Teams stranded on an island must pass through 9 zones to passing ship to be rescued.
Teams are stranded on an island. To escape they must spot a passing ship and send it a signal. While they wait, they need to adapt to island life to survive.
The island, represented on a tablet, is divided into nine zones. In each zone, they are faced with a series of challenges focusing on different aspects of island survival including water, weather, first aid, building shelters, signalling, and the like. Items washed up on the shore will help them in answering the challenges. Completing the challenges successfully will give them vital survival skills.
Teams need to gain enough knowledge of each aspect in order to survive. Too much time in a zone and they will lose time to gain knowledge of other survival techniques. Too little time and they will not gain the vital knowledge they require. Once they leave a zone they cannot return.
Teams eventually determine the name of the ship, and when it will be passing. Successful teams signal the ship and are rescued. The team with the most points is declared the winner.
