Q-BA-MAZE 2.0 Rails Builder Set

Create unique marble runs with Q-BA-MAZE rails and cubes. Rails offer the opportunity to build multiple ramps so the marbles will zig zag every which way. Some cubes feature 2 exits, so it's a guessing game which way the marbles will go! Set includes 40 single-exit cubes, 20 bottom-exit cubes, 20 double-exit cubes, 10 straight-away rails, 4 marble catchers and 20 marbles. For ages 6 and up.
