About Builder 3D
Builder 3D is a first-person building game that runs in your browser. Walk around a sunny meadow ringed by trees and hills, and put up anything from a garden shed to a two-storey house with stairs, windows and a tiled roof. Every piece snaps to a 2-metre grid, so walls line up with floors and roofs meet neatly at the ridge, and the materials are drawn with real surface detail: wood planks with grain and knots, rough stone blocks, red brick with mortar, smooth plaster, and roofs of shingles, slate or clay tiles. Your world is saved on your device automatically.
How to play Builder 3D
Aim with the crosshair and a see-through preview shows where the piece will go: green means it fits, red means the spot is taken. Choose a piece from the bar (floor, wall, window, door, pillar, roof, gable, stairs or fence) and a material, then click to place it and right-click to take it down. Floors go in the middle of a grid cell, walls on its edges and pillars on its corners; aim at the top of a wall to build the next storey or set a roof on it. Roofs and stairs face the way you look, and R turns them. Doors open and close with F, and you can walk up stairs and roofs. Start from scratch or let the game put up a sample cabin to build on.

Tips & tricks
- Lay foundations first: walls snap to the edges of the floor tiles.
- Use gable pieces under the ends of a roof to close the triangle.
- Switch to sunset in the menu to see your house in warm evening light.
