32 of the Best Lego Alternatives for Kids

Photo collage of alternative for legos.

I’m wading into this topic because my wife and I have two sons. Our oldest is 7 and the youngest 4.

I love LEGO. Our boys love LEGO. I’ve spent untold hours building kits and random stuff with my boys and will continue to do so. I’m not publishing this to deter anyone from buying LEGO. Instead, this list is meant to provide other options whether a budget is a concern or you’re looking for a building toy that’s a little different.

LEGO isn’t the only building toy in town. We’ve researched and bought (or suggested as gifts to family and friends) many alternatives to LEGO for our boys. I’ve used many. Not all, mind you, but many.

If for whatever reason you are looking for a LEGO substitute, this is the place for you. Before I get into the list, there are two considerations when considering LEGO alternatives. They are:

  1. LEGO Clones:  What I mean by this is the pieces are the same more or less but fall under a different brand. In fact, these actually snap with LEGO so they are a viable option (often cheaper) that can mix with your existing LEGO. The downside is lower resale value and safety concerns.
  2. Clickable or snappable toys:  Another approach to LEGO alternatives are building type toys that aren’t LEGO or all that similar to LEGO.
  3. Building toys generally:  These are alternatives in that they are building toys in general.

A. LEGO Clones (compatible with LEGO)

This first list includes all brands that are compatible with LEGO bricks. This is possible because LEGO lost its lawsuit with Mega Brands.

A few considerations to keep in mind when buying LEGO clones is resale value and safety.

While we’ve mostly bought LEGO brand bricks, we have bought a few kits under other brands. We have a local toy store that doesn’t sell LEGO but instead Mega Brands, so when there, that’s what we buy. They are compatible with LEGO bricks, so once done the kits we mix it all in the tubs.

When I went on a trip where I visited the Midway aircraft carrier in San Diego, I bought my son a Sluban brand Apache helicopter brick kit that was compatible with LEGO. I set out the kit I bought below under Sluban.

Here are compatible LEGO brick options:

1. Mega Brands

Mega Construx Primarys of the Universe Castle Grayskull

Mega Construx Primarys of the Universe Castle Grayskull. info.

Mega Brands is a Canadian toy company with several lines including Construx and Mega Bloks. Construx is for older kids and is compatible with LEGO bricks. Mega Bloks are compatible with DUPLO®.

Overall, people really like the Construx bricks. You can build nostalgic characters and sets like Primarys of the Universe and Teenage Mutant Ninja Turtles.

2. Sluban

Sluban AH-64 Apachi Helicopter - 293 Pieces in Original English Box 100% Compatible - Educational Toy - Building Blocks (M38-B0511)

We bought this for our son. It was a good kit. info.

Sluban is quite a bit cheaper than LEGO and they offer a wide variety of kits. However, for some kits, customers mentioned that the completed toy didn’t stay together well.

We bought a Sluban kit for our son and I thought it was pretty good and I’ve built many LEGO kits over the years. The helicopter above was solid and fun to build. If you like military stuff, Sluban offers a good selection of this.

3. K’Nex

K'NEX Dueling Racers


I’ve never used K’Nex but as you can see there are some clickable brick components to some of the sets. These clickable bricks do work with LEGO.

4. Kre-O

KRE-O Star Trek U.S.S. Enterprise Construction Set (A3137)


If Star-Trek is your thing, Kre-O is for you. The pieces work with LEGO. Other things you can build are Transformers and Dungeons and Dragons.

5. Laser Pegs

Laser Pegs 41012 Combat Copter 4-in-1 Building Set Building Kit; The First Lighted Construction Toy to Ignite Your Child's Creativity; It's Your Imagination, Light It Up


As you can see, the distinguishing feature of Laser Pegs is that the pieces are transparent and emit light. It’s a cool concept and adds a fun dimension to this LEGO alternative. Yes, the bricks work with LEGO.

6. Flexo

Flexo - Toy Building Brick Set with Flexible 3D Blocks - Free Play Educational Stem Learning for Girls & Boys - Kids age 6+ - Award Winning Design - Inventor Set Neutral Colours - 815 Piece Build Kit


Flexo clickable pieces work with LEGO. In addition to pieces clicking together, they bend so you can create bendable creations which is a welcome additional feature. I can see how having Flexo pieces in a collection would make for more interesting clickable brick creations.

7. BanBao

BanBao Racer Maintenance Truck Building Kit (660 Piece), Yellow


For the money, BanBao looks great. I’ve never bought a BanBao set, but apparently it works with LEGO.

