Online Casinos that Offer the Largest Selection of Slots

Staff Writer Editorials 4,029

Online casinos are constantly evolving as the climate of what players look for changes.

This has seen a number of changes in the last five to six years in how casinos present themselves to prospective players and also in how they meet the demands of their current player roster.

One of the most widespread changes is the moving from standalone software casinos to those that offer slots from multiple software suppliers who house them under one roof per say. Those who have played with online casinos in the earlier years of their existence online remember the days when if you wanted to play Microgaming games but also felt the desire to play Playtech slots that it would require registering with several casinos in order to do so. That meant sharing information with multiple casinos, and for some that was something they preferred not to do.

However, with the inclusion of multi-software casinos, those players, old and new, were presented with the ability to access games from a large number of software companies as a result of back-end software that allows casinos to provide a greater variety of options.

So the question becomes, what is the difference between the two, and who are the biggest casinos that offer the largest selection of slots. As you read on, we will explain the difference and the advantage or disadvantage and how it impacts you as a slot player.

What is the Difference Between Multi-Software Casinos and Software Powered Casinos

There is a notable difference between those casinos that offer a single software casino versus those that offer a multi-platform casino. The main difference is slot selection, and it not being all powered by one software company such as Microgaming, NetEnt or Playtech.

Each casino has the choice as to which software suppliers they include, and most will partner with the main three; NetEnt, Microgaming and Playtech. However, with an ever increasing market growth, software suppliers such as Play’n Go, Red Tiger Gaming, Quickspin, Yggdrasil and others are in a constant state of competition to gain market share. The result of that has seen many casinos adding the game libraries from those casinos to increase their attractiveness to online slot players, who often demand the latest games and a constant stream of fresh slot content.

The problem, or should we say, less attractive side to single software casinos is they only can offer games from that one supplier.

They are limited to the number of new slots they can introduce at their casino as they are at the mercy of the software supplier and the rate to which they release new slot content. That impacts the quality of gaming to some extent for a slot player as it limits game selection but also the different slot features that will be included within those slots.

To combat this, single software casinos are adding different gaming categories to their casinos to become more attractive to those who play at the casino. This includes integrating additional gaming variants such as online poker, bingo, live casino games and sports betting, and thereby in effect, making the casino a one-stop gaming destination versus just a casino.

How Software Powered Casinos Work

Software powered casinos operate using single software and as such, only have the ability to provide gaming selection that the software company has produced. This will include a variety of slot games as well as others such as table games, video poker and a smaller selection of speciality games like keno.

While those casinos are more than capable of offering a strong casino filled with excellent game selections, the reality is, they are bound by the actions of the software company and their schedule relating to new game releases. Most single software casinos require downloading of software and will often include instant play versions as well. However, when it comes to those who prefer mobile gaming, the single software casino often will require mobile users to download an app, and subsequently download each game to their mobile device. This is time-consuming to some extent, but more importantly, it uses valuable space on your mobile device, which is not ideal for most people.

Additionally, all promotions that single software casinos offer tend to be offered only at the one casino. The expectation to this is larger casino operators who may run promotions across all platforms they operate, but often the case will be that promotions become typical and often lack creativity leaving your bonuses offers stagnant and lacking appeal.

How Multi-Software Casinos Work

Multi-software casinos use a back-end system that permits the adding of different software to the casino. Those casinos operating under these platforms are able to hand pick which games they wish to include from each software and in effect, create a unique gaming platform that other casinos may not offer. While many will feature a large number of the same games, often the case will be that some games may only be found at that particular casino due to special agreements with the software company.

What is also important to understand about multi-software casinos is that they operate as an instant play casino. There is not the need to download software, nor is there the need to download an app when wishing to access the casino via your smartphone or tablet. This is due to mobile users having the same freedom to access the games using a mobile browser in the same manner as those accessed via a desktop computer.

Another feature of the multi-platform casino is not only can the casinos themselves create special promotions, but the software companies also can generate special promotions to steer players towards specific games. That provides added value from a promotional standpoint, and you often will see multi-software casinos that are part of a large gaming company that combine their resources to release far more generous promotions that often can have a value that exceeds those seen with many of the single software casinos.

One last advantage is that most multi-software casinos will furthermore work towards providing a platform that not only offers slots, but a full line up of gaming variants, and that only add to their attractiveness and features.
