Insert a half penny in the slot on the top right of the machine. Turn the handle, middle right, to release four balls. Turn the knob, bottom right, to bring a ball to the top of the playfield. As the ball falls through the pins, use the knob, far bottom left, to move the shield and aim to catch it. If successful, the first flag on the right will flip over and cover an enemy flag, thus showing a successful catch, and the ball will be returned to play again. The game can be won using just one of the four balls, as it is returned to play for a successful catch. The aim of the game is to catch any of the four balls five times and cover all enemy flags. If you get as far as the fifth flag, then you use the knob, bottom middle, to turn the final flag (Union Jack) to cover the German flag and a half penny will be returned to the cup at the bottom centre.
