Love building with toy bricks? BLOX lets you build brick-style 3D models in your browser: bricks, slopes, arches, domes and more on a snap-to-grid build plate.

Every piece snaps to the grid, so walls line up and roofs meet cleanly. Rotate pieces, paint them any color and stack them as high as you like.
Model ideas to start with
Houses with pitched roofs, castles with round towers, rockets, race cars, lighthouses and windmills — the BLOX community page has example builds you can use as inspiration.
Challenges with a ghost outline
Daily and weekly challenges show a see-through ghost model to rebuild. It's a great way to learn techniques like stepped roofs and round shapes.
