From the box:
The adventure game based on the best-selling book!
You've been shipwrecked on a deserted island on a deserted island with nothing but your wits and some string to save you. Thank goodness you've been reading your Dangerous Book for Boys! Use your skills to complete solo or group challenges, test your knowledge of facts from the book, or put your mental agility to the test. Each success wins you a puzzle piece so you can "build" a raft and sail off the island. The first adventurer to travel along the whole track and complete their raft can sail away into the sunset in victory!
Girls are invited to play this game too, but they must agree to be honorary boys for the duration of the game by saying: "Boys are fantastic, girls are elastic!" three times.
