Are you tired to clear same color gems by switching neighbors? In old style, all gems only have one same color within itself. So dull nowadays!
While in 3D world, everything changes. A stone has 6 faces, and we color the stones with 3 different colors. Each color holds opposite faces. And the top face is the stones MAIN COLOR.
Click the grid to choose the stone, and drag it to neighboring grids, same row or same column; the stone move to the new grid, and rotate its main color at the same time. If three neighboring stones are in the same row, or same column, and their MAIN COLOR is the same, then these stones are cleared, and scored.
Light bulb, a helpful tool to make your game easier, click it to show hints if possible.
It is very different to traditional clear game, and you can rotate stones in wise.
Good Luck.
