-        There will be 9 rounds of game play. Teams will alternate rolling a die each round. The number on the dice will determine the method that both teams will complete. Your work might happen concurrently or you might have to trade-off in order to engage with each other. For example, during an Empathy Interview, one team will interview the other team, and then your switch so that the other team can interview. But, during a sketching method, both teams would be sketching at the same time.  Each number on the die has a corresponding phase of the Design Process.
