Expand your set with a smart mechanism that can hold marbles and release them at precisely the right moment. The Releaser works on three levels: marbles collect at the top, while the middle level allows you to direct the output independently in multiple directions. By choosing the direction and release order, you determine the difficulty level of the entire track.

Thanks to clever placement, the Releaser can act as a trigger for chain reactions, a timer/delay, and a starting element for other sections. Create spectacular “fireworks” of marbles and explore the principles of physics, space, and gravity in a playful way. The add-on is fully compatible with GraviTrax and GraviTrax PRO—the series combine easily.

• Strategic planning – three levels for thoughtful routes and dependencies.
• Adjustable output – directional control on the middle level in various directions.
• Variable difficulty – the more marbles pass through the trigger, the more challenging the build.
• Compatibility – works with all GraviTrax and GraviTrax PRO starter and expansion sets.
