When you activate the NIGHT TOWERS feature, you can choose an additional level of five, ten, or 20. The feature can start in two different ways: If your win is five times the level or more, a tower will appear over the reel set, on which the MERKUR sun will jump up. If it reaches the top of the screen (high striker function), you enter the feature. NIGHT TOWERS also starts when at least three “Towers” scatters appear anywhere on the reels in the base game.
