To celebrate World Environment Day, we’re offering 25 lucky readers the chance to win a Build Your Own Marble Labyrinth.

Put your maze navigation skills to the ultimate test with Build Your Own’s eco-friendly, STEM-inspired Marble Labyrinth! Two games in one and double the fun, this innovative Marble Labyrinth provides hours of entertainment.

Place your swirly glass marble at the starting point, then use the push and pull tabs to tilt the labyrinth and steer your marble to the finish. Play alone or challenge friends and family. Watch out for the traps!

You’ll need practice and a steady hand. Take your time and before long you’ll be a master!

Ready for a new challenge? Move the walls around to create your own labyrinth design. You can even rearrange the base boards to really mix things up!

Or why not try your hand at the Marble Frenzy game? Replace your labyrinth boards with the Marble Frenzy layer and you’re set to go. Place your marble in the start area, then use your awesome skills to guide each of the marbles into the scoring holes. Beware of the trap holes!

Easy to assemble using slot together techniques – there’s no glue, no mess, no fuss. Everything you need is provided in the kit – simply follow the instructions: press out the pre-cut parts, build and you’re ready to go!

Suitable for children 8 years+ and best enjoyed as a family experience.
