Construction Set: 3D Builder

In Construction Set: 3D Builder, you put together 3D models from pieces of different shapes, just like with a real construction set. There are over 200 different parts, from small blocks to special roof and window elements. You can build houses, monuments, cars, and even characters. This 3D building puzzle game gives you step-by-step instructions for each model. Levels go from simple to complex, starting with small houses made of ten parts and moving up to full castles and robots. The game trains your logic and helps you better understand how objects are arranged in space.

How to play?

First, choose a model to assemble, then a diagram with instructions will appear. Look for the right pieces among all the parts and place them in the correct spots. Each piece has to match the diagram exactly, or the model will not come together. You rotate and connect the pieces just like in a physical construction set. If a part fits, it snaps into place. If it does not, try a different piece or rotate it.

Every model you complete stays in your collection. You can rotate your finished structures, view them from all angles, and enjoy the results. Some models move or light up after you assemble them, which makes the building process even more engaging.
