13 Free Spins

To run a bonus round of 13 free spins in the 13 online slot by Greentube, you need to catch 3 or more Scatter symbols designed as a black cat on the game screen.

If Wild appears on the screen during free spins, it remains in its box until a winning pattern occurs. And if during the round one Scatter stops on the reels, you receive an additional free spin. If there are three or more Scatter symbols, the round of 13 free spins is restarted.

They pay according to the bet that was set before the activation of this round. What's more, credits are not taken off of your account.

Symbols and Winning Combinations

A winning combination of 3, 4 or 5 identical symbols may land along a line after a reel-spin. A combo must be formed from left to right and start on the first reel. The list of symbols of the slot machine includes:

  • Playing cards "9" and "10" in a winning combination of 3, 4 or 5 identical symbols give multipliers of 10, 25, 100
  • "Q" and "J" - 10, 35 and 125
  • "A" and "K" - 15, 50 and 150
  • Tarot card and Voodoo doll - 20, 75 and 250
  • Doors with the number 13 - 25, 125 and 500
  • Mirror and magic ball - 35, 150 and 1,000

When calculating winnings, the multipliers of the above symbols are multiplied by the line bet. The reels of the slot machine also spin 2 special symbols:

  • Witch - Wild that replaces any icons in winning combinations except the black cat. The Wild symbol also has the multipliers of 10, 250, 2,500 and 10,000 in its own combo of 2, 3, 4 or 5 pictures. So, Wild is the top-paying symbol of the slot
  • A black cat is a Scatter that produces rewards regardless of the position on the reels. 2, 3, 4 or 5 Scatter symbols on the screen generate multipliers of 2, 5, 20 and 500. When calculating winnings, these multipliers are multiplied by the size of the total bet. If three or more black cats land after a spin, free spins with a sticky Wild symbol are activated.

Double-up Round

After a winning combination occurs, you are given the right to increase your winnings in the double-or-nothing game. To go to the round, click the Gamble button. The task of the double-up game is to correctly guess the colour of the playing card (black or red) in order to double winnings for a spin. In addition, the correct choice of the card allows you to continue the round or pick up the win using the Collect button.

If you fail to guess the colour of the card, your win will be lost and the round will end. It should be noted that the double-up round is not available in the auto spin mode.

How to Play the 13 Slot Machine

Before the first start of the reels, you need to set the bet and get familiar with the rules of the game. The panel for controlling the slot is found under the game screen and includes the following buttons:

  • Start - initiates one spin. If you hit this button during spins, the reels stop faster
  • Gamble - runs a double-up game if a winning combination lands after a spin. Thanks to this option, you have a chance to double your winnings
  • Collect - allows you to refuse the double-up game and continue spinning the reels
  • Autoplay - starts auto spins. In the auto spins mode, you cannot activate the double-up round
  • The "-" and "+" buttons in the Bet/Line section are for setting the bet on a line from 0.01 to 5 credits
  • "-" and "+" in the Lines section do not work because 10 lines of the slot are fixed
  • Paytable - opens a window with rules and payouts for combinations. It is important for you to take into account that the information on winnings in this window depends on the bet adjustment

The panel also displays the following windows:

  • Balance - displays funds in your account. At the beginning of the game, you are given 500 credits
  • Win - tells you the amount of the latest win
  • Bet - shows your current bet

Above the reels, you will find a button for adjusting the sound, as well as a small timer to control the duration of the game session.
