Slot machines, also known as ‘one armed bandits’ or ‘fruit machines’, belong amongst the most popular games in any online casino. They differ in the game mechanics such as the amount of reels, winning lines or minimum and maximum coin size that can be used. Most players, however, choose their game based on the theme. Fantasy fans might fall in love with the Game of Thrones slot while those who prefer more classic games will probably like Reel Gems. To make finding of your favourite game easier we’ve collected the best ones and divided them into different categories. And don’t forget – these are free slot machines! So everyone can now enjoy many different gratis casino games online, free play slots and much more on CasinoHub!
Slot machines are one of the most modern games in the casino ensemble and only appeared on the scene about 130 years ago. Since their invention they have developed into one of the major choices at both land and online casinos. Over the past decade, hundreds of online casino operators have dedicated their offer solely to slots that have evolved substantially since the initial versions. Nowadays, on almost every casino site you can play free slot machines as well as their real-money version if you feel confident enough.
Types of online slots
To new players online slots might seem almost identical but in fact the differences are quite big. Some of them have higher payouts but don’t offer as many rewarding features such as free spins, special symbols or bonus games. On the other hand, progressive slots give the chance to win huge jackpots that often go up to millions of dollars.
Here are the three main types:
The main difference between classic online slots and video slots are the themes, the amount of reels and the amount of paylines. Many of the classic slots use the popular, fruit symbols, but you will find other variations as well. Classic slots though will have just 3 reels, a smaller number of paylines compared to video slots and less sophisticated bonus rounds and special features. On the flip side 3 reel slots pay out more often then 5 reel video slots but with smaller amounts.
Video slots usually have 5 and more reels and anything between 1 and over 100 pay lines. They have become the most common type played online also because of the huge variety of themes to choose from. They can feature anything from movie characters and popular TV shows to themes with their own story line and entertaining scenes. The basics of how video slots work are the same to the classic games but they often offer bonus games, free spins and special symbols that give further rewards. Some of them might have an unusual set of rules to make the game more interesting.
Progressive slots can be extremely rewarding and that’s why they belong amongst the most popular games. They come with large progressive jackpots that are formed by adding a part of every wager to the reward amount. So every time someone plays it the jackpot grows bigger until 1 lucky winner wins it all. Progressive slots can be linked across games, across machines and across casinos, so the total jackpot sometimes goes up to 20 million USD and even more. As soon as the jackpot in a progressive game has been won, the game is reset and the jackpot starts to get built up again. There is a wide variety of progressive slots games to choose from, each with a temptingly large jackpot once enough players have contributed to the prize pool. One of them is Mega Moolah that is known to be one of the most generous slots with a progressive jackpot.
Almost any online slot machine has some special symbols that are often referred to as ‘player’s best friend’. When they appear on the screen, in most cases, they mean an extra reward or they can even take players to a bonus side-game. However, not many players are familiar with their meaning and that’s why we’ve decided explain them:
Nowadays there many unique types of Wild symbols but the basic kind simply stand in for other reel symbols in play on the reels. Whenever one of them lines up alongside any set of other matching reel symbols it will help to form a winning combination.
Over the past few years, software developers have started making these Wild Symbols even more exotic. You can now find Expanding Wild Symbols, Sticky Wild Symbols or Shifting Wild Symbols and many different ones. Some of them can appear to cover the entire reel and when several of these appear on the reels, you prize will be huge.
Scatter symbols are basically a key to unlocking various fun bonus features designed within a slot game. Unlike symbols that have to be lined up on a pay line to win, the scatter symbol just has to appear on the reels to open up free spins, mini-games, or other bonuses. Scatter symbols are typically one of the highest paying symbols in a slot game and are represented by a specific graphic that is unique to the theme of the particular slot machine.
