“Meeeeh!” Sheep are marching in a sunny day. A herd of black sheep and a herd of
white sheep meet each other on the bridge form different ends. Unfortunately,
the bridge was too narrow for them to pass by each other. Can you get over the
bridge before your fellow sheep player does?
1.Each player alternatively takes turns to move his/her sheep.
2.Only one sheep can be moved in a turn (unless they are stacked).
3.The first player to move all his/her sheep across the bridge wins the game.
