Rules of Space Invaders Slot

To win, it’s enough to collect from 3 to 5 identical symbols on the line. The linear range is fixed. This means that at any time of the game, all 10 paylines are active. Thus, before starting the spins, you only need to set the bet size. This is done in the following way:

  • Find the Line Bet menu at the bottom of the interface.
  • Set the value from 0.10 to 20 credits using the “+” and “−” keys.

It is important to consider that this setting controls the linear bet. Before the beginning of the spins, it will be automatically multiplied by 10, that is, by the number of lines. The maximum amount you can bet for each spin is 200 credits. You can start the spinning of the reels in two following ways:

  • Press the Spin button (the manual mode)
  • Press the Autoplay key (the automatic mode)

At the beginning of the auto spins, you can select their exact number from 1 to 99. There is no risk game or a progressive jackpot. There is a Turbo feature that speeds up the spinning of the reels.
