Expandable Gravitrax kits expands the fun!
This game is extremely fun and truly teaches a child or an adult to understand how Gravity affects the steel ball bearings and how bridges work! It also teaches a child how to follow instructions and ultimately, their own imagination. I’m a senior and my grandson is 11. I recommend purchasing the large starter kit first, then decide on these extensions.

Great add-on but expensive for simple plastic
Great quality add-on, but feels expensive for what it is.

My son loves these sets

Watch YouTube videos for examples of how to employ the towers and other elements.
Requires extensive planning and ability to think 3 dimensionally.

Needs more parts
Does not include tower balconies or Bernoulli ramps. Not really a good way to extend your set, unless you already own lots of pro parts.
