What are four-reel gaming slot machines?

As the title itself hints, four-reel slot machines have four independent reels. In comparison to three-reel slot machines, they usually have a higher number of possible winning combinations, i.e. more winning lines. In comparison to five-reel slot machines, on the other hand, they offer less complicated gameplay and sometimes fewer winning lines.

Four-reel slot machines are offered by the casinos and developers themselves usually less, mainly because of their reciprocity. Players are more keen on the uncomplicated fun of three-reel slot machines or the high variability of five-reel winning devices. Slot machine manufacturers themselves noticed this and quickly subordinated it to the business strategy. On the other hand, everyone knows that the group of fans that prefer this type of fun is smaller but way more loyal. Thus, high-quality four-reel slot machines will probably never die out.

Best free four-reel slot machines

Four-reel slot machines offer wider entertainment options and some slot machines from this category are more fun, i.e. much more popular amongst players. We bring you a list of four-reel slot machines that are the most popular on our site. If you are looking for inspiration for trips to the world of four-reel slot machines, you should definitely start here.

Joker 81

Joker 81 is at first glance a traditional four-reel slot machine by the company Kajot Games with fruit symbols and seven winning lines. However, it hides a treasure in its interior in the form of the Wild symbol. The Wild symbol has a great feature that makes it possible for it to replace any missing symbol on the playing field and activate the option to play on 81 winning lines. And all of that for the same money deposit! To unlock this feature, you just have to spin the Wild symbol in a way that the title “Joker” shows.

Multiplay 81

This slot machine by the company E-gaming is the epitome of the best features that the four-reel slot machines offer players. On one hand is extremely simple gameplay, where winnings are paid not based on fixed winning lines, but on a fixed number of matching symbols on each reel. To spice things up, there is also a wild symbol Multiplay 81 which increases the number of winning combinations to 81 and multiplies the total winnings value. As with any other slot machine from E-Gaming, you can play the Multiplay 81 slot machine on our website for unlimited time for free.

Turbo Slots 81

Turbo Slots 81 is a four-reel slot machine by the company Apollo Games that primarily does classic online slot machine games that you might know from brick-and-mortar casinos. Within playing the slot machine you will find classic and popular fruit symbols as well as BAR or Multiplier symbols, which resemble the oldest and most classic slot machines.

Multi Vegas 81

As the title of the slot machine hints, Multi Vegas 81 is one of the 81 family. They are slot machines with multifunctional Wild symbols, which, in the case of the correct star constellation (or symbols on the playing field), bring the possibility to play on 81 winning lines with the same money deposit as if you were playing with the original number of winning lines. Besides that, the Wild symbol also has a function that replaces all missing symbols. Multi Vegas 81 is thus a truly entertaining and exciting slot machine that every fan of slot machines should try regardless of his previous preferences.

Fruit Joker

Fruit slot machines are a diverse collection of gaming devices that bring something new every once in a while. Although Fruit Joker is not one of the pioneers, it contains a truly perfect graphic styling that stands exactly on the border between retro gaming slots and contemporary gaming slots. Fruit Joker has up to 4 reels and 81 fixed winning lines.

What pros do the four-reel slot machines have?

As said earlier, four-reel slot machines are some kind of amphibians in the world of gambling. On one hand, they still bring organized game principles that beginners can understand and that are not unnecessarily misleading. On the other hand, they offer a bigger space to create original game mechanics, which can potentially increase the game’s excitement.

Four-reel slot machines often offer for example bonus symbols with double function, thus they have an abundant representation of, for example, 81 machines, which offer an additional opportunity to play on a large number of winning lines with only a basic deposit. Because of this, this group of slots is an interesting store for all players who do not have a specific play style.

Bonus symbols and functions of four-reel slot machines

Slot machines with four reels are not as popular as other types of slot machines, for example, five-reel slot machines, however, they do not have fewer bonus symbols or functions. The most used symbols within this slot machine type are Wild, Scatter and add-on versions of these symbols, which usually bring two or more bonuses. One of these symbols is for example the Wild 81.

Wild symbol

The Wild symbol is a basic bonus symbol of all slot machines and it is on the four-reel slots as well. The Wild symbol has a function similar to the Joker, thus it replaces symbols, that you are missing on the playing field to get a certain winning combination. The Wild symbol can have more functions at the same time, in that case, it is a so-called “double Wild symbol”.

Double Wild symbol

The double Wild symbol is a combination of the basic Wild symbol function with other useful bonuses and functions, such as multiplying your winnings or adding winning lines. Among the most famous double Wild symbols is Wild 81.

Wild 81 symbol

The Wild 81 symbol is the most frequently used symbol, which comes to slot machines with two bonus functions. Firstly, the Wild 81 symbol, just as any other Wild symbol, has a replacing function and is therefore able to replace all missing symbols on the playing field. Secondly, it also added winning lines up to 81 (hence the name). At the same time, the winning lines are increased only during the game, which means that with the increased number of lines you play with the basic money deposit (you do not spend any extra money). It is thus no surprise that the Wild 81 symbol is so popular.

Scatter symbol

The Scatter symbol is the second most used bonus symbol right after the Wild symbol. If the Scatter symbol landed in the requested position or a number of symbols on the reels, it usually brings free spins into the game. The number of free spins depends on the game itself. You can always find out about the exact number of free spins awarded for Scatter symbols in the description of the game itself.

History of four-reel slot machines

Four-reel slot machines are the direct inheritors of the three-reel slot machines, although the real sequence (and the huge superiority in the number of fans and offered slot machines) was taken up to five-reel slot machines.

Four-reel slot machines were created because online casino developers were trying to offer customers a different gameplay and also find space to make their “advantage” bigger. Because of one added reel, four-reel slot machines now offer more symbols which leads to a higher number of winning combinations.

The first representative of this type of slot machine became a slot machine called Fortune Coin Company. The hotel Hilton on the Las Vegas Strip began to offer it in the year 1976. Since then, each year another representative of the four-reel slot machine is made, but just a few of them can reach as many people. Recently, the most famous slot machines are Multiplay 81, Multi Vegas 81, Simply the Best 81 and other representatives of the popular category of slot machines 81. A similar revolution just as the 81 slot machines did will likely come in the future with a different bonus symbol.
