Stay Cool is easy. We ask you to do nothing complicated — but you must do it all at the same time...
When you are the active player in the first round, you must answer verbally the questions asked by your left-hand neighbor while you "write" answers to the questions asked by your right-hand neighbor, using seven letter dice to "write" three- or four-letter answers. While you're doing this, another player flips a 30-second sand timer four times, giving you two minutes to answer as many questions as possible. At the end of that time, multiply the number of answers you gave for the questions from the left and from the right to determine your score.
In the second round, you do the same thing once again with new questions, but you must tell the player watching the sand timer to flip it before it runs out of sand, with a maximum of two minutes of playing time. If you fail to tell the player to flip the timer before it runs out of sand, your turn ends immediately. However your turn ends, you score points as described above.
In the third and final round, you must do everything described in the third round except now the sand timer is hidden from your eyes!
