Online Casino Slots – A 101

This article is primarily aimed at inexperienced online casino slots players although those of you who have already played online might still find something of interest. It basically goes into detail on the fairness of online casino slot games along with the expected returns (RTP) and explains how you know which online casinos have which slots.

The Casino Software

The first thing I should point out is that the majority of good, safe online casinos licence their software from one of 4 recognised and very reputable software providers: Playtech, Microgaming, Wagerworks (IGT) and Realtime Gaming. You will often see references online to “Microgaming casinos” or “Playtech slots” for example which is primarily because the suite of games supplied by each provider is available at many casinos.

You’ll probably be familiar with the name IGT and WMS if you frequent land based casinos and both of these slot manufacturers now create a number of games for licencing online. Names that spring to mind are “Zeus”, “Cleopatra”, “Treasures of Troy”, “Kitty Glitter” and “Wolf Run” among others. You can actually see a list of casinos and videos of many of IGT’s online slot games at the IGT Slots website.

My advice would always be to look for one of the logos of the 4 software providers above – or that of IGT or WMS – on the homepage of an online casino. If it’s not obvious, then either ask the casino’s support, or go somewhere else!

Game Fairness

The reason I started this article with an overview of software providers is because not all  online casino slots are fair but those that are present on those 4 platforms above are. Each has been TST tested (certification of fairness) which means the random number generators used are truly random. That means every spin of every slot is independent of the last.

As far as expected returns go then the norm for online casino slots is between 91% and 97% (or even a little higher on occasions). This is generally better than in land-based casinos and there are several contributary factors for that decision. Firstly, online casinos have fewer overheads than land casinos; secondly the games are available 24/7 and as a generalisation, online slot players will play more regularly; and thirdly many of the slot games have a higher variance (risk) attached. I won’t go into variance here but if you want to understand more about it – and it is VERY important to understand – then check out the slot variance article at Slotjunkies.

Where To Play Online Slots

All of the online casinos here at Online Casinos Slots use one of the software providers mentioned above and are good, safe casinos. I’ve played at them all myself at one time or another so I can vouch for that.
