The 6 toys here are grouped by what a 9-year-old does with them, puzzling, building, experimenting and playing, and each is read against its listing and its stated age range, as How we choose describes. Nothing here was handled or tested.

At a glance

Gravity Maze is the logic puzzle a 9-year-old solves alone

A logic game with a right answer suits the age when children start to enjoy being stuck for a minute. ThinkFun’s Gravity Maze is a falling-marble logic game: the player builds the maze the marble drops through. Its listing sells it for ages 8 to 12, so a 9-year-old has 3 years of challenges ahead. It suits a quiet afternoon more than a party.

Klutz Gear Bots and the Smartivity pinball are the building picks

At 9, a building kit can teach how a machine works, not only how bricks stack. The Klutz kit LEGO Gear Bots is a book with the LEGO parts to build gear-driven robots that move, sold for ages 8 to 12. It suits a child who likes to make, play and take apart, more than one who wants a display piece.

The National Geographic kits suit the child who wants an audience

Science and magic overlap at this age: both are about a result that surprises the people watching. The National Geographic Magic Chemistry Set builds 10 tricks out of chemistry, for ages 8 to 12. Plan on an adult nearby for the first few experiments. National Geographic also sells the Kids Magic Kit with 45 Tricks, for the same ages, which suits a child who wants to put on a show more than run an experiment.

What lost: drones, RC cars and light-up novelty

Drones and RC planes were left out: the RC plane in the search drew the weakest owner reception of any toy sold for this age, and the drone was too new a listing to judge. Light-up gloves and masks were left out by the January test: fun on Christmas Day, in a drawer by spring. For the year either side, toys for 8-year-olds and gifts for 10-year-olds have their own lists.
