Smart Toys and Games' popular range of IQ travel games have entered a number of World Duty Free stores across the UK's largest airports.
The collection of brainteaser travel games, which include IQ Fit, IQ Link, IQ Puzzler Pro, IQ Twist and IQ XOXO can now be found in the World Duty Free Stores across 16 UK airports, including London Heathrow, London Gatwick and Birmingham.
They will also be available at Eurotunnel stores as the new deal takes the Smart Toys and Games brand international.
Each game in the range contains 120 multi-level challenges that are suitable for players aged six and over. The IQ games first hit the shelves of the World Duty Free Stores in June and sales have since 'skyrocketed.'
Karen Clarke, brand director at Smart Toys and Games, said: "We have been delighted with the positive reaction we have received from partnering with World Duty Free and it's a great pleasure for Smart products to be stocked by the UK's leading travel retailer.
"Our IQ games provide endless brain-teasing fun for the whole family, so we are not surprised this series has been so popular."
Ozlem Boyaalici, UK buyer for toys and souvenirs at World Duty Free, added: "Sales of the IQ games have exceeded our expectations and we have received very positive feedback from our customers.
"We look forward to maximising further opportunities with the team at Smart Toys and Games."
