Software provider
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.

Reels
What are the Cylinders or Reels on a slot machine?
Reels are the basic element of most slot machines and are columns of symbols that spin and stop on the screen gradually during the game. They are therefore the basic element on which symbols spin and on which winning combinations are formed. The most popular numbers of reels are 3 and 5.

Winning paylines
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.

What is RTP
The RTP of slot machines is a rule of thumb for how much money a slot machine will return to players. Let's say you put 100 crowns in it, the RTP determines how much of that money you should get back. The average value is 92 to 97%.

Slot theme and symbols
At first glance, 81 Double is a classic fruit machine inspired by traditional slots from brick-and-mortar casinos:
- The graphics are simple, but also clean and modern. The symbols include classic fruits, sevens, bells and BAR symbols, which is a visual style that nostalgically reminds you of old slot machines. The animations are smooth and well-crafted, which contributes to the overall visual experience.
- 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.

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.
If you manage to land at least one MYSTERY symbol on any of the middle reels (reels 2, 3 and 4), your win is multiplied by 1 to 15. The total number of MYSTERY wins is multiplied by the number of MYSTERY symbols on the three reels, and the total win is the sum of the individual MYSTERY wins.
