Click on any tile to rotate it 90°
At the beginning, each tile is randomly rotated by 90°, 180° or 270°

To achieve the ideal click count you can switch the rotation direction, by clicking on the left side of a tile you will rotate counter-clockwise and clicking on the right side will go clockwise.
