The chunky magnetic blocks click together into straights, curves, bridges and overpasses. Set the little train on the track and it holds on with magnets, so it keeps going up the climbs, over the top and right along the underside of the raised sections. Kids build it, flip it and rebuild it into something new every day.



1Click the magnetic blocks together into a loop.
2Add bridges and raised sections on support columns.
3Switch on the train and watch it run over and under the track.
Working out how to join every loop.
Planning heights, bridges and crossings.
Every layout is their own design.
The upside-down run never gets old.

Got the big set and it takes over our entire living room. Don't care. Seeing my kids collaborate and problem solve is worth the mess.
My husband and son have a track building competition every Sunday morning. It's become their whole thing. I love watching them.
We've had this since September and it still gets daily use. That NEVER happens with toys in this house.
The magnets make a satisfying click when they connect, and my daughter enjoys putting the tracks together. She's made so many different layouts and is proud of every one.
She seemed to enjoy it. The magnets are surprisingly strong. Taking off one star because the instructions could be clearer. Nice gift for my niece.
My kids enjoy the building process. Pieces are well made. I'd give 5 stars if the set had more variety in track shapes. Works as advertised.
The magnets are strong, the pieces feel smooth and the car works reliably. It doesn't feel flimsy at all.
Built tracks all day. Zero complaints about being stuck inside. Snow day hero.
My child used the track set for a school science project on gravity and angles and got an A+. We had a lot of fun building it together.
We like it. Not the BEST toy ever but definitely solid. My boys age 4 and 7 both have fun with it which is a plus. Pieces feel premium.
Gift for my nephew. Now I need one for my own children because they will NOT stop talking about it.
Magnets hold well. Children are happy. Not revolutionary but a reliably enjoyable toy that gets regular use in our house. Good quality.
My kids opened this first and haven't stopped playing with it. The excitement on their faces was priceless. Best Christmas present!
The track set has become the favourite building toy in our house. I'm also grateful there aren't tiny bricks all over the floor anymore.
Magnets are strong and my girl likes building with it. Only reason it's not 5 stars is the car could be faster. Pretty good toy.
This is a well-made set. My daughter uses it often and likes testing out different track layouts.
Got the Master set for Christmas and my kids haven't stopped playing with it. They work together to build massive 3D structures. It's teaching them teamwork without them even realizing it.
The tracks are decent but the car derails constantly on anything steep. My kids got frustrated and stopped using it after a few days. Honestly expected more for the price.
This was a great Christmas gift. The kids have been building together without arguing, and all the pieces have held up well.
Bought this for the holidays and it was the only gift that kept ALL ages entertained. From my 3 year old to my 10 year old.
My kids picked this up for Christmas and it's been their favorite gift. They've been building together peacefully which is rare. Would definitely recommend.
My boy asked for MORE track pieces for christmas instead of video games. i nearly cried
We got the larger set and it has been worth the money. The kids build huge structures that sometimes stay up for days. The pieces feel sturdy.
My kids enjoy building together and the build quality is good. The pieces have survived daily play well. Nice toy set.
I'm an engineer, so I enjoy seeing the track designs my seven-year-old comes up with. It's a fun way for him to experiment with balance and shapes.
Bought this as an early Christmas gift and my kids have been playing with it nonstop. The magnetic system is genius and makes cleanup easy too.
My seven-year-old keeps making bigger and more ambitious tracks. Yesterday he built one across three rooms. I love seeing what he comes up with.
My 4-year-old has grown so confident with this toy. He builds independently and beams with pride at every success.
Bought it on impulse and don't regret it. My boy's been building tracks after school most days. Solid build quality. Just wish cleanup wasn't such a production.
My girl has autism and this toy has been ideal for her. The predictable magnetic connections give her confidence and she plays independently.
We bought one set, then a second, and now we're thinking about another expansion. Clearly it's been a hit here.
Track blueprints. In a notebook. Before building. She's 6. This toy turned her into a tiny engineer and Iβm HERE for it.
My preschooler's teacher noticed improvement and asked what changed. It turned out to be this toy. Fine motor skills BOOST.
My son likes building with this and the pieces have stood up to daily use. It's a decent set for the price.
This has completely replaced screen time after school. No fights no negotiations. They dump out the pieces and start building. Miracle toy.
We started with a smaller set and ended up getting the bigger one. The kids keep thinking of new ways to use the extra pieces.
We bought this for our five-year-old. He likes it, and the pieces click together easily. I just wish it came with a storage bag.
The kids stayed busy building tracks while I cooked Thanksgiving dinner. I was grateful for that bit of peace in the kitchen.
Every day it's a different design. My kid surprises me constantly. The creativity that comes out of this toy amazes me.
I bought this skeptically but my kids proved me wrong. They have fun with it more than any other toy. The magnetic system is brilliant.
My 4 year old builds on her own. Her face when the car makes it through the whole track is PRICELESS. Pure joy every single time.
Focusing is hard for our son. But this? He'll sit and build tracks for 45 minutes straight. His therapist even recommended we keep using it. ADHD household here.
