If you have ever played slot machines, you have probably heard of a slot machine called 81. The number in this name represents the number of paylines, and this number is the most popular among players. One such slot machine is 81 Bubble Pop, prepared by the developers at Casimi. The game 81 Bubble Pop, which is literally famous among slots with 81 paylines, brings a fresh and modern environment and is sure to attract every player. At the same time, the classic layout of four reels and 81 paylines is maintained. There are also interesting features such as symbol removal and Mystery wins.
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.

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 81 Bubble Pop slot machine is practically a fruit classic. Winnings are calculated from left to right, but thanks to the number of win lines, it is not that difficult to achieve at least a small win. The controls are very simple, and if you have played Casimi games before, the game will be exactly as you expect. However, even beginners will quickly get used to the game, because nothing is complicated.
All the symbols in the slots are classic – fruit. In addition to fruit, you will also find a number of card symbols that you know from other slot machines – as is customary with Casimi slot machines, there are a total of eight winning symbols in this game.
You will get the biggest wins when you collect four star symbols, which offer a multiplier of up to 20 times your bet. The star symbol is followed by other fruit symbols.
Like almost all 81-type slots, the 81 Bubble Pop game does not offer bonus features, but you will find some here.
Among them is a special WILD symbol, which has the classic task of replacing game symbols. Instead of the Scatter symbol, there is a Mystery symbol, which in the form of a question mark brings a multiplier of the win from x5 to x80, so you can look forward to random and relatively high rewards.
In addition, there is a Respin bonus feature, which works as a Cluster function. This means that when you win, the winning symbols disappear from the game field, the others move to their places and new symbols attack from above. This way you can get several winning lines in a row.
