Online Casino Slots Information and FAQ


Ever since the first mechanical slot machines appeared towards the end of the 19th century they have been an integral part of casino experience, although the initial machines were first used in tobacco stores and bars. In the 1960s, Bally developed the first electromechanical slot and released it under the name of Money Honey. The honours to launch the first video slot fell to the Nevada-based Fortune Coin Co. who in 1976 graced the casino world with a monstrous-looking cabinet holding a 19” screen.

Fast forward to the 21st century and reports indicate that roughly 70% of casino revenue is coming from video slots. Hence, it comes as no surprise that we have today 200+ software providers and game studios vying to be at the top of the pile.

Online slots made their debut nearly a century after their mechanical ancestor. While it was a slow procession at first, the numbers are growing today at neck-break speed with the total surpassing 10,000 titles in 2016. 


Most of the online casinos listed below will feature anything from 500 to 3,000+ slot games on their sites.

Online Casino Slots: General Information


Online casinos pride themselves to offer slots and games for any taste and budget. A regular casino site will have 1,000+ titles in its portfolio, while some exceed 3,000. The play rules might look similar for most slots, but they do differ on layouts, bet sizes, number of reels and lines as well as bonus features.

In order to enjoy spinning slot reels online, you will need a suitable desktop PC, laptop, tablet or mobile device with a good internet connection. While the games are played in a browser or app, they still download a small temporary file with the graphics, sounds and features. A slow connection will lead to lagging games or interruptions which will end most probably in frustration instead of big win celebrations. In any other case, you are only a few clicks away to access the glittering world of online gambling adventures where a small bet can turn into a huge jackpot win.


Best Online Slot Providers (Developers)


Did you know that there are over 240 slots developers and game studios currently active just for online slots? And that number does not include the subcontractors and freelancers that contribute as well to the creation of a slot machine. Hence, picking the best out is something like finding the needle in a haystack. However, we do have statistical data and our own experience, which lets us judge who is at the top of the players’ favourites list:


  • NetEnt

  • Microgaming

  • Play’n GO

  • Blueprint Gaming

  • Elk Studios

  • Push Gaming

  • Big Time Gaming

  • Red Tiger Gaming

  • Thunderkick

  • Quickspin

  • Yggdrasil

  • Scientific Games


Best Online Casino Slots


Naming the best slots provider looks like an easy thing compared to naming the top online slots. The total number surpassed 10,000 titles in 2016, which makes picking out the top slots even more difficult as the variety is huge. You have different layouts, feature-rich or bare, low, medium or high volatility, awesome graphics or stuck in the 20th century and many more factors. However, looking at long-term statistics we can safely name the following as some of the most played slots in online casinos now:


  • Book of Dead from Play’n GO

  • Starburst from NetEnt

  • Dead or Alive from NetEnt (or try Dead or Alive II)

  • Bonanza from Big Time Gaming

  •  Jammin’ Jars from Push Gaming

  • Immortal Romance by Microgaming

  • Raging Rhino from WMS

  • Napoleon from Blueprint Gaming


New Online Slots for December 2019


There is hardly a day going by without an announcement for new online slots, each claiming to be the one with the most sophisticated graphics, best bonus features and biggest win potential. The well-known reels with fruits, bars and sevens have long been replaced with a vast array of characters and plots from comics, computer games, TV series, music, movies, fairy tales and many other equally exciting and vivid themes. Admittedly and probably for nostalgic reasons, there is still a sizeable number of classic slot machines available.

Modern "one-armed bandits" offer developers virtually unlimited possibilities for design, graphics, animations, sounds and game features. In addition, new online slot games offer a higher RTP (average return to player) than land-based casino slots. While slot machines run in the 80+ per cent range in B&M casinos, their online counterparts offer RTPs around 95 – 97%.

The stream of new online slots hardly ever slows down except for the duration of the summer months as many studios are based in Europe and specifically in Scandinavia, Malta and the UK where July and August are traditional holiday periods. We prowl daily the world wide web and our sources at game providers to bring you an updated list of new and upcoming online slots for December 2019:

  • 1 Left Alive | 4ThePlayer 

  • Wings of Riches | NetEnt 

  • Stumpy McDoodles | Microgaming  

  • Jewel Scarabs | Red Tiger Gaming

  • Book of Santa | Endorphina

  • Joker Troupe | Push Gaming 

  • Butterfly Lovers | Wazdan  

  • Divine Showdown | Play’n GO 

  • Aldo's Journey | Yggdrasil Gaming 

  • Sword of Khans | Thunderkick

  • Polar Paws | Quickspin 


Try Free Slots  No Download and No Registration


For novices and experienced players, it is advisable to try slots for free in so-called demo mode which you can do without any download or registration. All you need to do is pick a slot you like on sites such as Slotsmillion or Casumo and start playing with fun money. This will allow you to familiarize yourself with the rules, pay tables and mechanics plus getting a feeling on how the game performs. Remember though, all wins are not real money. Should you wish to play slots for real money, you will need to go through a simple registration procedure at an online casino and make a deposit. Online casinos accept payments with a large variety of methods such as bank transfer, debit/credit cards, e-wallets, prepaid cards, cryptocurrency and others.
