Stage One: Start With A Rainbow
If we were building an open-ended collection from scratch today, we would begin with a rainbow stacker. There is a reason rainbow stackers have become one of the most recognisable open-ended toys in the world. They are remarkably versatile.
Children use them for:
- Stacking
- Balancing
- Construction
- Small world play
- Sorting
- Imaginative storytelling
A rainbow can become a bridge one day and a mountain range the next. It can support toddlers who are learning basic coordination and older children creating elaborate imaginary worlds. Most importantly, a rainbow leaves room for growth.
It doesn't tell a child how to play. It asks what they would like it to become.
For many families, a rainbow offers one of the best returns on investment in the entire open-ended play category.
Stage Two: Add A Block Set
Once a rainbow becomes part of everyday play, the next addition we recommend is a quality block set. Blocks are often underestimated because they seem simple. Yet they remain one of the most enduring play materials ever created. The reason is straightforward. Blocks multiply possibilities.
Children can build:
- Towers
- Cities
- Roads
- Bridges
- Animal habitats
- Shops
- Castles
- Vehicles
And when blocks are combined with a rainbow, entirely new forms of play begin to emerge. The collection becomes more than the individual pieces. It becomes a system.
This is where open-ended play starts becoming truly powerful.
Stage Three: Add Building Boards
Building boards are often the next step because they dramatically expand construction possibilities. Suddenly children can create:
- Multi-level structures
- Roofs
- Bridges
- Platforms
- Ramps
- Roads
The rainbow and blocks gain new purpose. The collection becomes more interconnected. This is one of the key principles we encourage families to think about. Every new toy should increase the value of the toys already owned. The best collections are not built from individual purchases.
They are built from products that work together.
Stage Four: Introduce Loose Parts
Loose parts often generate a great deal of excitement among parents. And for good reason. They are incredibly versatile. However, we generally recommend introducing loose parts after the foundation pieces are already established. The reason is simple.
Loose parts tend to shine brightest when children already have structures, landscapes and environments to incorporate them into. Once blocks, rainbows and building boards are in place, loose parts can become:
- Treasure
- Food
- Currency
- Building materials
- Characters
- Decorative elements
They add depth and storytelling opportunities to existing play. Rather than being the starting point, they often become the finishing layer.
The Most Valuable Toy Is Often The One You Already Own
When families begin exploring open-ended play, there is often a temptation to focus on what comes next. The next rainbow. The next block set. The next loose parts collection. The next purchase.
But some of the richest play we've seen has happened immediately after a new piece is added to an existing collection.
Not because the new toy was extraordinary. Because it changed the way the existing toys were used. A building board can transform a block set. A handful of loose parts can completely change a rainbow. A simple addition can unlock dozens of new possibilities. This is why we encourage parents to think less about individual toys and more about relationships between toys.
The most successful collections behave like ecosystems.
Every new piece increases the value of the pieces that came before it.
