This is a strange game where you need to open circles with symbols. Your goal is to open the final circle with a symbol that looks like "A". All symbols except the last 1 are blocked.
To open a blocked circle you need to open the one that unblocks it. Place the mouse cursor over a circle to see what symbol unblocks it. If no symbol appears, you can click and open the circles. If you find coins under a circle click to collect them.
