Slot machine details and review 40 Classic
The 40 Classic slot machine is a very easy and interesting game with precious stones that have been in fashion for several years. The manufacturer Casimi strives for simplicity so that their games can be played by both beginners and advanced players. The 40 Classic game features a 5-reel, 4-row game field on which you can spin up to 40 paylines in total.
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.

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
This slot falls into the category of classic games with a diamond theme, but on the other hand it has modern graphics, so thanks to the retro effects it definitely won’t get old.
Anyway, to secure a winning round, don’t forget to line up at least three, four and preferably five identical symbols in a row. Red, yellow or green gems, two-color BAR symbols or even blue and red sevens. For 5 blue sevens you get 10x and for red sevens 15x.
The volatility of this game is above average, Casimi offers an RTP of 92% to 96%. Your gameplay will be even more fun once you manage to spin the WILD symbol, which can replace all game symbols and appropriately complete the win line in your favor. I
n addition, you will come across two types of WILD symbols. The second WILD – the so-called Double WILD, which multiplies your winnings on a specific win line, and moreover, it only operates in Free Spins mode.
Your next salvation for winnings are the Scatter symbols marked as BONUS WHEEL. All you need are three of these bonus symbols to reach the free bonus rounds. The minimum number of Free Spins is 9, however the maximum number is 21, and with that you can win a lot! And believe me, these are not just any Free Spins.
During the bonus feature, the Double WILD comes into play, waiting to double your winnings.

Scatter Symbol
The Scatter symbol or BONUS WHEEL is the last symbol on the list of bonus and special symbols. Once you manage to spin 3 Scatter symbols, 3 bonus wheels will appear, where you will draw the number of Free Spins. You will get as many Free Spins as the sum of all 3 bonus wheels.
DOUBLE WILD
The second type of WILD symbol – the so-called DOUBLE WILD – can also substitute for all game symbols, also with the exception of the Scatter symbol. However, it only appears during the Free Spins bonus feature, when it doubles your winnings on the given line.
WILD Symbol
The game features two special symbols and one bonus symbol. The special symbols include two WILD symbols. The first of them is the classic WILD symbol that you know very well. It replaces all game symbols, except the Scatter symbol, to allow you to get the best possible winning line.
