Grimm’s Rainbow Play Ideas: 15+ Ways to Play, Build & Imagine

If there’s one wooden toy that truly captures the magic of open-ended play, it has to be the Grimm’s Rainbow. Beautifully simple, endlessly versatile and made to grow with your child, this iconic wooden rainbow can become almost anything they imagine.

From ball runs and towering constructions to tiny worlds, colour games and imaginative adventures, there’s no single “right” way to play. So, whether your Grimm’s Rainbow is brand new or has been a much-loved part of your playroom for years, here are some of our favourite ways to bring it to life.

Why is the Grimm’s Rainbow so special?

There’s something rather magical about a Grimm’s Rainbow. At first glance, it looks like a beautiful piece of wooden décor. Then you hand it to a child and watch it become a bridge, tunnel, cradle, castle, mountain, road or something entirely unexpected.

Grimm’s Wooden Toys is a family-owned German toy maker known for its beautiful, tactile wooden toys and its focus on simple designs that encourage creativity and open-ended play. The Large Grimm’s Rainbow is made from 12 curved pieces of sustainably sourced wood, each with its own natural grain and character.

And that simplicity is exactly what makes it so special.

Why we love the Grimm’s Rainbow:

Beautifully made: Natural wood grain and beautifully considered colours make it a joy to have in your home.
Open-ended: There are no instructions telling your child what it should become.
Versatile: Build, balance, sort, create small worlds, invent games and tell stories.
Made to grow with children: The way your child plays with the rainbow can change dramatically as their skills and imagination develop.
A family favourite: It’s the kind of toy that can bring children, siblings and grown-ups together for a little building challenge!

The best bit? There really is no “right” way to play.

What is open-ended play?

Open-ended toys don't have a single purpose or a predetermined outcome. Instead, they give children the freedom to decide what happens next.

And the Grimm’s Rainbow is a wonderful example.

One day, your child might stack the pieces into a wobbly tower. The next, the very same rainbow could become a bridge for wooden animals or a tunnel for their favourite cars.

This kind of play gives children space to experiment, problem-solve and use their imagination rather than simply following instructions.

What can children develop through open-ended play?

As they play, children naturally practise skills such as:

Problem-solving: How can I make my tower balance?
Spatial awareness: Which piece will fit here?
Fine motor skills: Carefully positioning and balancing each piece.
Early maths: Exploring size, shape, colour, symmetry and sequencing.
Language and communication: Creating stories and explaining their ideas.
Creativity: Imagining new possibilities for familiar objects.
Concentration: Persisting when a construction doesn't quite work.
Confidence: Discovering, “I made that!”

Our tip: Resist the urge to show your child how the rainbow “works”. Instead, put it somewhere accessible and see what they come up with.

Sometimes the most wonderful play ideas are the ones you never thought of yourself.

What age is the Grimm’s Rainbow suitable for?

The Large Grimm’s Rainbow is recommended for children aged 3 years and over by Oskar’s Wooden Ark.

But one of the things we love most about a Grimm’s Rainbow is how the quality and complexity of play can evolve as children grow.

A younger child might be fascinated by simply moving, stacking and arranging the pieces. As they develop, the rainbow can become part of increasingly elaborate constructions, games and imaginary worlds.

As your child grows, try:

Stacking and balancing the pieces in different ways.
Sorting the arches by colour or size.
Creating simple bridges and tunnels for vehicles.
Building houses, castles and towers.
Adding animals and wooden people for small world play.
Creating elaborate ball runs and obstacle courses.
Using the rainbow as a prompt for storytelling and pretend play.
Combining it with other open-ended toys to create bigger, more complex worlds.

The Large Rainbow is also a wonderful toy for siblings to play with together. One child might build while another creates the story around it - and suddenly you have a whole little world taking shape.

A note for parents: Always follow the age and safety recommendations for the specific Grimm’s Rainbow you purchase. Different Grimm’s rainbow products can have different age recommendations. Oskar’s Wooden Ark currently lists the Large 12-Piece Rainbow as 3+.

Build, balance & create

Ready to get building?

The rainbow pieces are fantastic building materials because they can be stacked, balanced, bridged and combined in so many different ways.

And you don't need a complicated setup. A few wooden balls, cars, blocks or animals are enough to get things moving.

Try these Grimm’s Rainbow building ideas:

Build a simple ball run or maze
Create a simple 'bowling alley' using the rainbow pieces and send a wooden ball rolling through. Arrange the arches on their sides to create a circular maze or a snake-shaped run and gently push a ball along.
Build a tower
Stack the arches into a tall, wobbly construction.
Build bridges and tunnels
Use the arches to create roads and pathways for cars, trains, animals or little wooden people.
Build a house, palace or apartment
Combine your rainbow with blocks, building boards, dolls and furniture to create an entire miniature home.
Try a balancing challenge
How many pieces can you balance before your creation comes tumbling down? Can you find new and exciting ways to balance your rainbow arches? Remember: Falling towers aren't failures - they're part of the fun!

Imagine, learn & play

Perhaps the greatest Grimm’s Rainbow play idea is to stop thinking of it as a rainbow.

Because once children start imagining what those curved wooden pieces could be, the possibilities really are endless.

Create a small world

Add some animals, wooden people, natural treasures, fabric or little houses and see where the story takes you.

Your rainbow could become:

A mountain range for woodland animals.
A bridge over a river.
A tunnel through an enchanted forest.
A fence around a farm.
A magical castle for tiny people.
A bed or cradle for a doll or cuddly toy.
A cave for bears, dragons or dinosaurs.

Explore colour

The rainbow is also a lovely invitation to play with colour.

Try a rainbow nature hunt: head outside and see how many natural objects you can find to match each colour.

Or use Grimm’s Rainbow Friends, wooden balls or other loose parts for colour matching, sorting and counting.

Turn play into a learning game

You can introduce early learning concepts without turning play into a lesson.

Try:

Counting: How many arches are there?
Sequencing: Can you put the colours in order?
Comparing: Which piece is bigger? Which is smaller?
Patterns: Can you make a repeating pattern?
Balance: What happens if we move this piece?
Storytelling: Who lives inside your rainbow castle?
Language: Can you describe your creation using three words?

And don't forget the wonderfully silly ideas!

A Grimm’s Rainbow can become a hat, mermaid tail, rocking cradle, birthday cake or even a piece of fancy dress.

That's the beauty of open-ended toys: the only limit is imagination.

Still looking for inspiration? Here are a few prompts to leave beside your rainbow and see where they lead.

Can you build something taller than your teddy?
Can you make a road for your favourite car?
Can you build a home for an animal?
Can you make a bridge that can hold a wooden person?
Can you create a rainbow maze?
Can you build something without using the largest piece?
Can you make a symmetrical picture?
Can you build a tower and knock it down with a ball?
Can you create a magical land and tell us its story?
Can you combine your rainbow with three other toys to create something new?

And perhaps our favourite challenge of all: What can you make today that you couldn't make yesterday?

Let the rainbow lead the way

A Grimm’s Rainbow doesn't need batteries, flashing lights or complicated instructions. It simply gives children beautiful materials and the freedom to decide what happens next.

That's why it can stay interesting for so long.

Today it's a tower. Tomorrow it's a ball run. Next week it's a castle for wooden animals. A year from now, it might be part of an enormous imaginary world that only your child understands.

There is no right way to play with a Grimm’s Rainbow - and that's exactly the point.

So pop it somewhere your child can reach, add a few favourite toys, and let them take it from there.

Happy building, balancing, imagining and playing! 🌈
