The circle is pressed before the yellow shape.


The shapes are square, diamond, circle, star and triangle.

Based on the clues; the colors are red, green, yellow, purple and blue.

The first to be pushed is not red, green, purple or yellow color. Then the first must be blue star.

The last which is yellow is not diamond, triangle or circle. So the last one is yellow square.

The 3 in the middle are purple (2), diamond (3) and circle (4). The circle (4) is green. Purple (2) is triangle shaped leaving a red diamond.


Change the colors of the shapes first by using the arrows.
