Why it fits a quiet break

Cube Worlds is for a longer, open-ended pause when you would rather make or explore something than solve a fixed board. There is more to learn than in a card game, but the sandbox format lets you set your own small goal. Try building one simple structure, then leave it there.

How to play

Use the keyboard to move and the mouse to place or remove blocks.
