This is a LEGO® Ideas set that turns building bricks into a functioning tilt maze game. It includes a 2-in-1 customizable maze system featuring a wheel-operated tilt mechanism that lets you steer a ball around obstacles and past traps. The set comes with interchangeable maze plates you can arrange to create either a classic maze or a medieval-themed version, plus a removable ball container with four orange balls and a travel lock for easy transport. A booklet with building instructions and design tips encourages you to customize your own unique maze challenges.