8. Bestoyz

Bestoyz Express Locomotive Trains Building Bricks Set, Collectible City Railroad Train Track Kit Toys for Kids (573PCS)

Click image above for pricing info.

Like BanBao, I’ve never bought a Bestoyz kit but it too works with LEGO.

9. LEGO Technic

LEGO Technic Bucket Wheel Excavator 42055 Construction Toy

Our son received this LEGO Technic kit as a gift and it’s amazing, but not easy. info.

While it’s the LEGO brand, the Technic building toy is something to consider as your kids get older. It’s advanced LEGO which can build some amazing things with motors and plenty of moving parts. It’s more complicated for sure, but the sky is the limit with what you can build.

B. Similar Concept to LEGO: Click or snap together toys

10. Nanoblocks

Nanoblock: Neuschwanstein Castle Deluxe Edition Set by Kawada


While Nanoblocks appear to be compatible with LEGO, they do NOT work with LEGO. The bricks are smaller and won’t snap to LEGO. The smaller bricks offer more detailed builds. Some of the architectural-inspired kits look amazing (I’m a big castle fan).

11. Meccano

Erector by Meccano Super Construction 25-in-1 Motorized Building Set, STEM Education Toy for Ages 10 and Up


Meccano has been around for a long time and it’s still a great building toy. It’s a bit more tedious having to screw or bolt pieces together, but it gives you plenty of functional building options such as the operational crane above.

12. Straws and Connectors

ZoZoplay Straw Constructor STEM Building Toys 800 Piece Straws and Connectors Building Sets Colorful Motor Skills Interlocking Plastic Engineering Toys Best Educational Toys Gift for Boys & Girls


Our boys have the straws and connectors toy. While simple, they use it quite a bit. It’s awesome for building fort frames. Kids as young as 3 can put them together but they don’t really get constructing anything useful until age 4 or 5.

13. Texo

Guidecraft Texo 100 Piece Set - 3D Geometric Designs Educational Interlocking Shapes- Architectural Building-Bricks STEM Toys for Kids


I’m unfamiliar with Texo but it’s a straightforward wood building toy.

14. ZOOB

ZOOB 250-Piece Set


Our oldest son played with ZOOB at various friends’ houses and he liked it a lot. I remember one time when he didn’t want to leave as he was engrossed in building a ZOOB creation. Because pieces are flexible via the connection, you can build bending, flexible creations which distinguish it from LEGO.


Arckit A10043 Go Plus 2.0, Kids Scale Model Building Kit


ARCKIT looks like a professional toy but it’s good for kids who like building realistic creations.

16. Qubits

Qubits Educational Building Set: 84 Piece for STEAM - STEM - Makerspace Classrooms and Library


Qubits is another building toy that can create all kinds of shapes and structures. Like all building toys listed here, it engages kids’ imagination. The pieces snap together and can bend once put together.

17. Brackitz

Brackitz Inventor STEM Discovery Building Toy for Kids Ages 3, 4, 5, 6+ Year Olds | Best Boys & Girls Educational Engineering Construction Kits | Creative Fun Learning Toys for Children | 170 Pc Set


As you can see from the above photo, Brackitz kits enable your kids to build fun 3D creations that actually work. I find the example of the Ferris wheel compelling because our son wanted to build a Ferris wheel with Technic LEGO, but the two of us couldn’t figure it out. Some kits come with pulley systems, which I can tell you from experience, is loved by kids.

18. Zometool

Zometool Creator 1 Construction Kit


If you child enjoys building 3D shapes, this could be a good toy for them. Based on researching completed projects, I didn’t find any completed projects you could play with, but instead, the fun is coming up with interesting shapes and designs.

19. DUPLO®

LEGO Duplo My First Bricks 10848 Colorful Toys Building Kit for Toddler Play and Pretend Play (80 Pieces)


When our oldest was 2 I was chomping at the bit to start building LEGO with him. I played with LEGO as a kid and couldn’t wait to jump back in. However, two-year-olds are too young for regular LEGO. LEGO’S solution is their DUPLO® line which is larger blocks. Both of our sons enjoyed this.

20. Green Toys Blocks

Green Toys Block Set, Multi


Green Toys Blocks are a “green” toy in that they’re made from recycled plastic and don’t contain BPA or PVC. You can wash them in the dishwasher. Great for very young kids.

21. Ever Block Systems

Ever Block Systems

Source: Ever Block Systems

I think Ever Block Systems, if you have the space, are awesome. Kids can build forts, walls, rooms, shelves, etc. The thing is you need plenty of space and they aren’t cheap if you want to buy enough to actually build something cool.

