Felix Gaming is the studio behind It’s a Joker, a small 3 by 3 fruit slot with a clown on the reels that keeps turning up in the lobbies of Felix Gaming casinos years after its 2018 release. The rest of the catalogue is less famous, and that is half the fun of digging through it.
This page lists the open casinos in our database that carry Felix Gaming, and explains who runs the studio, what its slots are like, how they are licensed and what to check before you play.

What is Felix Gaming best known for?
Felix Gaming is a slot studio founded by land based casino veterans and owned by Bilyan Balinov. It is best known for It's a Joker, which the studio calls its top performer, along with fruit, Egyptian and book themed slots, Hold and Win titles and its own features such as Hyper Jump. Its games reach casinos mainly through Alea and the SOFTSWISS Game Aggregator.
Start with It’s a Joker, because Felix does. Felix Gaming calls it its top performer and says it has been a regular in the top 10 at several online casinos. On paper it looks modest: 3 reels, 3 rows, 5 lines and a clown for a wild.
The twist sits beside the grid. Side reels hand out free spins and multipliers from x1 up to x25, and a bonus clown can land in the centre position. SlotCatalog lists the game at 96.98% RTP with medium to high volatility and a top win of 700 times the bet, so think steady evening rather than lottery ticket.
Behind the Joker you find the themes Felix keeps coming back to: fruit, ancient Egypt, magic, books and the odd dragon. Book of Anunnaki, Lines of Magic, Pharaoh’s Temple and Red Lion all come from the same studio, and none of them try to reinvent the slot. They are built for players who like classic slots and want to know what they are sitting down to.
Felix Gaming was built by people who spent years around casino floors before any online casinos got one of their slots.
The owner is Bilyan Balinov, a name you will also see written Balinoff. He founded the studio with Chedomir Tomich, and SiGMA puts the pair’s experience in slot machine development at more than 25 years. Balinov has said the team studied what players search for and kept seeing words like “Book” and “Joker”. Look at the catalogue and you can see the research paid off.
On dates, sources disagree. SlotCatalog and an older SOFTSWISS profile say 2016, while the studio and a 2023 press release point to 2017. In early 2026 Felix brought in Georgi Donchev as COO and said it was growing in Bulgaria and working on certificates for several other European countries.
Felix likes to give its features names, and a few are worth recognising when you scroll a lobby.
You will find it in Juicy Wilds, a 20 line fruit slot. SlotCatalog files Hyper Jump under features that skip spins without a win. Fewer empty spins feel great, but a faster game also gets through a balance faster, so keep half an eye on the clock.
Balinov has named Line Booster as one of the studio’s real successes. Around it sits a family of titles such as 20 Boost Hot, 40 Hold Hot, Wolf Gone Wild Hold and Win and Book of Knight Hold and Win, classic themes with the studio’s own mechanics bolted on.
In February 2026 Felix Gaming said it was developing Felix Stars, a progressive jackpot system linked to its games that casinos can adapt to their own setup. The Felix site already mentions Felix Stars versions, so expect to see the name more often.
This is where Felix is harder to pin down than most of the studios we cover.
Felix’s own website lists two licensing bodies, the Malta Gaming Authority and Anjouan Licensing Services, but gives no licence numbers, and we could not confirm an MGA licence in Felix’s name for this page. An older SOFTSWISS profile described the studio as licensed in Curaçao with an MGA licence still to come, so the picture has shifted over the years.
Distribution is clearer. Felix names Alea as its exclusive direct integrator, and Felix Gaming titles also reach casinos through the SOFTSWISS Game Aggregator. Soft2Bet added the catalogue through AleaPlay in December 2020, and the REEVO aggregation platform took it on in October 2023. When the supplier side is this hazy, the licence that counts for you is the one held by the casino you play at.
Felix Gaming slots do not share one payout figure. These are the RTPs SlotCatalog lists for six of them, and the gap from top to bottom is close to four and a half percentage points:
| Slot | Layout | RTP at SlotCatalog | Volatility |
|---|---|---|---|
| It’s a Joker | 3×3, 5 lines | 96.98% | Medium to high |
| Pharaoh’s Temple | 5×3, 20 lines | 96.67% | Low to medium |
| Lines of Magic | 5×3, 20 lines | 95.92% | Low to medium |
| Red Lion | 5×3, 20 lines | 95.60% | Medium |
| Juicy Wilds | 5×3, 20 lines | 95.58% | Medium to high |
| Wild Beast of Crete | 5×3, 243 ways | 92.50% | High |
The studio’s own site quotes 96.5% for Book of Anunnaki, 95.8% for 40 Hold Hot and 94.9% for Jester’s Fortune. Felix Gaming casinos can also run a different version from the one in a database, so the number on the game’s info screen is the one to trust.
The list at the top of this page shows every open casino in our database that offers Felix Gaming. Closed and blacklisted casinos are not on it.
