guessing the topics on the cards as your teammate provides clues while the marbles "click-clack" down the slide. For each correct answer, toss another marble into the top of the timer to buy more time. When the marbles run out, time is up and you move your marker up the score path. The Rapid Response Gizmo is a combination of timer and scorekeeper. The numbers that run up the middle of the score path indicate how many marbles should be dropped into the top funnel at the beginning of a team's turn.
