Children's building sets, building sets for kids, and creative construction sets for Boys & Girls of All Ages

MindWare is the only source you?ll need to stock up on building toys for kids. From our patented Q-Ba-Maze marble run to our KEVA precision maple building sets your kids will be able to let their imaginations run wild. But our house specialty sets are just the beginning. From the 6-foot tall Chaos Tower to a K?Nex Mini Golf Set, we have building toys for kids of all ages and skill levels. The little guys will love the Wild Ways Stacking Animals, Straws ?n Connectors as well as our classic Marble Run.

Inspire creativity in kids of all age and skill levels with KEVA building sets. KEVA planks and blocks capture the imagination ... lengthening attention spans, deepening concentration and building excitement. It's no wonder that KEVA Building Sets have caught the attention of Mensa, DreamWorks and Destination Imagination. When it comes to inspiring young architects and engineers KEVA is a parent and teacher's dream come true.

Treat kids to lessons in power, force and momentum with the Demolition Lab and Blast Factory or the Demolition Lab and Quad Blaster for build-it-up and demolish-it-down fun! With the ZOOB Challenge and the ZOOBMobile Car Designers Kit you can put it all together and create vehicles and launchers of all types using STEM (Science, Technology, Engineering and Math) skills.

Q-Ba-Maze is a unique system of colorful cubes that interlock to form an amazing marble maze with a huge difference! Q-Ba-Maze 2.0 by MindWare lets kids create marble maze sculptures in almost any design ... buildings, extreme mazes, even animals! Best of all, Q-Ba-Maze is unpredictable because the steel balls can travel in any direction since each cube opens on two sides, creating a live demonstration of probability, physics and art all in one!

Building toys for kids that foster STEM (Science, Technology, Engineering and Science) are creating quite a buzz with in-the-know parents and educators alike. Building games for kids help them to boost concentration, critical thinking skills, as well as increasing architectural and engineering interests. You'll find building sets scaled your kitchen table, your family room or a classroom. And you'll find building toys that represent just about any interest your kids may have!

Both the K'Nex Double Doom Roller Coaster and the K'Nex Hyperspeed Hangtime Roller Coaster stand over three feet tall and will give your little builder's hours of architectural toy time. If Dinosaurs or Space are your young scientist's favorites - or if you happen to be a science teacher - Laser Pegs National Geographic Dinosaurs 24-in-1 Construction Kit or the Space 24-in-1 Kit are the perfect building sets for you. Or spark an interest in electronics with the colorful and interactive Snap Circuits Light Set.
