Great activity that they build themselves.
My son got this for his 10th birthday. And for Xmas he got some add on’s. He loves it! And my 12-to loves it too! It all works great. We just wish the cardboard bottoms were plastic. But so far it’s great.They just make up their own tracks. The book that came with it gives great track directions as well.Added Dec 10, 2020:My son asked for more sets for his birthday and Christmas. A year later they boys and friends still play with it. It's set up in the livingroom now as he had his birthday a few days ago. He got the lifter set from my mom and he'll get more for xmas.We keep the flat cardboard pieces in the thin lifter box and all the plastic pieces in the original box. Still holding up well.

Engaging and fun, kid through adult
Best gift ever. Has entertained me, daughter in her 20s, and the recipient, an 8 year old girl, for HOURS. Easy to understand, yet to build cool stuff requires experimentation and some physics principles, all easily learnable by an 8 year old in a fun and engaging manner. I think this toy will still be played for a long time and I'm already imagining expansion packs for later gifts. Super fun. Cannot go wrong. Very fun to play with your child, as opposed to other toys which just are annoying. Important conversations can occur during the build, too, or just problem solve together. Solid five stars.

LOVE
Bought this from my daughter as a mini graduation present from her elementary school. It really was a bigger present than I realized! Absolutely love this as a dad daughter activity. They're challenging but not too hard and she's totally into it. It's definitely a starter kit so you can run out of their suggestions after a month. But I only have favorable things. It's creative, fun, great to do with your daughter or son and just overall amazing

First Impression: Almost Perfect!
I admit I have a certain fascination with marble runs, even as an adult. This one is different from anything else I've seen on the market, so naturally, I had to buy it. It arrived yesterday, and I've been experimenting with it for hours. This set is a lot of fun, and it's almost perfect, especially compared to the other marble runs I've had.The hexagonal grid is definitely unique, and takes a bit of thinking at first to get the pieces oriented properly. That's a good thing, though, right? :-) The marbles (actually steel ball bearings) stay on the track 99% of the time. The pieces don't actually lock together, and occasionally you'll accidentally bump something and knock a piece off, but it's usually easy enough to put it back. It's not really an issue for older kids and adults, but a young child whose lacks dexterity would get frustrated very quickly.I was a little surprised that the base plates are actually just cardboard ... heavy cardboard ... but cardboard nonetheless. It's only been a day, but they seem to be holding up fine so far. Other than the cardboard base plates and the steel ball bearings, everything else is plastic. From the video, I kind of thought the silver track pieces would be metal, but they're also plastic, and obviously need to be handled carefully.It comes with instructions in several languages (each language has its own pamphlet), and there are two pattern books that show different layouts, starting with simple ones all the way up to harder ones. I found them all to be super-simple, because it shows you step-by-step what to do, and where to put everything. Make sure you have your base plates turned the same way they do in the book, and use the green hexagons as guides so that you put the pieces in the proper places. Even the most complicated layout only took me about 15 or 20 minutes to do. It's worth mentioning that some of their layouts that use the cannon (included) , and I had to alter those to make them work. The cannon is surprisingly powerful, and would almost always send the ball shooting right out of the track. One ball has already rolled behind my desk and seems to have vanished from the face of the earth. They only give you 6 balls, and all 6 are needed for the more complicated cannon layouts, so that's a little frustrating. I did order all of the expansion sets and the other two "tricks" (loop and hammer), and there are supposed to be extra balls included with some of those. I wish all of the balls were colored, but it's not a huge deal. I got a red one, a blue one, a green one, and 3 silver ones.I like that the launch pad has a button that launches the balls simultaneously, making races more fun. The clear level platform pieces are sturdy and it's nice to be able to see through them. I wouldn't recommend building underneath the centers of the platforms, though, because if something needs to be repaired or changed, there's often no room to reach under and fix it. If you do build under it, stay close to the edges where you can more easily reach the tracks, otherwise you'll find yourself carefully lifting the whole platform and hoping it doesn't come apart. ;-) I wish the vortex piece was bigger so the balls would take longer to spin around it. Sometimes they just kind of drop through without any spinning action.Unlike some other marble runs, this set tends to be more horizontal than it is vertical. In other words, you're gonna need a big table. The four base plates measure a little over 24" square when assembled in a 2x2 layout.The starter set alone gives you a decent amount of pieces to play with, but you'll probably find yourself wanting the expansion kits and the add-on "tricks". The video that's in the listing is a little misleading, because you don't get the loop or the hammer with the starter set. Those are extra. They also show more than one set in the video, so go by the written list of contents rather than what you see in the video. I wish they sold individual pieces separately, because some items are only available in the starter set. I would've liked to have a spare launch pad, a spare catcher, etc, but best as I can tell, you'd have to buy a second starter set to get more of some of the items. You might consider buying two starter sets and the "tricks" add-ons, rather than a starter set, the two expansion kits, and the "tricks". The cost difference isn't much. It just depends on which pieces are most important to you. EDIT: Yes, in hindsight, I wish I'd simply ordered two starter kits rather than the expansion kits. It's about $7-8 more, but you get a lot more stuff.Value-wise, yeah, it's a bit overpriced for plastic, cardboard, and steel, but it's nicely designed, and you do get hours and hours worth of fun for the money.The set is very nicely packaged in a sturdy box (great for storage) and arrived in perfect condition.Edited to add this tip: If you have several level platforms and run out of the gray/black height tiles, use paper towel or toilet paper rolls cut to the right size instead. That'll free up a good number of height tiles, without having to buy more. :-) Usually 3 stacks of the height tiles are needed to support a level platform. I still use one stack of height tiles to make sure the platform stays in place, but I've been able to replace the remaining two stacks of height tiles with paper towel rolls. (Hope that makes sense.)

