There’s movement and surprises at every stage of this fun, robot-themed domino set. Set the dominoes in motion and watch as they release a ball and unleash the mighty robot hammer. Start by building one of the configurations shown on the box. Watch the Domino Effect as your dominoes topple and release a wooden ball into the transparent tunnel. The ball unleashes the hammer which pushes over more dominoes and launches the momentum wheel. A finishing flag pops up for a dramatic ending as your last domino falls. Unleash your imagination by building new configurations.
