This is an officially branded tie-in edition with Mensa International, located in Islington, North London. Sterling Publishing, now, has an exclusive tie-in to publish children's puzzle books featuring the Mensa brand name. Renowned author Helene Hovanec - the creator of 38 kids' puzzle books - offers children a fun brain workout with some challenging juvenile trivia. Kids will love to see if they know the answers to questions such as: what summer month has no major holidays? Which Australian animals live off eucalyptus leaves? What kind of test is given to determine if someone is telling the truth? Which fictional hero travelled to Lilliput? Some quizzes are multiple choice, while others simply ask the questions, or feature fill-ins. The subjects range from art to music, sport to food, with many other categories in between.
