The goal

Build cubes to score as many points as you can before the clock runs out.

What is a cube

A solid block of a single color, the same length on every side: 2×2×2, 3×3×3, 4×4×4, and bigger.

Scoring

The moment a cube is complete, you score. Bigger cubes are worth dramatically more: a 3×3×3 is worth about 8× a 2×2×2, and a 4×4×4 about 4× a 3×3×3.
Cubes stay on the board after they score, so you can keep adding blocks to grow a cube into a bigger one and score again for the bigger size.

Each turn

1. A piece appears at the top.
2. Move and turn it to line it up.
3. The white shadow on the floor shows where it will land.
4. Press DROP. It drops straight down and locks in place.

Controls

On-screen buttons, or keys: Arrows move · R/F raise & lower · Q/E turn the view · A/S/D turn the piece · Space drop. Drag to look around, scroll or pinch to zoom.

Tip

Keep blocks of the same color together so they form cubes.
