A colourful birthday cake
Using the rainbow, semicircles, rainbow friends and building rings, you can create an imaginative cake in no time at all.
The semicircles can be stacked as individual ‘cake layers’. Balls can be used as little fruits or candles, and building rings decorate the cake like colourful sugar decorations.
The cake looks particularly lovely when rainbow friends are invited to the birthday party or when little glitter stones are added as sparkling highlights.
This way, you can create new cake variations time and time again – sometimes stacked high, sometimes very simple, sometimes brightly coloured.

A multi-storey car park with ramps and levels
Building boards and blocks are perfect for constructing multi-storey car parks.
The frames from the building sets form the individual levels, whilst building boards or semicircles become access roads, parking spaces and ramps. Cars roll into the building, or Rainbow Friends park their cars on different floors.
It becomes particularly exciting when children think for themselves:
How do you get to the top?
Where does the multi-storey car park need to be stable?
Which paths can balls roll along?
Often, new extensions spring up quite by chance in the process.


A castle with towers and gates
Building blocks become gates or grand castle entrances. Semicircles form wide castle stairways, and the frames from the building sets connect individual areas. Windows, towers and columns take shape through play.
Such structures come to life when Rainbow Friends move in. Balls can be treasures, building rings become crowns or decorations, and small loose parts transform the castle into an imaginative world.
Some children build in a perfectly symmetrical way, whilst others prefer a more playful, winding style. That is precisely the appeal: every castle looks different.


A ball run for experimenting
Ball runs often come about through simple trial and error.
Building boards are placed at an angle, rainbow pieces serve as tunnels or passageways, and building blocks help to create different heights. Then the testing begins:
Does the ball roll fast enough?
Where does it get stuck?
How can the track be extended?
What’s particularly lovely is that children can keep changing their designs. Often, a small ball run gradually turns into a whole movement landscape.





Imaginary worlds full of little details
Sometimes, rather than specific structures, children create little scenes and play worlds.
Rainbow arches become mountains or caves, building plates turn into islands, and semicircles become lakes or gardens. Balls, building rings and glittering stones add detail to the play.
It is precisely the combination of large building elements and small loose parts that opens up so many possibilities:
Laying out patterns
Creating paths
Hiding treasures
Inventing little play stories
And often, the world keeps changing as the game progresses.

Building is all about change
The beauty of building lies not in the finished result, but in the journey towards it. Towers topple over, building ideas change, and a cake suddenly turns into a castle or a ball run.
With open-ended building materials, new ideas keep springing up – sometimes planned, sometimes completely spontaneous.
And that is exactly what makes stacking and building so special:
Simple shapes are constantly transformed into new worlds.
