Buying LEGO NINJAGO sets: a guide to mechs, dragons and minifigures

LEGO NINJAGO sets combine LEGO building toys with imaginative role play and action models with moving parts. But choosing the right set isn’t always easy for parents, relatives and collectors. A large picture on the box tells you little about the piece count, what’s included for play or how much space the finished model will need.

Three common buying mistakes are worth looking out for:

  • Age recommendations are underestimated: A set recommended for ages 9 and up may not be suitable for younger children, as it can include lots of small parts and challenging building steps.
  • Moving features are overestimated: Not every LEGO NINJAGO playset offers the same range of movement. Some models have just a few joints, while others feature moving wings, cockpits, weapons or rotating mechanisms.
  • Model size and piece count are confused: A large model doesn’t necessarily need a particularly high number of pieces. Specific figures such as 107, 821 or 1,707 pieces are a more useful guide when choosing than terms such as ‘huge’ or ‘epic’.

What to check before you buy

1. Age, building steps and small parts

The manufacturer’s age recommendation is a useful guide. Sets with larger starter elements and a manageable number of pieces are suitable for children aged 4 and up. For example, the LEGO NINJAGO set 71853 contains 107 pieces and a Starter Brick. Older children and teenagers may prefer more extensive NINJAGO building sets with several stages to complete.

Small parts can be a choking hazard. Always follow the safety advice, and supervise children below the recommended age when they’re using the pieces. Sets with 49 or 52 pieces are better suited as compact additions to a collection, while models with more than 800 pieces need plenty of time and a suitable space to build.

2. Play features and movement

When choosing a LEGO NINJAGO mech, look out for these features:

  • Moving arms, legs, shoulders and torso
  • Rotating elements or moving wings
  • A cockpit for a minifigure
  • Interchangeable weapons or parts
  • Additional vehicles, spinners or dragons

A model with several points of articulation can be posed in different ways. This is useful for role play and displaying it in a collection. If you’re choosing a LEGO NINJAGO dragon, also check whether its head, wings, tail and claws can move.

3. Space, storage and collecting

Before you buy, check the dimensions of the finished model. According to the product details, the dragon in set 71836 is 27 cm tall, while the dragon in set 71859 is approximately 28 cm tall and 38 cm long. These measurements can help you plan where to put it in a child’s bedroom or display cabinet.

If you already own several LEGO NINJAGO sets, check whether the figures, weapons and vehicles work well together thematically. Some models have parts that can be combined with other mechs, sold separately. For collectors, the number of minifigures, special characters, anniversary features and display appeal may matter more.

Frequently asked questions about LEGO NINJAGO sets

What age are LEGO NINJAGO sets suitable for?

It depends on the model. Some sets are suitable for ages 4 and up and include Starter Bricks and just a few pieces. Larger sets with 800 or more pieces are often designed for children aged 9 and up or for teenagers. Always use the specific age recommendation on the product page as your guide.

How long do LEGO NINJAGO playsets last?

How long a set lasts depends on how it’s used and stored, and how carefully its moving parts are handled. Replace any loose or damaged pieces, and protect finished models from moisture, direct sunlight and heavy pressure. For frequent play, simple, sturdy models are often more practical than delicate display builds.

Do LEGO NINJAGO building sets need batteries?

The LEGO NINJAGO sets mentioned in this guide are built and played with by hand. Features such as spinners, moving joints, cockpits and interchangeable weapons don’t need batteries. Even so, check the product description before buying if you’re expecting additional electronic features.
