The company behind the online casinos

Responsible for the online slot machines are a lot of large and well-known casino providers from the Mediterranean island of Malta. It was already founded in 1980 and is the most popular provider of all for many fans of slot machines. Many players have played a slot machine for the first time in the gaming halls of The Company and fell in love with classics like Book of Ra there. So it's no surprise that Book of Ra is considered the most popular online slot worldwide apart from jackpot slots. By the way, we recommend the ICE Casino Bonus Code.

In the meantime, the company operates internationally and is represented with arcades all over Europe. It is also expanding into Asia and Latin America and is active in 90 countries.

The company has set itself the goal of continuing to be a trendsetter in the gaming market in research and the development of gaming equipment. With around 23,000 employees and a turnover of around 3.8 billion euros, it is one of the largest gaming companies in the world.

The software company, which is now fully owned by the group, is responsible for the implementation of slot machines for online casinos after specialising in offering solutions for casinos.

What has changed for online casino players in 2023?

With the departure of the popular gaming provider from the German market, we have decided to take a closer look at other online casinos. We specialise not only in classic casinos, but also in modern online casinos. After all, there are great alternatives on the market with Netent, Microgaming and Yggdrasil.

Other brands have also made strong inroads into the market. Very popular not only in England: Vera&John and ARES Casino.

Our casino providers where you can also play for free

It took a comparatively long time to offer the first online slots. In the meantime, there are several online casinos that make it possible to play the popular slots. The first provider of slot machines on the internet is Online Casinos.

It was able to establish itself as the first online casino and is today considered the largest and most successful online casino. It has even been listed on the stock exchange since 2002. In contrast to many other casinos, it is characterised by a more comprehensive range of games, including live casino. Of course, the casinos we tested also offer the possibility to play casino online for free.

In the meantime, however, this has received strong competition from other providers. Casinos like OVO Casino or Quasar Gaming try to win over customers through various unique selling points. These can be better bonus offers, a wider game selection or a more comprehensive customer service.

It seems that the casinos are subject to comparatively strict regulations. For example, not all online casinos accept players from all countries.

Best Online Casino Bonus

Good online casinos do not classically offer a no deposit bonus. The competition among the providers is relatively large and it can be assumed that the bonus programme of the casinos must be approved. Bonuses without deposit or free spins are almost never granted.

However, all casinos offer a new customer bonus that varies significantly in amount. The industry leader, for example, does not even advertise the new customer bonus, but only informs about it when the deposit is made. Then it also surprises with interesting turnover conditions that are unique in the industry.

The most popular online casino games

Most fans of slot machines appreciate slots for their game principle, which can provide hours of fun. Most slots have several paylines and provide more variety through scatter and bonus symbols. Bonus rounds and free spins make it possible to multiply the actual winnings.
