Here you can simulate the dynamic 9-rounds game, with one adjustment possible after rounds 3 and 6. At the beginning, choose the formations for both teams by pressing the arrow buttons. When you click the 'play' button, the play starts. Click this "play" button repeatedly until 3 rounds or 6 rounds are over and one adjustment is possible. After the game is over, by clicking the "New Game" button you start a new game. Again you can choose the distribution first.
