The SlotsMate Guide To Free Online Slots

How Do Online Slots Work?

We all enjoy spinning the reels and the seemingly simple mechanics of slot machines, but the truth is that there’s a lot going on behind the flashy pictures. Online slots are based on a random number generator (RNG), which works continuously in order to ensure the game stays fair and offers the same odds to all players. Basically, there’s a lot of complex mathematics which works towards making the spins as random and unpredictable as possible. Another thing influenced by math is the payout, also known as Return To Player (RTP), which represents a predefined percent of the wagered money that is won back by the player, RTP generally ranges between 82% and 98%.

TYPES OF SLOTS 
Today, slots come in all shapes and sizes. From the classic slot machines which remind of the land-based casinos to the modern and refreshing feel of video slots, you can find on this page a wide variety of pokies. We will be discussing the most popular categories of pokies below:
 

  • Video Slots: These modern pokies make up the most of our Free Online Slots list and are the most popular slot machines due to their complex mechanics, various special features and symbols and, of course, beautifully-designed 3D slots graphics. You’ll notice some well-known titles making an appearance here, as well as some unique and innovative designs such as Finn and The Swirly Spin, a NetEnt creation whose trailer you can watch below:
     
     
  • Classic Slot Machines: With their old-times feel and simplistic interface, there’s no wonder that players still enjoy going back to the originals every now and then. It seems that, among the favorites, you’ll encounter classic slots such as Lucky Streak 3:

  • Penny Slots: Even if you’re playing on a budget, there are plenty of penny slots you can enjoy! That means you can find games which allow you to bet as little as one penny per line, making them perfect in case you don’t feel like wagering too much. Among these, you’ll notice Wu Zetian, Warlocks Book, and Halloween Jack. You’ll be surprised to find out how many pokies can be played for a really small amount of credits!
     
  • Mobile Slots: Thanks to the advancement of technology and the increasing popularity of mobile gaming, you can now enjoy slots from wherever you may be: your couch, the park or even the beach! Most modern slots work on smartphones and tablets, due to the fact that they’re based on HTML5, which allows them to run natively across platforms and operating systems.

SLOT FEATURES
Today, online slots have many different features, which are entertaining and rewarding at the same time. From special symbols which brings opportunities for extra credits and bonus features, there’s a lot to look forward to when playing online pokies. Here are some of the most popular slot features:
 

  • Free Spins: This concept was first coined by Net Entertainment, and quickly became one of the most popular features in the world of online slot machines. Today, most, if not all the modern slots have the free spins feature, which allows players to play a number of rounds without paying, while they get to keep the winnings!
     
  • Bonus Rounds: These special events which occur during gameplay are an enjoyable break from the spinning reels. They can come in many shapes and sizes, from wheels of fortune to more interactive minigames. There are even slots which feature both the aforementioned free spins and other types of bonus rounds, such as Microgaming’s Tarzan. If you want to see what we’re talking about, check out the slot’s official trailer:
     

     
  • Special Symbols: From wilds to scatters, slots are packed with these symbols which, when showing up on the reels, trigger winnings and features. Wilds contribute to completing winning combinations, while scatters usually trigger bonus rounds and free spin sessions. Since they award players with extra credits in such various ways, it’s no wonder special symbols are so popular among the slot fans.
