Last summer, my son and I were sent a set of Gravitrax toys for review and ended up loving this elaborate and creative toy. Today, we’re still playing with it regularly and have been taking a look at six of the latest GraviTrax expansions now available to make your GraviTrax system even more impressive than ever before. The instructions for the included projects are pretty clear, but for some of the more involved setups, it can be difficult to tell where to attach the balconies, since they are transparent and harder to see on the busy diagrams.

The GraviTrax PRO, along with its expansions and accessories, is a marvelous set that can build both simple setups and elaborate configurations, depending on the ages and desires of the people playing. It can be relatively affordable, just by purchasing a base set, or it can be something you literally build on over time, with expansion sets and accessories. Other than needing to be careful with your cardboard base tiles, the set is pretty sturdy and should last for a very long time, bringing joy to multiple generations. It’s already had plenty of play in my house, and I look forward to bringing it out for any design-minded visitor. This set includes 2x Sets of Instructions, 4x Card Bases, 1x Transparent levels, 6x Gravity Spheres, 3x Long Rails, 6x Medium Rails, 9x Short Rails, 1x Magnetic Cannon, 28x Curved Bases, 4x X intersection Bases, 1x Vortex Base, 2x Y Points Bases, 1x End target, 1x 3in1 Base, 4x Bases for inserts, 1x 3 Way Starter Base Insert, 2x Catcher Base Inserts, 2x Switches, 1x Base Insert, 1x Free Fall Base Insert, 20x Large Vertical Tiles, 9x Small Vertical Tiles, 8x Pillars, 4x Tunnel Pillars,2x Walls Long, 3x Walls Medium, 1x Wall Small, 16x Balconies, 4x Double Balconies. Article number: To start, a little bit of assembly is required. Hexes need to be punched out of the four base plates (tip: save these to be used as game pieces for other games you play!), and the pillars and balconies need to be assembled—this is pretty easy as everything is marked with letters and there are instructions in the booklet. Once those are set up, though, you won’t need to do it again. Ravensburger sent my ten-year-old son and me six of the latest GraviTrax expansions to try out. We rated them over four different features as follows:

As I got older, I still loved my marble game—I still have it—but longed for something more involved, interesting, and customizable. I got my kids one of those plastic marble run sets that you can put together yourself, but it wasn’t terribly satisfying for me, as it was difficult to build anything complicated. Recently, though, I had a chance to try out the GraviTrax PRO set, an improvement on the basic GraviTrax set that GeekMom Sophie reviewed for us previously. GraviTrax PRO The base tiles have some hexes marked in green, making it easier to correctly place pieces according to the included plans. The base tiles being cardboard, though, means that they could easily wear out with a lot of play, with the constant insertion/removal of pillars and tiles. They’re sturdy cardboard, but they are still cardboard. If you’re using GraviTrax on the floor, stepping on it wrong might bend or dent the base tiles, too, making them less useful.

If you’re new to GraviTrax or GraviTrax PRO, I recommend working your way through the configurations in the included booklet before going out on your own. There is one easy setup, one medium setup, and three hard setups. Working your way through these acts as a tutorial, teaching you how all the pieces work and what their capabilities and limits are. My almost-20-year-old daughter, ever the inventor, of course, improved upon some of the base projects. Don’t be afraid to experiment, even with the included projects! They are a perfect departure point for designing your own setups. My first thought about the set was that it is amazing. Building the included designs was fairly straightforward and didn’t require a lot of thinking, but building your own sets, both simple and sophisticated, really got our mental juices flowing. It was so much fun to watch the marbles go and make changes to our runs over time. Despite its enthusiasm, the Scoop is remarkably consistent and worked perfectly every time we tried it. The fact that 1/3 of the pillars don’t have a tunnel through them seems like a missed opportunity. There is no disadvantage to having a tunnel through a pillar, and having some without a tunnel limits your options.The one expansion I would advise avoiding is the Trampoline. Scoring just 18/40 in our challenge, it was inconsistent, hard to use, and included the least amount of bonus pieces which made it poor value for money. While it looks cool and is probably the most fun to watch when it actually works, it’s just not worth your money in my opinion unless you’re looking for a complete set of all the expansions. The Lifter expansion, as might be obvious from the name, lifts marbles vertically to three different levels depending on how many pieces you use to build it. It needs to be manually operated each time by a button and can send marbles in different directions at the top. What’s in the Box? I was surprised with the consistency here, simply because of how energetic this expansion is. I expected the marbles to go flying off all over the place, but they went where they were supposed to the vast majority of the time. GraviTrax CORE, PRO or POWER? Preferably all three, of course. But one thing at a time. First of all, we would like to introduce the three different GraviTrax lines here and answer the most frequently asked questions: Which GraviTrax products are suitable for beginners? What is the difference between GraviTrax PRO and POWER? From what age can you start having fun with GraviTrax? The walls have so many locations to place balconies that people who love to design and experiment with different configurations will have so much fun. Those who prefer to follow building instructions will need to be creative to make use of their options, but at least they can use the included designs to use as a starting point.
