Ray's Comic Series - Time Travel No.4 Future Times

This one is an absolute riot to build. Future Time is part of Ravensburger's brilliant Time Travel series, and it throws you headfirst into a gloriously chaotic vision of tomorrow: flying cars zipping between futuristic tower blocks, hover vehicles buzzing over waterways, roller coasters weaving through ultramodern architecture, and hundreds of tiny cartoon characters going about their wonderfully odd business.

Every corner of this image is packed with something new to spot. A pink convertible here, a red helicopter pod there, a waterfall tucked between gleaming white buildings: the more you look, the more you find. It's the kind of puzzle where you'll keep pointing things out to whoever's sitting nearby, whether they want to know or not.

Rated difficulty 4 by Ravensburger themselves, this is a proper challenge. The dense, busy artwork means you'll be sorting tiny cartoon figures and similarly-coloured vehicles for a good while, but that's exactly what makes finishing it so satisfying. A great pick for fans of Where's Wally-style scenes who want something genuinely tricky to get stuck into.
