Q Ba Maze 2.0 Rails Extreme Set

Q-Ba-Maze is a unique system of colorful cubes that interlock to form a marble run.  The cubes offer different “exits” so the marbles will roll in specific directions – center exit, single exit, or double exit. 

With unlimited configurations, every build is a live demonstration of probability, physics and art, all in one!

The Rails Extreme set contains: 82 cubes in an array of fun colors, 18 rails, 4 coaster tubes, 4 marble catchers, 30 marbles, and instruction booklet.

Cubes are made from phthalate-free and BPA-free ABS plastic. 
Marbles are nickel plated steel balls. They are not magnets.

Ages: 6 to adult.
