Make your way through the city…
Each team gets a GPS phone with an on-screen map. The teams have to find the marked location. Once they arrive at the location, a question or commed appears on the screen. Once the team solves the puzzle or answers correctly, the team gets points and clues that lead them to the next destination. While the teams are busy solving riddles and puzzles, there is a saboteur actively trying to ruin everything. He tries to turn of the GPS devices. The teams will lose precious time and points.
