16 pins stick out from the 4x4 field. You may click on any pin to push it down. You play turn-by-turn with your opponent. When some player pushes down the last 4th pin in the Line (row or column or diagonal of 4 pins), this player "finishes" this line and scores a point.
The player, who has "finished" more Lines wins the game. And the beautiful girl is waiting for your next victory to strip for you!
