    Who is the manufacturer of the slot machine?

    Every slot machine must be manufactured by a company that invented, designed and put it into operation. Many players eventually find that they only enjoy playing on machines from specific manufacturers, so they narrow down their selection by preferred software manufacturers. In the Czech Republic, the most popular machines are from local software manufacturers such as Kajot or Synot.

    What are paylines and how do they work?

    Paylines on slot machines are imaginary lines that run through the reels of the machine and determine which combinations of symbols on these lines are considered winning. As the reels spin, players try to achieve winning combinations of symbols on these lines. Combinations must always start from the left. Each payline has its own payout value, and the winnings are determined by the paytable for each symbol on the particular machine. Modern slot machines can have hundreds of paylines, and players often have the option to choose how many of these lines they bet on.

Slot theme and symbols

At first glance, 81 Double is a classic fruit machine inspired by traditional slots from brick-and-mortar casinos:

  • When you win, the symbols will highlight and glow, which enhances the success of winning spins.
  • The soundtrack is quite minimalist, with basic mechanical sounds of the reels spinning and classic sounds of winnings.
  • Players who prefer clean and simple visuals without distracting elements will like this machine.
  • Despite being a type of fruit machine, you can spin WILD symbols here, which can appear anywhere on the reels and complete winning combinations.
  • In addition, you will have Mystery symbols available. If you spin them on the playing field, a random win will be waiting for you.
  • 81 Double offers an RTP of around 96%, which is a solid figure, but there are slots with much better odds.
  • game has medium volatility, which means that the wins don’t come like a treadmill, but you have to wait quite a while before you get a win.

WILD Symbols

The WILD symbol replaces all other game symbols. If a WILD symbol appears, it is fixed and the player is awarded three bonus rounds. If a new WILD symbol appears after a re-spin, it is fixed again and the player is awarded another re-spin. If no new WILD symbol appears, the game round ends. Wins are calculated on the base spin and each re-spin, with the total win being the sum of all these wins. If a WILD symbol appears on a payline, the win on that line is doubled (quadrupled in the case of two WILD symbols or multiplied by x6 in the case of three WILD symbols). Re-Spin is completely free.