My 7-year-old enjoys the building process. The train runs smoothly and the tracks stay connected well. Well-made pieces.
Just get it. Stop reading reviews and buy it. Your children will thank you.
The build quality is average. My son liked the tracks at first but lost interest fairly quickly. It might suit younger kids better.
The Pro set is ideal for one kid. My boy has endless possibilities and hasn't complained about being bored once since we picked it up.
Yooo this thing is legit. my 7yr old hasn't touched his ipad in weeks. WEEKS. if you're on the fence buy it
I thought this would be another toy collecting dust, but my wife was right. I've even caught myself building tracks after the kids have gone to bed.
My 6-year-old struggles with focus but this toy keeps him engaged for 45 minutes at a time. Watching him problem-solve when the car doesn't make it through is incredible.
Two months in. Still the first thing they reach for. Starting to think this is the greatest toy ever made.
My boy creates museum-worthy structures that we leave up for weeks. The Master set is incredible for kids who love building.
My girl has built over 50 different track designs in the past month. The versatility of this toy is outstanding.
The magnets have a nice snap to them and the pieces seem durable. I would like a few more curved sections in the set.
My kids collaborate on massive track builds instead of fighting over tablets. Miracle toy! This toy has brought siblings together.
The magnetic connection is so satisfying even I can't stop clicking pieces together. Excellent sensory experience for children and apparently for adults too.
Grandma here. Bought this for my granddaughter's birthday and now every grandchild wants one. I've bought 4 so far. Worth every penny.
He literally wakes up and goes straight to it before breakfast. The magnets click together so easily that he doesn't need help at all. I'm ordering the expansion pack today. Ok so I bought this on a whim and it's now my kid's favorite thing in the entire house.
My girl enjoys building and the pieces are durable enough to survive her rough handling. Good toy for creative play.
From a dad who's assembled a million toys: this one delivers on its promise. Simple to use and endlessly entertaining.
We've had this for two months and it still gets daily use. The pieces are holding up perfectly and my kids' builds get more impressive each week.
When he opened it, my six-year-old said it was the best day of his life. Hard to beat that reaction.
I bought this as a rainy day backup activity and now it's the MAIN activity. Every single day.
My boy has learned about gravity and momentum by experimenting with different track designs. Worth the price. Good educational toy.
We're on month 3 and zero signs of slowing down. This toy has legs. 100% recommend.
Peaceful Saturday mornings now. Children build tracks. I drink coffee. Everyone's happy. 5 stars forever.
Car does the job nicely on most tracks. Sometimes it stalls on steep parts but my girl redesigns around it. Good problem solving practice I guess. Decent building toy.
Bought it for my friend's kid's bday and now the parents keep texting me asking where I picked it up. A+ gift.
My girl has learned a lot about problem solving through trial and error with different track designs. Good educational toy.
I'm happy with the set, but I'd like a few more pieces for the price. Good overall, just not quite five stars for me.
My daughter is five and told me she wants to be an engineer after building with this. That was lovely to hear.
It's a hit with my 6 year old. She builds something new daily. Sturdy pieces. Only knock is we ran out of straight pieces too quickly.
The way my kids cheer when the car completes a track they built together... that's worth any price tag.
My daughter likes trying different ideas until she gets the track working. It's been a fun way for her to learn by trial and error.
Show and tell was a HIT. Apparently the whole class went nuts over the track he brought in. Teacher emailed me asking what it was lol
My 6-year-old son has become so patient since getting this toy. He works through problems calmly when his tracks don't work initially.
Bought during the fall sale and it's been the best purchase I've made all year. My kids are genuinely happier.
My child played with it for about a week before moving on to something else. It's fine, but it didn't hold their attention as long as we'd hoped.
Good toy for multiple children. My three kids aged 4, 6, and 8 all enjoy playing with it together.
Magnets snap together nicely. My kid likes it. The car battery dies fairly quickly but overall no major complaints. Good toy for the price point.
Better than expected. Way better. My kids collaborate and communicate and celebrate together. It's beautiful to watch.
My kids are creative and engaged and cooperative when they have fun with this. That combo is unheard of. I don't usually write reviews but this toy earned it.
I bought the Pro set and it was worth every penny. My girl sits quietly for almost an hour building elaborate tracks. The train makes it through her crazy designs which keeps her motivated.
Visiting family saw the kids playing with this and ordered 2 sets on their phone before they even left our house. Sells itself.
Not gonna lie I have fun with this after the kids go to bed. Building tracks is weirdly meditative.
It's a solidly made track set. My daughter enjoys connecting the pieces, and the vehicle runs smoothly on the tracks she builds.
We're talking 1-2 hours of focused independent play. That's unreal for my kids. Can't believe how long this holds their attention.
My girl's creativity has flourished. She builds things I never would have imagined. This toy has exceeded all expectations.
Three children. Three different ages. All obsessed. That alone makes it worth 5 stars. Nothing else in our toy closet pulls that off.
Not exaggerating. They genuinely prefer this. This is the toy that finally broke the iPad addiction in our home.
My 3 year old has thrown pieces across the room and stepped on them and they still work perfectly. Built to last. This thing is indestructible.
