Cube

Cube is a clever and visually intuitive logic puzzle that blends spatial reasoning with color-matching mechanics. In this game, you control a 3D cube that rolls across a 2D grid—each face of the cube can carry a color, and the goal is to collect all the blue squares from the grid onto the cube’s faces simultaneously, using as few moves as possible.

The twist lies in how the cube interacts with the grid: every time the cube rolls onto a square, the color of that grid square and the color of the cube face that lands on it are swapped. This means:

• A blank (non-blue) face landing on a blue square picks it up.
• A blue face landing on a non-blue square drops the blue color back onto the grid.

You must carefully plan your path to gather all blue tiles without accidentally dropping them elsewhere. The cube can hold up to six blue squares—one on each face—and only when all are collected at once is the puzzle solved.

To play Cube Puzzle, start by selecting a puzzle type and size from the "Type" menu. Click "New" to generate a new puzzle.

Roll the cube around the grid, picking up blue squares onto its faces. Try to get all the blue squares onto the cube at the same time, in as few moves as possible.

Use the arrow keys to roll the cube, or click where you want it to roll toward. After each roll, the grid square and the cube face that come into contact swap colors: a non-blue cube face can pick up a blue square, but if a blue face rolls onto a non-blue square, it drops the blue square back down.

Once you've mastered the cube, you can use the "Type" menu to select other regular solids!
