The aim of this game is to reverse the order of the eight pieces. You may only move the pieces along the dark central channel. To move a piece touch it and move without releasing.
You may rotate the large circle in the middle, along with the pieces on it, through 180 degrees at any time by tapping the button under it. If a piece is only partially on the middle circle you won't be able to rotate the circle. A piece which is blocking the circle from rotating will appear slightly transparent.
The circle can hold a maximum of four pieces at any one time. Each rotation of the circle is counted as a move.
The lower row of smaller circles shows the colour sequence required. The upper row of smaller circles shows the original sequence.
