Say yes: Endless Fun for Kids and Parents!
We bought the PicassoTiles Marble Run 100 Piece Magnetic Tiles as a present for our 3.5-year-old son—and I have to admit, he’s not the only one enjoying them! Think modern-day Mouse Trap meets magnets. He already had a set of PicassoTiles and loves building, so this was a great extension. I was initially concerned that the marbles might be too small, but they’re actually larger than traditional marbles, which was a relief. I still would make note of this for younger kids who are prone to putting random things in their mouths. The colors of the tiles are vibrant and fun to mix and match, adding to the overall play experience. The included photo inspiration booklet is a great touch. My son and I have had a lot of fun recreating the pictures, and then adding onto them to make new, more complex structures. It’s a great way to spark creativity and problem-solving. The only downside is that the stacking and attachment process can be a bit challenging for a 3.5-year-old. It’s definitely more of a team effort at this age, but that’s also what makes it a great bonding activity. One thing to note: the clear tube pieces are a little fragile—we did break one early on, so it’s worth being careful when assembling or taking things apart. We enjoyed this set so much that we ended up buying another for our soon-to-be 5 year old nephew’s birthday. If your child enjoys building and imaginative play, this set is a fantastic choice. Highly recommend!

Great marble run for littles
Great marble run, perfect for younger kids because the marbles aren’t super small! You can use other magnetic tiles you have for the bases which allows you to make the run bigger if you want. One of my son’s (3 yrs old) favorite toys! Only “complaint” is they are kind of a pain to connect/disconnect but I assume that design is intentional so littles cannot easily destroy 😂

Could be improved.. but still fun.
This is a lot of fun but the pieces are A very difficult to snap together and a few have already broken where the tabs click into the holes. I wish there were a few more downward ramp pieces so you can build a taller structure. Lots of straight pieces and the marbles lose momentum quickly.

Tips on building with Picasso Tiles
My 4 year old great grandchild and I played with the marble run set for nearly two hours on the day the kit arrived. He already had the 100 "classic" set of Picasso tiles. When we discovered it was too difficult for him to attach the chutes to the special tiles, he was easily recruited to build boxes for height and to contain the marble at the end of the run. Hints for building a complex marble run. 1) The chutes don't attach or detach easily to the tiles even for an adult. That is good for the stability of the structure but bad for new designs. To detach the chutes from the tiles, you can use an old hotel key card or an expired credit card to lift up the end and gently pry the chute off the tile. 2) If there are enough of the tiles with the hole in the middle for your design, attach a tile to each end of the chute. Then you just need to rely on the magnets to attach different chutes to each other. Or build several sections with several chutes within the section and both section ends end in a magnet tile. Then you just connect the sections together using the built in magnets rather than having to attach a chute to a tile. This is especially important when building at several elevations. This will allow you to rapidly change the configuration. If you run out of the tiles with the hole in them, first priority for one tile on each end are the small curved chutes and the ones for changes in elevation. For really simple runs, using only ten chutes, you can attach each to two tiles with the hole in them and rapidly change your designs. (There are 21 tiles with the hole in them in the 50 piece set. ) 3) Be sure to build a "corral" for the marble at the end of the run or arrange that the marble will drop into a box. Otherwise you are going to be spending a lot of time searching for the marble which seems to love to roll under the couch. 4) The chutes look and feel flimsy but in actual use they are quite strong. I don't advise it but I actually used a dull butter knife to pry apart a chute and a tile without damage to either. Then I discovered an additional use of a credit card! 5) For height form a tube with two of the longest chutes face to face. The resulting tube is much more sturdy then building boxes to place on each other with the plain magnetic tiles. 6) The long curved green chutes are made to match the height of two magnetic tile boxes of the standard small square tiles in the Picasso set. 7) The small curved chutes fit perfectly within a box made from the standard small square tiles. 8) To involve the younger child in the building process, ask them to help build boxes from plain tiles to support the elevated chutes and to embellish the design by adding on "roofs" and "walls" around the route. Or ask the child which way the marble should go next and build accordingly.

MAgnetic STEM toys
My son loves these magnetic tiles. The tiles are durable, and sturdy with different shapes and variety of bright colors. It came with two bases with wheels. It’s a great learning tool. The magnets are same size and actually feel the same as Picasso tiles but better than Titan tiles in which the magnets are thinner. Help to strengthen fine motor skills, collaboration skills, creativity and imagination. The Magna-Qubix are great too. They are much easier to carry than magnatiles since they are small. Helps my son with building skills. Magnets are smaller that magnatiles but works better than the tiles. It’s a better learning tool for basic concept of 3D shape The size is perfect for basic math. They are also compatible with BMAG, Titan and Picasso Tiles. The Picasso Magnetic marble run is awesome. You have huge number of possibilities for creation. Good for hand-eye coordination This is my son favorite. Also compatible with Magnatiles and Qubix. All of them are translucent and great for sensory play with light tables. My 3 years old son is having a blast and learning with these STEM toys. I highly recommend any of these set to any parents out there. Happy toddler = Happy parents = Happy customer

Perfect for gifts
Got these as a Christmas gift for a 7 year old. Loves building different designs out of these & watch the marble go. He gets very creative useing other things to hold up prices. I thought the price was great for what you get! The quality is very high I think.

Can be difficult to assemble
I bought this as a gift for my nearly-5- year-old granddaughter, who has a large set of Magnetiles. To assemble a run, you attach the marble run (gutter-shaped) pieces on either side of the square magnetic tiles with small compressible pins. It's not consistently easy to attach and detach the pieces, even for adults. To make things easier for young children to design their marble runs, you can attach the marble tracks to the square pieces ahead of time and let the child use the magnetic squares to put together a run. I'm hoping the pins on the gutters loosen up over time, to make using this set easier. The gutter pieces are somewhat fragile so breakage is almost inevitable. I'd rate this higher if it was easier to use out of the box. It's great conceptually and if the plastic pieces don't break, the set could be a wonderful long-term toy.

Really Fun Set, But Needs More Connector Walls
Fantastic fun with lots of creative potential and it pairs well with our other magnetic tile sets, allowing us to add a marble run to our existing towers, castles, etc. My only critique is that the set could use about twice as many of the connector walls (i.e., the pre-drilled wall panels with holes that receive the tube sections). Connecting a wall to both ends of a tube section allows plug-and-play building, making it easy to swap pieces in and out and experiment with different layouts. But, as it stands, there aren't enough connector walls to incorporate all the tube pieces... and you end up daisy chaining sections together, which sucks. The lack of connector walls limits the size and complexity of runs you can build leaving many of the included tube sections unused. Does anyone know if it's possible to buy additional connector walls separately?

Leuk speelgoed
Voldeed aan verwachtingen. Al een leuke baan gebouwd. Alleen zal moeten blijken hoe sterk de plastic clipjes zijn die aan “baan” stukjes zitten en die je in de vierkantjes “klikt”

Genial!
Son compatibles con otros bloques de construcción magnética, lo que permiten hacer pistas mas altas.

Great STEM toy!
My son loves this! he is still a bit young - I think 4 or 5 is a better age, but he loves it when we help him!
