Frog Leap Test Answer

There is a fun game at the link below, which is supposedly a Second Grade test in China. It seems remarkably difficult when you first set out to complete it, but the answer will soon become clear.

However, if you simply don't have the patience to figure it out on your own... here is what I came up with...

Assume the positions (stones) are numbered 1,2,3,4,5,6,7.

To solve the puzzle click on the frogs that are in these positions, in the order described below;
3,5,6,4,2,1,3,5,7,6,4,2,3,5,4

voila, you've completed the test.
