Smaller Game Providers

In addition to the big developers mentioned above, there are many smaller, specialised casino game studios that release game less frequently. However these are usually games that have a lot of thought, creativity and effort put into them.

For example, Elk Studios has only 37 games listed in its portfolio. However, it has managed to win the Game of the Year award in 2017 and become the fourth fastest-growing tech company in Sweden in 2018. Another example is Thunderkick that has only 41 games in total, but a player base reaches far and wide around the world.

More up-and-coming game studios have an avid following of players. These are quickly getting noticed by developing superior games in straight competition with big game developers. Some names to watch are Gameburger, Switch, AII41, and Booming Games.

How We Rate and Review Game Providers on CasinoSource

There are tens of thousands of online casino games available to Irish players. So it difficult for a player to keep up with every game software company. This is where comes in to help. We have a large team of corporate and casino experts, mobile gaming experts, designers and mathematicians who work hard analyse every game provider and bring to you our conclusions.

We evaluate each game provider based on the following factors:

    👉 The number of games and types of games offered.

    👉 Player and expert reviews on reliability and quality.

    👉 Industry and technology awards won.

    👉 The number of monthly releases.

    👉 Mobile compatibilities and security features.

    👉 Licensing, compliance and regulations.

These are the main deciding factors of the ratings and reviews that an online casino software company receives from our team. However, we also make it a point to test each game and evaluate the interface, user-friendliness, gameplay, RTP, graphics and design, in-game features, and betting limits. The games of each software provider also count towards our ratings. You can also find detailed game reviews in our game section at

Top Progressive Jackpot Slot Developers

Progressive jackpot slots resemble the gameplay of standard slots. However, they feature a community prize pool. A software developer will contribute an initial amount of seed money to fund the jackpot prize. Then, a portion of each wager that every player makes will be allocated towards the prize pool. The prize will keep growing (i.e. progressing) until a lucky player will trigger the jackpot and win. The jackpot will then reset and start progressing again. Progressive slots give players a chance to win jackpots worth millions.

There are much less progressive slots than standard ones, as they can be quite challenging to develop and expensive to operate. However, the demand for progressive games has been increasing. The reason why progressive jackpot games are so sought after is that gamblers stand a chance to win an extra huge prize within a spin. This, apart from the bonuses and base game payouts.

Below are a few leading software developers that offer progressive jackpot slots:

  • NetEnt: Mega Fortune, Mega Fortune Dreams,Arabian Nights, Hall of Gods
  • Microgaming: Mega Moolah, Major Millions
  • Playtech: Jackpot Giant, Age Of The Gods
