From the press release: This double-sided board game offers two games in one. In Gridlock Jr. Ages 5-10, players battle a huge traffic jam, directing traffic to get the police car to the crime scene and others where they need to be. Gridlock Sr. Ages 10 and up is more challenging, with vehicle breakdowns, time pressure, and no stop signs. “The special quality of this board game is that it is cooperative. All the players must work together to free up the traffic jam; otherwise, nobody will get anywhere. Sort of like real life!”
