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! Review: Great set, best value - Our grandkids were obsessed with these when we brought them over. I literally sat on the floor for 3 hours. We never get tired of playing and building. Such a good amount for the money, we had to get another one so we could go bigger! Teaches them design and how to be clever building with what they have. ## Features - MARBLE RUN STEM LEARNING IN ACTION: This magnetic tile marble run turns gravity, motion, and cause and effect into hands-on discovery as kids design layered raceways with slopes, funnels, turns, and rolling challenges. - DURABLE, CHILD-FRIENDLY MATERIALS: BPA-free, lead-free ABS plastic and smooth edges support everyday building, while durable magnets and weighted balls keep each magnet tile marble run ready for repeated experiments. - EXPANDABLE, VERSATILE PLAY: Use the PicassoTiles marble run set on its own or combine it with other full-size PicassoTiles collections to create taller tracks, castles, vehicles, and imaginative multi-level structures. - SKILLS GROW WITH EVERY ROUTE: Designed for ages 3+, this marble run toy supports fine motor skills, spatial reasoning, concentration, sequencing, problem-solving, coordination, and teamwork through solo or shared play. - COMPLETE 120-PIECE COLLECTION: Picasso Tiles marble run building blocks include 10 dynamic shapes, slopes, funnels, track components, and steel-weighted balls for colorful gravity-powered challenges at home or in class. ## Technical Specifications | Specification | Value | |---------------|-------| | ASIN | B0876FDMY2 | | Age Range Description | Kid | | Best Sellers Rank | #817 in Toys & Games ( See Top 100 in Toys & Games ) #3 in Marble Runs | | Brand Name | PicassoTiles | | Customer Reviews | 4.4 out of 5 stars 3,700 Reviews | | Educational Objective | Number Counting | | Item Dimensions | 14.5 x 11.88 x 4.75 inches | | Item Weight | 2.5 kg | | Manufacturer | Picassotiles | | Manufacturer Maximum Age (MONTHS) | 999 | | Manufacturer Minimum Age (MONTHS) | 36 | | Manufacturer Part Number | PTG120 | | Material Type | Alloy Steel | | Model Number | PTG120 | | Set Name | PTG120 | | Size | 14.5*11.88*4.75in | | Theme | Buildings | | UPC | 817338022907 749684523114 | ## Images ![120 PCS Magnetic Tile Marble Run STEM Construction Set Ages 3+ | 10 dynamic shapes, translucent track parts, funnels & slopes, steel-weighted balls, BPA-free ABS, coordination & spatial play - Image 1](https://m.media-amazon.com/images/I/81zPRCa-SvL.jpg) ## Available Options This product comes in different **Color** options. ## Customer Reviews ### ⭐⭐⭐⭐⭐ Say yes: Endless Fun for Kids and Parents! *by J***K on June 22, 2025* 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!

We never get tired of playing and building. Such a good amount for the money, we had to get another one so we could go bigger! Teaches them design and how to be clever building with what they have. ### ⭐⭐⭐⭐⭐ Tips on building with Picasso Tiles *by K***A on January 27, 2026* 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. ## Frequently Bought Together - PicassoTiles Marble Run 120 Piece Magnetic Building Blocks Magnet Tile Construction Toy Playset STEM Learning Educational Block Child Brain Development Kids Toys for Boys and Girls Age 3 and Up - PicassoTiles Motion Activated Marbles 4pc LED Light-Up Glow in The Dark Translucent Balls for Marble Run Race Racetrack Maze Magnetic Construction Magnet Tiles Building Block STEM Education Kids Toys --- ## Why Shop on Desertcart? - 🛒 **Trusted by 1.3+ Million Shoppers** — Serving international shoppers since 2016 - 🌍 **Shop Globally** — Access 737+ million products across 21 categories - 💰 **No Hidden Fees** — All customs, duties, and taxes included in the price - 🔄 **15-Day Free Returns** — Hassle-free returns (30 days for PRO members) - 🔒 **Secure Payments** — Trusted payment options with buyer protection - ⭐ **TrustPilot Rated 4.5/5** — Based on 8,000+ happy customer reviews **Shop now:** [https://www.desertcart.ro/products/200979303-120-pcs-magnetic-tile-marble-run-stem-construction-set-ages](https://www.desertcart.ro/products/200979303-120-pcs-magnetic-tile-marble-run-stem-construction-set-ages) --- *Product available on Desertcart Romania* *Store origin: RO* *Last updated: 2026-07-24*
