Meet the set that turns little builders into young engineers. Thinkplay Gearphun Junior combines the sideways-clicking magic of classic Thinkplay blocks with real working gears, cranks, and chains, allowing kids to bring their creations to life. With about 300 bright, durable pieces, Gearphun Junior introduces the kind of cause-and-effect play that gets kids turning, testing, and tinkering nonstop.
Inside every set are colorful squares, triangles, joining bars, wheels, axles, driver gears, follower gears, and direction-changers—all the essentials for constructing a rotating-crane truck, a playful monkey, and a whirling helicopter. There’s even a hand-crank and chain-link system, so one twist of a handle brings a whole model to life. Kids can experiment with motion, gear ratios, and power transfer without realizing they’re learning the basics of mechanics.
To keep the creativity flowing, Gearphun Junior comes with large, double-sided instruction sheets printed with full-color, model pictures that build confidence from the very first project. Builders start with simple models and work their way up through smart gear-driven designs, incorporating hands-on lessons in balance, sequencing, and design that feel like playtime discoveries. By the end of the book, kids will wonder what else they can power with gears!
The learning value runs deep: Gearphun Junior strengthens fine motor control, hand–eye coordination, logical reasoning, and patience—all while showing how gears make motion possible.
Every piece is made from strong, washable plastic and stored in a sturdy, lidded tray or tub, keeping all the gears, cranks, and connectors neatly corralled when the day’s building is done. The pieces are fully compatible with other Thinkplay sets—so families can mix and match for even bigger projects.
Don’t worry if the colors differ from the instructions—it’s a great chance to blend creativity with problem-solving. Recommended for ages 5–9, ThinkPlay Gearphun Junior meets European toy safety standards and brings motion, logic, and creativity together in one satisfying click.
