Slot machine details and review Joker 81
The Joker 81 online slot machine is one of the other fruit classics. Its reels are decorated with the usual cherries, sevens, bar symbols and melons of old slots and a fruity mix of more recent additions such as plums and oranges. The tried, tested and very simple concept is reflected within the gameplay. The number 81 in the title refers to one special feature!
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 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.
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.

Themes
Each slot machine has its own design or theme that appeals to a specific group of players. If you want to play slots with fruit symbols 🍉 or with an Egyptian theme 🐫, no problem. Just choose and we will narrow down the selection of slots to your taste.
The volatility of a slot machine tells you how often and how big of a win you can expect - some slots pay out small wins frequently, while others pay out larger amounts less frequently.

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
The graphics are not bad, but could be better. The boring background is complemented by an abstract, but at the same time non-aggressive orange pattern, not to say that the creators have completely abandoned it. The symbols are well elaborated. The drawn symbols are immediately recognisable and are the right size. The soundtrack, on the other hand, is too restrained. You only listen to the clicking of the reels and the ringing of the bells that announce the activation of the 81 paylines special feature. However, for a theme with a fruity classic, we would have liked something more.
Joker 81 theme and symbols
Joker 81 is a four reel slot machine with seven paylines and one pay table for everything. A win is awarded for four of the same symbol on a payline. The standard gameplay is enlivened with a little variety. When the WILD Bar symbol lands on any of the reels, 81 paylines are activated. This means that you will have an additional 74 paylines at your disposal. However, the WILD has its classic feature and you can get up to 120x your bet for it!
Since you have to hit four symbols to win, wins are very rare and tend to be very small unless you manage to hit one of the grouped symbols and the WILD symbol. As a result, the variance is very high.

Our rating of the game
Joker 81
The Joker 81online slot game is clearly one of the fruity classics that have never contained more special and interesting features. And between you and me, that’s a great shame. Every player tries to multiply their wins and bet credits, but here it doesn’t work very well. If you’re looking for a smaller, relaxing game where you just spin the reels and watch the symbols, then this is the right slot.
However, you’ll have to put up with some very small wins. We’re sorry that Kajot didn’t try harder and the developers didn’t make the slot into something more interesting.
