Get your imagination rolling faster and further than ever imagined. Build, bounce, adjust angles, fine-tune turns and experiment with cause and effect to see what kind of zany, zigzagging action is possible! Part art and part science, the full spectrum of colors and a complete range of stunts allow for endless construction possibilities in both form and function. The Ultimate Stunt Set features every stunt in the Q-BA-MAZE arsenal plus three exciting additions—the spiral sphere, quad-exit cubes and marble catchers. Watch in awe as marbles fly through the quad-exit cubes at random and swirl through the teal spiral sphere. Say goodbye to those wild runaway marbles, the marble catcher attachments neatly collect marbles at the bottom so you're able to quickly grab them and start the fun over again! Use your critical thinking skills to stack and interlock the translucent pieces in a way that creates an advanced marble maze that keeps everyone, including yourself, guessing!
