Toy Design 2026: The Best Toys Are Unfinished

In 2008, the National Toy Hall of Fame did something that sounds like a joke but is one of the more profound statements in design history: it inducted the stick. Not a branded stick, not a stick with a chip or a movement — a plain stick, praised by curators as "all-purpose, no-cost," and admitted without even a formal nomination. Three years earlier the same hall had inducted the cardboard box. Two of the most celebrated toys in the museum are things nobody designed at all.

That is not a failure of toy design. It is its deepest lesson. As the Strong Museum's chief curator put it, "it's that empty box full of possibilities that kids can sense and the adults don't always see." A stick costs nothing and can become anything — a sword, a wand, a fishing rod, a line drawn in the dirt. Its power comes entirely from what it doesn't do. And that points at the single most important decision in toy design, made long before any feature: how much of the toy do you leave for the child to finish?

Child-development educators even have a ratio for it. They call it the "90/10 rule": a great toy should be about 10% toy and 90% child. The toy supplies a small, sturdy invitation; the child supplies the imagination, the story, the rules, the ending. Open-ended toys — blocks, balls, loose parts — have no fixed outcome and no "right" way to play, which is exactly why they never get boring. Wooden blocks, the quintessential example, become a castle, then a road, then a spaceship, and along the way quietly teach balance, cause and effect, and the patience to rebuild after a collapse.

Now hold that against the toy that does everything. A fully-articulated licensed figure that lights up, talks and plays its scene for you delivers a bright hit of delight — and then dies, because there is nothing left for the child to add. It has already finished itself. The design thinking behind the great toys is the opposite instinct: deliberate incompleteness. LEGO, also in the Hall of Fame, is the industrial expression of the stick — a system of simple parts that ships you a suggestion and leaves the building to you. The Montessori and Waldorf traditions formalised the same idea: trust the child, and design the toy to get out of the way. A single set of plain blocks can absorb years of a childhood precisely because it is never the same toy twice — the child redesigns it every afternoon, which is a kind of authorship no fully-finished toy can offer.

This is a concept-phase decision in the purest sense, because it cannot be fixed later. The level of "finish" is baked into the object's fundamental concept, not its styling. Once you have designed a toy that performs the play for the child, no amount of quality, colour or licensing can hand the child a role back. And it runs against every commercial instinct, because a toy that does more looks like more value on the shelf and demos better in an ad. Restraint is the hard, unnatural discipline — and it is the whole game. The best open-ended toys are the ones confident enough to under-deliver on the box and over-deliver in the hands.

The lesson generalises far past the toy aisle. Any product that wants to be used again and again, rather than consumed once, faces the same choice: how much do you finish for the user, and how much do you leave for them to complete? The tools people genuinely love — a great instrument, a flexible piece of software, a plain notebook — tend to be 10% tool and 90% person. The ones that dazzle and then gather dust usually did all the imagining themselves. Designing for participation instead of consumption is a decision you make at the very start, or not at all.

At Depix, this is why we treat restraint as a concept-phase discipline, not a compromise. The stick has been a favourite toy for as long as there have been children, for one reason: it trusts the person holding it. The best design has always done the same thing — it leaves something unfinished on purpose, and hands you the rest.
