Online casinos succeed or fail partly on the strength of the games they provide. Because of this, they need to offer a great selection of exciting games to encourage their customers to keep playing with them.
Most casinos don’t make their own games, although Tombola is a rare exception. Most have partnerships with game providers, who create slots and table games, bingo, lotto, and live casino games.
You can find out more about how online casino software works here.
In this article, we’ll look at some of the best providers of casino software and a selection of their most popular games.
Whether you’re a recreational gambler or do profitable casino offers, having some insight into the best casino software providers can enrich your time playing online slots and games.
Types of Casino Games
Online casinos host a range of different types of games. These originated from versions in land-based casinos, bingo halls or other physical format like lotteries.
Here’s a list of some types of games you’ll find in online casinos:
There are hundreds of online casino game providers, with 654 currently listed by Slotcatalog.
To compile the list of some of the best providers, a combination of personal experience of doing hundreds of casino offers was used, alongside these internet sources:
Slotcatalog is a website that lists and reviews online casino games. It provides useful statistics like Return To Player (RTP), variance, maximum win, game features, and slot theme.
To make their SlotRank list of the most popular slots, Slotcatalog checks over 2000 online casinos worldwide daily. They look at the main ‘lobby’ part of the casino, using incognito mode to avoid any personalised recommendations affecting the results.
Slots in more prominent positions in the lobby are scored most highly. A weight multiplier is applied with more popular casinos in the country having a higher multiplier. The slots are then listed in score order to give them a popularity ranking.
The SlotRank will change daily, so the rankings below are just a snapshot of the list at the time of writing (13th February 2025) rather than a definitive list of the greatest slots. However, it gives insight into the current popularity of slots.
You can find more information about SlotRank at this link:
Slotcatalog uses the information gathered by SlotRank to compile a list of the highest-ranking Game Providers. Game providers are granted points according to how many games they have listed on SlotRank and their rankings on the list.
Here are the top 25 game providers in the ProviderRank list as of 13th February 2025:

International Gaming Awards Winners
We all know that industry awards aren’t perfect (there have been plenty of contentious winners and omissions over the years in awards ranging from the Oscars and BAFTAs to the GRAMMYs and Brit Awards, for example).
However, looking at casino gaming awards is a good way to gauge the importance and influence of game studios over time. With this in mind, we’ve listed historic winners of key awards most relevant to game providers.

The chosen categories are:

Games Studio of the Year
Some of these categories have been renamed, and those in the second table were introduced later. Companies with an asterisk next to them are involved in online casino software but aren't game providers.
