By swiping across the screen you can train to better tell left from right. Whenever the little frog sits in front of an obstacle you can see and hear in which direction the next lily pad to land on lies. By swiping in that direction you instruct the little frog to jump that way - either successfully landing on the pad or splashing into the water.
That way you are guiding the little frog to the big pond where it can re-join its friends – and on the way pick up as many lilies as you can.
