In the game War Grounds, we'll try to play a rather unusual strategy. Before you on the screen will be an ordinary notebook paper in a box. On it you will see two points. One will be red, the other blue. You will choose the side for which you will play. Your task is to draw a line on the sheet which should be longer than the opponent's. Alternatively, you can cross the line of your opponent with your line. And if your size is longer then you will destroy the enemy. So you will earn points and pass the game.
