To change the direction of the gun and the searchlight move your finger left and right across the screen. If your finger is above the horizontal chain of 12 aircrafts, the gun will fire.

After you shoot down 12 aircrafts, the current round of the game will end and a number will appear on the screen showing the percentage of aircrafts you shot down. If no aircraft managed to hide behind the edge of the screen, this number will be equal to 100 percent. Click on this number to start the next round.

In each subsequent round, the speed of the aircrafts will increase, and the width of the searchlight beam will decrease. Click on the button in the top left corner if you want to disable this.

You can change the speed of the aircrafts with the top slider.

You can change the beam width of the searchlight using the bottom slider.
