Knex sets are the perfect way to give your youngsters hours, days and weeks of fun without having to resort to the digital world. We have a good selection of Knex toys, blocks and special sets here at GAME by Sports Direct, not least immensely-popular choices like the Knex roller coaster and Knex ferris wheel, both of which would be warmly-received. We all remember the fun times we had building and red-building Knex and that popularity has stood the test of time to still be a favourite with kids today.
