Special Symbols

The game's logo is the highest-paying symbol. A combo of three of these special symbols pays 1,000 times your bet per line, the symbol itself has a unique feature. It serves as the Wild symbol and substitutes for the lacking symbols in any regular combo.

Therefore, if the Wild is the only symbol you have on the payline, you earn the payout for one cherry. The game's logo is also a multiplier:

  • If it lands near two identical symbols, the payout doubles
  • If the combination features two Wilds, the payout increases four times.

Symbols and Multipliers

You will come across four symbols on the reels. Three of them are regular and one is the game's logo. Regular symbols are classic pictures which form winning combinations. These symbols include:

  • Cherries which pay x10 multipliers
  • One, two or three block BARs pay x10, x25 or x40
  • Sevens pay x800

The game features special combos of regular symbols:

  • One cherry and any two symbols pays 2 times your bet per line
  • Two cherries pay 5
  • Any three BAR pictures 5

To turn the game in your favour, you need to land combinations as often as you can. You need to land high-paying combinations in the best case. To benefit from the game, you need to land cherries during each spin. They are equal to the cost of two spins in this case, covering the spin cost and earning the equivalent of one bet.

The higher the payout for a combo, the more you get in your account. You will both cover the expenses and gain benefit in this way.
