Free 3D island · your avatar
Dress a blocky avatar, walk a sunny island, find eight stars, and build in twelve colors.
01 — Story
Blocky Sandbox is a small 3D island with no timer and no way to lose. You design a blocky avatar first: skin tone, shirt, trousers, a hat (cap, crown, top hat, party hat, or halo), a face, and a name. That avatar is saved on this device and is also used in Sky Parkour 3D and Gem Tycoon.
Eight golden stars sit on hills, behind trees, and on the stone stairs. The counter at the top tracks how many you have found. Walk with W A S D or the joystick, jump with Space, and drag to turn the camera.
Build mode is the B key or the brick button. Pick one of twelve colors and tap the ground or another block to stack. X or the eraser removes a block. G makes the avatar dance. Buildings save automatically, up to 1,500 blocks. Nothing is uploaded.
Open build mode, choose a color, and click or tap where the block should sit. Erase pulls it back off. Leave the page and the island is still yours next time.
