The first thing to do when talking about slot machines is to define them. As you may know already, these are part of casino gambling games that depend entirely on luck. The reels are usually three, displayed on a screen, and they start spinning as soon as the game begins. Nowadays, these can either be physical or not, activated by buttons or touchscreens. And only in the USA, they are extremely popular. Almost 75% of the casinos in the country make a profit from these slot machines. But why are they so popular?

Online slot games, in particular, are rapidly gaining popularity among lovers of games of chance. One of the reasons why users love online slot games is because they are, in essence, exciting, user-friendly video-games with interactive elements and attractive graphics.

Classical machines vs modern online slot machines

So, let’s understand the difference between online slots and the physical version of the game. The first one is related to the reels. In the past, they used to have only three but today the online versions feature more: up to five has become industry standard. And the other difference lies in the pay lines. Of course, the traditional machine only has one, but the online version can have hundreds of them.

Below, we list some further differences between these two types of games.

Special features

In general, classic slots do not present special features or icons. Different types of symbols, like wilds, might appear in a few older slots, but these symbols are much more common in modern video and online slots. But other types of icons like scatter ones or even bonus symbols are also characteristic of online slots. (For a detailed account of online slot symbols, check the next section)


These are accumulating prizes in money which grow and grow until a slot is won. When this happens, the jackpot starts again from zero dollars. Classic slots do not normally have progressive jackpots. However, they are very common  in most online games.

The main themes and design

Last but not least, the online and physical versions of slots are different in their thematic and visual design. Usually, classic slots don’t follow a specific theme, instead featuring the conventional slot symbols as imagery. Online slot machines, on the other hand, feature a wide variety of icons that follow different themes.

Slot machines functions, symbols and free spins

Modern technology has  allowed software companies like NetEnt to get creative and surprise us with stunning graphics and striking visual effects. Of course, the symbols that correspond to classic machines continue to exist, though today there are others more colorful, for example, that add to the design of these symbols. Let’s describe some of the ones you can find when playing.

Standard symbols are the traditional images that have always existed when it comes to this type of game, such as the Queen or the Ace. But in modern games, these symbols come with all kinds of 3D effects that make them more lively.

The wild type refers to the images that appear whenever a player strikes a bonus. And who doesn’t like that, right? Especially when you win after a long time. These wild symbols then to expand and become bigger whenever you find them among the reels. There are others called walking that stay on the reel for quite some time. They typically move across reels before leaving the screen on one of the sides.

Then, you can also find scatter symbols that are also related to bonuses. They are not easy to find and you will need at least 3 of them to finally get a bonus when playing.

For example, you can get free spins, a type of bonus given by online casinos to help you get more money spending less. The conditions for these free spins vary from casino to casino. For instance, some of them will be no deposit and some others will not.

Finally, the bonus symbols should not be forgotten. Here, most designers tend to experiment and try to keep these symbols related to the main theme. So, they are usually very visually impressive and are the ones who signal the juiciest prizes.
