Tigers Vs Bulls

The jungle rivalry of tigers and bulls is now being played out on your phone.

Motive:
Tigers try to attack the bulls and will win when they have killed 6 of the 8 bulls. The bulls win by blocking tigers and win when the tigers cannot move anymore in any direction.

Rules
A tiger can kill a bull by jumping over an empty field onto a bull. Both tigers and bulls can otherwise move only one field left or right, or up or down at a time.

Points:
The lower the number of moves, the tigers or bulls take to win, the better.
