1. Start by building one of the configurations shown on the box.
2. Put a wooden ball in the rail car and release it down the ramp. As the car tips over, the ball is released and starts the Domino Effect. Watch the momentum wheel turn before the catapult fires another ball into the air, starting more dominoes tumbling. Momentum flows through the spinning arm and gravity release arm and into the third ball that navigates a zig-zag track before triggering the see-saw and shooting it the marble into the flag finish box.
3. Now, unleash your imagination by building new trail configurations.
