Slot machine details and review 81 Joker X
Game software developer Tom Horn Gaming brings another great title to the world of online gambling – 81 JokerX. This slot machine promises a mix of nostalgia with modern features, all wrapped up in an attractive design. If you like ornate slots with four reels and 81 payline mechanics, you can’t miss this treat. With every spin, you’ll fall in love with the slot machine more and more, and WILD symbols will help you do that. So don’t wait and spin!
Every slot machine must be developed by a company that invented, designed and put it into operation. Many players eventually find that they only enjoy playing on machines from specific software provider, so they narrow down their selection by preferred brand.
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.
81 JokerX will impress you with its simple but very eye-catching diamond theme.
The graphics follow both the card symbols and the luxurious diamond slot machines that we know from other slots and developers. However, it differs in its modern look, smooth animations and bonus features.
The game area is placed on an elegant dark background, which allows the symbols to stand out more. Overall, the visual design is very clean, clear and pleasing to the eyes.
The main attraction of this slot is definitely the mechanics of 81 win lines, because your chances of winning are really high.
We must not forget about the unique WILD symbols, which not only replace the winning symbols to make you win, but also bring you extra credits.
Depending on the number of WILD symbols that will be part of the win line, you will be awarded a multiplier from x2 to x8. And that’s something to say! Otherwise, the slot machine adheres to a rather traditional layout. So don’t expect any Scatter symbols, Re-spins or Free spins.
What you can experience here is the Gamble feature, which is improved. If you are afraid of losing your entire win from a spin, you can only risk half of it.
The game’s RTP is below average, but the volatility is medium. So you can look forward to smaller but more frequent wins.

WILD Symbol
The game is really designed very simply, so don’t expect any miracles. However, you will have WILD symbols available to you, which replace all other winning symbols and thus allow you to create new winning combinations even when you don’t expect it. If WILD appears on the game reels as part of a winning line, each win will be doubled. Depending on the number of WILD symbols, the multiplication of your winnings is x2.
For 1 WILD, the win is multiplied by x2
For 2 WILD symbols, the win is multiplied by x4
For 3 WILD symbols, the win is multiplied by x8
If your combination is made up of only these symbols, it will be paid out as the highest paying symbol in the game, which means that the WILD symbols will also function as the highest winning combination on the winning line.
Gamble feature with Joker and Take half
Players can double or quadruple their winnings in the Gamble feature. The feature also includes a Joker card that stands in for all cards. On the playing field, the player has three options – take the winnings and try gambling or take half. By taking half, the player is assured that in case of a loss, they will not lose the entire winnings.

Our rating of the game
81 Joker X
The online slot machine 81 JokerX by Tom Horn is a great example of how classic diamond slots can be combined with more modern features and elements. It is especially suitable for players who are looking for something more than just basic gameplay. The absence of Free Spins may be missed by some, but thanks to the special WILD symbols with multipliers, the game offers enough excitement and chances for a solid win. If you are looking for a simple but fun slot with multipliers, you should definitely give it a try.
