The goal is to show only golden squares (yellow) with a number of moves no more than the indicated next to the words "Golden Rolly".
The color of the squares can be changed using the buttons on the sides: the buttons change the color of the squares in the same row or column according to the following rules:
1) a yellow square becomes the same color of the button;
2) a square of the same color of the button turns yellow;
3) a square with a color different from the yellow and from that of the button remains unchanged.
The presence of mirrors changes the row or column that is modified by the button.
The mirrors can be of two types: fixed or rotating.
