Cube

Roll the solid to collect every blue square on its faces. After each roll, the bottom face and the square it touches swap colours: an empty face picks up blue, while a blue face puts blue down on an empty square. Try to fill every face in as few moves as possible.

Choose Cube, Tetrahedron, Octahedron or Icosahedron for the next puzzle. On triangular grids, only three edges lead to neighbours; the direction controls show one choice per available neighbour. Clicking anywhere on the board rolls towards the pointer, one square at a time.

Face numbers describe the current orientation. Board details identifies the visible and hidden faces, including the bottom face. Undo and Redo retrace your moves; Restart returns to the same starting puzzle and can be undone. Once complete, you may keep rolling as a reward; the score keeps the winning move count. Cube has no upstream solver or hint feature.
