places round !
A sheep can move one square forward (if this square is empty)
or jump over an other sheep.
Be careful ! to move backward is not allowed !
Click on the sheep you want to move. If you are stuck, click on
the button "New game" to start a new game.
When all the white sheep are on the right side of the screen and
all the black sheep are on the left side of the screen, you win
If you don't succeed, after a lot of tries, you can have a look

Good luck !