22. Bristle Blocks

Bristle Blocks by Battat - The Official Bristle Blocks - 112Piece - Creativity Building Toys Dexterity Fine Motricity - Bpa Free 2 Years +


In our house, we call Bristle Blocks “comb toys” and they were a hit when our sons were young. The pieces very easily connect together so that toddlers can build things pretty easily.

23. Polydron

hand2mind Polydron Geometry Shapes (Set of 92 pieces in 4 shapes)


Polydron toy kits create 3D creations which can be fun. If you have enough of them, you can build large structures which kids like doing.

24. Picasso Tiles (Magnet Building Toys)

PicassoTiles 60 Piece Set 60pcs Magnet Building Tiles Clear Magnetic 3D Building Blocks Construction Playboards - Creativity beyond Imagination, Inspirational, Recreational, Educational, Conventional


I don’t really see the appeal of magent toys but both my boys enjoy them when they get their hands on them. We never bought them any because some of their friends have them as well as a community center we frequent. I think they like the magnet aspect of them (magnets seem to fascinate kids).

25. Magnetic Tiles by Dreambuilder Toy


dreambuilderToy Magnetic Tiles Building Blocks Toys 40 PCS (Regular Color)


These magnet tiles are similar to the flat panel Picasso tiles above except these aren’t solid panels.

26. Marble Run by Marble Genius

Marble Genius Marble Run Starter Set - 130 Complete Pieces + Free Instruction App (80 Translucent Marbulous Pieces + 50 Glass Marbles)


While for slightly older kids (i.e. not toddlers), there are few kids who don’t like creating marble runs. Not only do they love building the run, but they enjoy playing with it once built. They can be challenging in that the creation needs to be designed so that the marble can successfully make it through the course, but not overly complicated that kids can’t figure it out.

Our oldest has a marble run set and loves it.

And here’s a more advanced marble run option by GraviTrax:

C. Other Building Toys

27. Wood Blocks

Melissa & Doug Standard Unit Solid-Wood Building Blocks with Wooden Storage Crate (Developmental Toy, 60 pieces, 5.25" H x 12.5" W x 15" L)


Our oldest son loved wooden blocks as a toddler. It doesn’t get any simpler than this, but he played with them daily building towers, walls, and whatever else inspired him. If you have a hard floor, get prepared for a lot of crashing blocks… it’s loud and jolting.

28. Matchbox

Matchbox 4-level Garage

info. Our youngest son has this garage and loves playing with it. It was his first Matchbox structure.

Our youngest son at the age of 3 and now 4, loves Matchbox tracks and structures. Not all kids do, but those who do enjoy them for hours. We were kinda clueless in the beginning as to the difference between Matchbox and Hot Wheels so we have both types. Our son doesn’t care. He loves playing with both of them.

The Matchox structures are fun for “real world” play while the Hot Wheels tracks (see below) are fun for racing cars and creating fun tracks.

29. Hot Wheels

Hot Wheels Corkscrew Crash Track Set

info. Our youngest also has this fun track. I enjoy playing with this as well trying to blast cars through the corkscrew track.

Hot Wheels tracks can be a blast because you fire out the cars from a launcher and see how well you can get through various track configurations. A good old game of smash up is fun too.

30. Wooden Trains

Thomas & Friends Wooden Railway Figure-8 Set Expansion Pack

Thomas & Friends Fisher-Price Wood, Tidmouth Sheds

Click images for pricing info.

I believe I’ve yet to run into parents in our neck of the woods who hasn’t bought their young kids some form of wooden train track system. There are several brands to choose from. Thomas and Friends is very popular and detail is amazing, but it’s the most expensive. You can also guy interchangeable track from Melissa & Doug as well as others. Thomas and Friends is the LEGO of wooden train sets, but you can get much cheaper options that are compatible with Thomas and Friends.

Over the years, our sons have built up quite a collection as a result of birthdays and Christmas’s. While I prefer building LEGO, our boys have spent countless hours creating cities and track configurations.

31. Play Mobil

Playmobil Camping Mega Set Toy, Multicolor


Play Mobil is a very popular toy. There isn’t much building to do, but you can mix and match sets to create some amazing scenes. We never bought them any Play Mobil because their grandparents have it so it’s nice to offer a novel toy when they go there.

32. Lincoln Logs

LINCOLN LOGS - 100th Anniversary Tin - 111 All-Wood Pieces - Ages 3+ Construction Education Toy


I was surprised to see that Lincoln Logs are still available. This was one of the first toys I remember having as a kid. We never bought them for our kids because they really liked the Thomas and Friends train stuff, but Lincoln Logs are a great building style toy that kids enjoy to this day.
