Can you get the marble to the target?

This marble maze game is a single-player logic puzzle for children aged 8 to 12 and anyone older who fancies a challenge. Players stack the nine towers on the grid so that a marble dropped from the top rolls all the way to the target, working through 60 challenges that start simple and get fiendish. It sharpens planning, spatial reasoning and problem-solving while feeling like pure play, and it is just as much fun building wild runs together with friends or family. The set includes 9 towers, 3 marbles, a game grid and a target piece.

Why you'll love it
