Welcome to the Topdeck Challenge Of The Nations, an online quiz to pit Australians, New Zealanders and South Africans against each other to determine the smartest nation.

The Challenge is a series of eight quizzes starting on April 5 designed to determine once and for all who is the smartest nation.  

Each quiz you complete puts you in the running to win the weekly prize of a £100 bar tab. The person with the highest score gets the bar tab (we know you’re a brainy lot so we’ll chose the winner randomly from those who all achieve the highest score)

Keep coming back each week as not only is there a new bar tab up for grabs every week, but at the end of the eight quizzes we’ll tally up which is the smartest nation and the person with the highest score from the winning nation (chosen at random) will take home the major prize of a 14 Day Topdeck European Wonder Tour for two people!

You have to complete six of the eight quizzes to be in the running to win the major prize so if you think you know a bit about who’s who and what’s what set your weekly reminder now!