The best toy I've seen in a while!
My 7-year-old has been asking for a marble run for years now, but I've hesitated because they all look so cheaply made. Even though Gravitrax is plastic and cardboard (which made me nervous at first) it has held up really well. I love how the Gravitrax is helping my son learn through trial and error. He loves building his own tracks and making his own stunts with the marbles. (The included booklets also have excellent setups to create.) Nothing makes me happier than when he runs to the table to work on a Gravitrax build after school rather than to watch TV. My only complaint is that Ravensburger doesn't sell all of the expansions in the United States. We want to try the tunnel and elevator!*In the video, we do have a few of the extra accessories- an extra Magnetic Cannon and a Hammer. My son created this build on his own, and it took some experimenting to get it to run perfectly. He was learning and having fun!Update July 2020: Everything is still holding up very well, and they did release the tunnel and elevator in the US, so we have both of those expansions now. (Of course there are other cool expansions not yet available in the US.) I still have only positive things to say about Gravitrax!

Screen-free Fun
We purchased this for our 11 year old son for Christmas and he loves it. It's like a marble run for big kids and It comes with a book full of ways to set up the system, which I think is a great jumping off point for designing your own layouts. I didn't have to help him get started at all and he has declared it "the greatest marble run ever". If a child in your life enjoyed the plastic marble run toys in the past or is into Legos or K'nex, this would be a great option for something new. The mat pieces that you set it up on are made of cardboard, as noted by other reviewers, but it is thick and I don't think it will be a problem.

Fun for all ages...8-91!
Once we got oriented to the pieces, we all had a blast! My grandsons just wanted to start building right away, and my 91 year old father was intrigued. Amazing to find a toy that appeals to the age range of 8 to 91.I would suggest that you work through the first instructions...there aren't any words, but once you grasp the concept, it is easy to start creating. My grandsons (8 & 11) worked only the first few designs, then went crazy creating.I gave it only 4 stars for sturdiness. The silver ramps don't fasten securely onto the hexagons, so if the puzzle gets bumped, tend to slip off. Doesn't seem to bother my grandsons.I went ahead and purchased the expansion pack and was glad that I did since the boys had fun building higher puzzles.I also purchased the magnetic cannon...wow! fun!I still think this is expensive, but I know the product is well thought out.I am buying other accessories for Christmas! I can't wait to play it with my grandsons and Dad!

Great toy!
My son got this for Christmas. He is 8 years old. He is enjoying this game A LOT. His screen time has significantly decreased. He has always loved puzzles, mystery solving and reading. So this toy is good for him. His cousin who is the same age but not into puzzles and reading, he shows no interest in this game. Attached video is his 2nd day with this game; this is the last of the sample (level 3) in the booklet that came with it. Now he is proficient enough to make and explore his own setup.

A hit!
I offered this to my 9 year old granddaughter and she couldn't stop playing with it. She started out following directions, but after about 15 minutes she made her own, more complex designs. I'll get her more of this.
