Best Challenging Lego Sets For Tweens & Teens

I am not sure why Lego put an age rating of 18+ on their challenging Lego sets, but I can tell you we love them so much we use them as a supplement to our homeschool curriculum!

Assembling intricate Lego sets with thousands of pieces, such as the Daily Bugle or the house from Home Alone. Presents an engaging challenge that tests both patience and precision.

Now we are in middle school these are one of the best homeschooling resources!

I am going to share with you our top 6 Legos for teens in order of the number of pieces.

The best challenging lego sets that kids will actually love to build

Educational benefits of playing with Lego

The educational benefits of playing Lego are almost endless but here are the top 4 for us:

  • Lego is calming (if his ADHD flairs up, building Lego calms him down. Check out even more toys for ADHD kids)
  • It boosts resilience and perseverance
  • It helps with problem-solving
  • Lego teaches kids to think in three dimensions

I also believe that playing with Legos, especially building challenging Lego sets, is the reason my son is very good at coding. It requires similar skills that Lego has definitely helped with.

This is why building Lego is one of our best games for kids.

How to know if a Lego set is challenging?

It is not age rating, this completely confused me, and to be honest, I have no idea why a Lego set is ranked by age. The best way to know is simply to look at the number of pieces.

Each box shows the number of pieces on the front of the box. Personally, I would ignore the age rating on the box as it has little to no meaning to us.

As these are challenging Lego sets I would definitely advise you to get something that interests your child. It can take days to complete, or even weeks in the Home Alone case.

Where to Buy Challenging Lego Sets?

The only place I would buy this Lego is directly from the Lego store. The reasons are:

  • I know it is NOT fake
  • It is generally the cheapest price
  • I get VIP rewards, that is how I purchased the razor crest!
  • If an item is out of stock you can be notified when the item is back in stock. We did this twice for the Daily Bugle.
  • When I buy a large set like this there is generally a free item. It is currently a free vintage taxi.
  • Free shipping over $35.

Legos for Teens

In our homeschool, we exclusively opt for LEGO STEAM sets, which seamlessly blend science, technology, engineering, arts, and math. Below, you’ll find a list of these sets, ranked by the number of pieces they contain.

Lego Home Alone

Freddie is still building the Lego Home Alone Set and there are still another 6 bags to go. But the detail on this set is absolutely out of this world.

Daily Bugle

The Daily Bugle is possibly his favorite set apart from anything else it came with 25 Minifigures. However, it is super hard to get hold of, we were lucky (well with lots of stock notifications.) But if you can get hold of this too I highly recommend it.

Lego The Friends Apartments

Lego The Friends Apartments was a special set for Freddie as he recently watched all of the Friends episodes with me, and as I did he fell in love with all of the characters. We got this set after the Central Perk set (shown below.)

Lego Friends Central Perk

Lego Friends Central Perk was the first challenging Legos set we purchased which was when he was 10. But it has a lot fewer pieces in than the ones previously.
