Puzzle Location: Chancer Lane Corner (The chimney of the building in the center)
You have been given two very different-shaped stars.
The one on the left is a pointy star, and the one on the right is a flower-shaped star.
Can you use both of them together to make five circles?
Slide the stars to move them, and touch to rotate.
Touch and hold on a star to change its size from small to medium to large.
Only one of the stars needs to be rotated, and it can be either one.
Try lining up the centre of the stars as you place them together.
The pointy star should be small, which is the size it starts at.
The size of the flower-shaped star should be midium.
Change its size by pressing down on it.
The answer is as follows.
The round shape's sise is medium.
The jagged shape's size is small and rotate.
