Endorphina started building slots in 2012 in Prague. Their creative hub still sits in the Czech Republic, although the official corporate headquarters are found in Malta.

They got relatively popular over the years, and this can be explained by their approach to slot building. You see, Endorphina is the kind of software provider that's trying to make everyone happy, releasing both legacy and modern titles, most of them having a fixed RTP.

These days, to satisfy operator needs, they also ship a few slots with more RTP variations. To keep up with the intense competition, some of their modern slots, like Sloth Game, come with questionable or controversial themes.

Best Way to Pick Endorphina Casinos

If you want to pick proper casinos with Endorphina games, you need to find those compatible with said titles. There are hundreds of options in our list, and you should consider those with:

• Filterable game selection: While they've got 230 games in their selection, their identity isn't exactly clear. The slots can be what you'd expect to see on classic fruit machines, they can be modern, filled with features, or straight-up controversial.
• Mobile optimization: You can actually raise or lower the graphical quality of Endorphina slots, so it's easier on the phone and your data plan. This is great news, but not if the platform keeps stuttering and eats a lot of megabytes just to load up a page.
• Check the RTP version: You can easily see if a casino is generous or not by checking the RTP setting of some Endorphina slots within the paytable. For example, the Taboo slot ranges between 93.77% and 96.10%, so you could try verifying that one.

Which Endorphina Games Should You Know About?

You should know which game pays the most, the least, and which one has the highest potential. That's why 3 specific titles stand out amongst their otherwise mixed themes.

Rainbow Ray

I first started out Rainbow Ray without much expectation, since highly volatile slots tend to take their time with the payout. After 20 spins on a stake of $2, I got tired of waiting around, so I lowered the stake to $1 and bought a Bonus Pop worth $100.

It paid me x250, so I kept trying out the base game. It seems like paying often, but the sum was often x0.4 or x0.8 of my stake. I was trying to use the gamble feature without much success, so I just ended my session.

Taboo

Although Taboo will first stand out with its questionable theme, you'll then be more interested in the questionable RTP. You see, the game itself has a low RTP floor of 93.77% at casinos, which is way below the average.

This is the lowest setting I could find in Endorphina's selection. Although I'm not the biggest fan of the theme choice, I can give credit to the graphic quality of the symbols and how sleek the whole interface looks.

Royal Xmass

While Royal Xmass is a Christmas-themed game, you shouldn't forget about it in all the other 364 days. That's because this one has the highest maximum win of any Endorphina slot, sitting at a nice x93,750.

Sure, you probably need to land some near-impossible combination for it to actually pay out this sum, but it's good to know that there's a non-zero chance. My session wasn't that lucky, since 60 spins barely paid me anything, resulting in a x48 loss.

The Signature Gamble Feature of Endorphina Games

Endorphina didn't come up with the gamble feature idea, but they use a specific spin-off in most of their games. They call it the risk game, and it's pretty easy to understand. The dealer gets a card, which you can see, and you bet your winnings on one of 4 face-down cards.

It can either double your win if it's a higher number, or take it away if it's lower. According to Endorphina, the chance of winning depends on the dealer's card. A face-up 2 comes with a theoretical RTP of 162%, while a face-up ace will only give you an RTP of 42%.

Which RTP Setting Will I Play Endorphina Games On?

Most of the Endorphina slots at online casinos hover around the 96% RTP, and the majority also have a fixed RTP, regardless of the operator.

The catch is that some titles do ship with variable RTPs, and it's difficult to know which. Endorphina doesn't clearly state it. To find your setting, just go to the information tab within the game, scroll down to the very bottom, and you'll find the exact version set for your instance.

What to Remember Before Firing up Endorphina Casinos

You should remember that the demo mode will pay more than the real money version at Endorphina casinos. Some games can have different RTPs based on the operator, and the exact percentage can be found in the paytable.

Besides, even if you find good Endorphina bonuses, don't forget to do your background checks on the operator. Speaking of safety, most games from this provider let you set reality checks, so it goes without saying that you should play responsibly, within your means.
