Different types of slots

If you have ever visited a casino you know that the range of slots on offer is really huge. There are classic slots, advanced video slots and even 3d slots! But what exactly are the differences between them?

Classic slots

As the name suggests classic slots are digital adaptations of the well known slot machines. They usually have 3 to 5 reels with symbols on them. So these slots are the closest to the gaming experience of a traditional slot machine.

In classic slots you usually see the entire fruit machine on the screen, while in video slots you usually only see the screen with the various reels. Classic slots also sometimes contain two playing sections: one as the base game and one reserved for a bonus round. They usually do not contain special features such as bonus games and special symbols.

Video slots

Today video slots are the most popular and most played slots. The first difference between video slots and classic slots is that in video slots you usually only see the screen with the reels on it. The rest of the machine is not in view.

Since the game takes place on a single screen, a lot of attention is paid to the design of the video slot. That is why there are video slots with the most diverse themes, from famous movies like Scarface to video slots based on fairy tales or science fiction stories. Often all the elements of a video slot are completely themed. Something for everyone!

The differences

Most video slots have five reels that contain the various symbols. In contrast to classic slots the reels often have so-called winning lines running across them. When you manage to spin a winning combination of symbols on one of these winning lines you’ll be eligible for a win.

Video slots can have very many of these paylines on board. Some have as many as 40 separate paylines running across the playing screen. Playing on many active paylines at the same time of course also brings with it an increased chance of winning and this is precisely one of the reasons why video slots are so enormously popular.

Another reason for the popularity are the special features that you can find in video slots. There are Wild symbols that act as a joker and Scatter symbols that can earn you free spins. Often video slots also have special casino bonus features that can be very attractive. Due to the graphics they often look like a computer game in its own right and you can win some very interesting prizes.

3d video slots

The name 3d slots might be a bit confusing as you don’t need 3d glasses to play these slots. The word 3d in this case refers more to the animated parts of a video slot. This new kind of video slots is full of animations and so you really have a sense of depth.

While playing, graphic elements from the background can suddenly move forward suggesting a sense of depth. Who knows, maybe in the near future you will be able to play completely 3D video slots through virtual reality.

A brief history of slots

Slots are basically digital slot machines that you can play in the casino. They are based on the traditional slot machines that you used to find in casinos, hospitality venues and arcades. The history of slot machines begins in 1985. American auto mechanic Charles Fey invented the first mechanical slot machine, the Liberty Bell, in his spare time. His invention soon enjoyed enormous popularity and thus Fey was able to open his own Slot Machine Factory in 1986.

Since then, the machines have become increasingly popular. The emergence of new techniques allowed slot machine developers to apply all kinds of innovations to slot machines. In the 1970s, the advent of, among other things, the microchip made it possible to develop digitally controlled slot machines. This in fact inspired the modern digital slot machines that you will find in every casino.

When the internet boomed in the 90’s it became very interesting for casinos to enter this market. The number of online casinos grew explosively. Of course the popular slot machines could not be missed and thousands of different online video slots were developed. And that brings us to today where you can even play video slots on your smartphone or tablet. What the future of slots holds, that’s still a bit of guesswork. But if we look at history, slots will always be one of the most popular games in online casinos!
