You are a Cahill — a member of the most powerful family in history. A dangerous enemy, the Vespers, is laying plans to destroy the Cahills . . . and take over the world. Your mission is to track Vesper suspects around the globe and foil their plots using geography, puzzles, and logic games. You can track your progress and earn medals by logging into your 39 Clues account or creating a new account. Are you ready?

Suspects: Pay attention to the hints scrolling across your screen. They’ll help you narrow down your search.

Locations: Click on each of the cities to read more information, and figure out which matches the hint most closely.

Circuit Game: Start out by focusing on the pieces along the edges. Once you have these pieces in place, you can move to the interior. Every piece will connect — there are no dead ends.

Matching Game: Begin by quickly tapping a number of the circuits. You will probably find one or two matches that way. Then, you can focus on making more strategic guesses.

Number Game: Tap or click on an empty space next to the highlighted square. Focus on finding each of the pieces one at a time. If you make a mistake, just start over — you should have plenty of time to get it right.
