3D Tetris Box#

A 3D block slowly moves away from you into a 6 x 6 x 15 box. On desktop, use I / J / K / L for planar movement, F / D / S for rotation, and A for a fast drop.

The inward axis from the viewer’s perspective is the automatically descending z axis, and the camera is fixed as a slightly top-down perspective box.

Each piece is a 3D polycube made of four cubes. When a piece can no longer move inward, it locks in place, and any fully filled 6 x 6 plane is cleared for 1 point.

A 3D block slowly moves away from you into a 6 x 6 x 15 box. On mobile, use the X / Y / Z rotation buttons, the directional arrows, and the center D button for a fast drop.