We had friends over and their children refused to leave because of this toy. Had to literally pry them away. Pretty solid endorsement I think.
If you're choosing between the small and large set, I'd go for the large one. We ran out of track pieces quickly with the smaller set.
My kids wake up asking to build tracks instead of asking for tablets. Best parenting investment I've made this year. This has completely replaced screen time in our house.
I've spent hundreds on toys over the years. This is the only one that lasted more than a month of consistent play. Should've bought it sooner.
My girl's concentration has improved so much since we picked this up. She focuses intently on building and planning her tracks.
Bought this for our road trip and it kept both children entertained at the hotel for HOURS. Lifesaver.
The usually-bored 8 year old in our house told me this is cool. From him that's basically a standing ovation.
Had to buy a SECOND set because the fighting over pieces was out of control. That's either a terrible review or the best one depending on how you look at it lol
The bigger set has enough pieces for both my boys to build together. They've been working as a team, which is lovely to see.
My 7-year-old documents his builds in a notebook. This toy has inspired him to think like an engineer. Absolutely good value.
The kids were completely absorbed. It's rare to find a toy that works for 3 year olds AND 6 year olds but this does. Already ordered two more sets for the school. I'm a preschool teacher and I brought this to my classroom.
My 4-year-old twins share this beautifully. They take turns building sections and cheer together when the car completes the track.
My 6-year-old spends his free time designing new tracks. He draws them out first then builds them. It's sparked an interest in engineering.
My girl enjoys creating and the train runs smoothly on all her designs. Nice magnetic building set.
Recommended this to my mom group and got about 12 thank you texts within a week. It's that good.
My kids never get bored because they can always build something new. Best toy investment. The modular design is genius.
My boy has learned a lot about physics through this toy. He experiments with slopes and curves to make the train go faster.
My twins share the Pro set and it's brought them closer together. They collaborate on designs and cheer when the car makes it through. Heartwarming to watch.
Good magnets and colorful pieces. Gets regular use in our house. Would be 5 stars with a carrying case. Solid screen-free option.
Makes a fantastic gift. I've now bought this for 3 different birthday parties and gotten thank you notes every time.
Good not outstanding. Quality is there and the concept is fun. My boy builds tracks most afternoons. I just think the base set needs more pieces to genuinely shine.
We brought this camping and the kids built tracks on the picnic table all weekend. best camping trip we've ever had honestly
My kids build different tracks daily and never tire of it. This has been the solution to summer boredom.
My 6-year-old has developed impressive problem-solving skills with this toy. When his track doesn't work, he troubleshoots until it does.
My 5-year-old son has ADHD and this is one of the few toys that holds his attention. He can build tracks independently and feels so accomplished.
My 3-year-old watches his older brother build and then tries himself with the easier pieces. It's ideal for multiple age groups in one house.
I love that this toy grows with them. Started with simple tracks and now my boy builds intricate 3D structures. Excellent value.
My five-year-old builds a different track almost every morning. The magnetic pieces are easy for him to connect, so he doesn't need much help anymore.
My 5-year-old builds tracks before school every morning. It's become part of our routine and he loves it.
Best purchase for getting my kids off screens. They wake up excited to build new tracks. It's become their favorite activity.
He designs tracks, tests them, modifies them. It's teaching him the engineering process naturally. My 6-year-old plays with this for hours.
My 4-year-old daughter plays with this more than any other toy she owns. The magnetic pieces make it accessible for her age.
My 4-year-old can use this independently which is impressive. The magnetic connection makes it frustration-free. He gets so proud when his train completes the whole track.

My kids have built tracks going up walls and across furniture. The possibilities are endless. I'm genuinely impressed with the engineering of this toy.
My boy enjoys the engineering aspect and has learned about stability and balance through building. Good educational toy.
This toy has been incredible for developing my boy's spatial reasoning. He's gotten a lot better at visualizing 3D structures.
My boy enjoys figuring out different layouts. The pieces are durable and the magnets are strong enough that his tracks don't fall apart easily. Solid toy.
I'm amazed at how long this toy holds their attention. My kids have fun with it for 90 minutes straight. No exaggeration.
My 5-year-old son sits and builds quietly for over an hour. As a parent of a high-energy kid, this toy is a blessing.
My girl plays with it every single day. The modularity means she never gets bored. I was sceptical about another building toy but this one is different.
My girl designs elaborate tracks and the train handles all her wild ideas. Good purchase for creative children.
Now he asks to build tracks first thing. This toy literally changed our daily routine. My 5-year-old was stuck on his tablet constantly.
Love it.
10/10 would buy again.
Obsessed. My whole family is obsessed.
WHY didn't I buy this sooner.
Best toy purchase of the year hands down.
Yes! The train holds onto the track with magnets, so it keeps running along the underside of raised sections and up steep climbs.
Starter (84 pieces, 1 train) is a lovely first set, Builder (102 pieces, 2 trains) has more track for bigger layouts, and Mega (179 pieces, 3 trains) has enough for huge multi-level builds the whole family can join in on.
The blocks have magnets inside, so they click together without any connectors or tools.
