Synot
SYNOT Games is the online-slots studio of SYNOT, a Czech gaming group that spent three decades making fruit machines and video lottery terminals before it ever put a game in a browser. That heritage shows. Its most-played online title is the Egyptian book slot Book of Secrets, and around it sits a long run of joker-and-fruit games that would look at home in a Central European gaming hall. This page covers the studio and the licensed casinos that carry its slots.

A “SYNOT casino” is not run by SYNOT. The studio builds the games and licenses them to operators; the casino you sign up with holds your account, takes your deposits and handles support. Use the list below to find a site that is licensed for your country and stocks the catalogue, then open the provider filter in the lobby to pull up the SYNOT titles.
A land-based group that moved online
SYNOT Group was founded in 1991 by the Czech entrepreneur Ivo Valenta and his family, and grew into one of the larger gaming businesses in Central and Eastern Europe. Its factories still make slot cabinets and video lottery terminals for arcades and betting shops across the region, which is the part of the story most provider profiles skip. The online arm, SYNOT Games, came much later, launching out of Bratislava in 2016 to turn that land-based catalogue into HTML5 slots, with further offices in the Czech Republic and Malta. It is a smaller studio than the household names, closer in size and background to fellow Czech developers such as Endorphina and Apollo Games, or the Bulgarian cabinet-maker turned supplier EGT, all of which reached online slots from the same land-based tradition.
The catalogue: fruit, jokers and Book of Secrets
The library runs to more than 150 HTML5 slots, with a new one arriving roughly every month. Two strands run through it. The first is the classic line, built on fruit symbols, sevens, bars and grinning jokers in games like Respin Joker, Fruit Awards and Fruity Gold 243, which carries the arcade feel straight over from the group’s cabinets and keeps the maths simple. The second is the modern adventure and mythology side, led by Book of Secrets, a five-reel, ten-line Egyptian slot with an expanding special symbol and a free-spins round that has become the studio’s calling card. Around those you get pirate, skull and treasure-hunt titles such as Corsair Queen and Skull Bonanza. The common features are respins, expanding wilds, free spins and gamble rounds rather than anything experimental; this is a studio that leans on Amatic-style classic play more than on the big-mechanic arms race. Because every game is HTML5, it runs in a mobile browser with no download.
No progressive jackpots
Worth knowing before you go looking: SYNOT does not build progressive jackpot slots. There is no network prize pot climbing across its games, so if the chase for a life-changing jackpot is the point of your session, this is the wrong catalogue. What you get instead are fixed top payouts inside each title, reached through the respin and free-spin features. It is a fair thing to know up front, and it fits a studio whose roots are in cabinet play, but it does set SYNOT apart from the providers that market a big progressive as their headline.
Where SYNOT is licensed
SYNOT Games holds a supplier licence from the UK Gambling Commission under account number 54398, which lets its games be supplied to British-licensed casinos, and a B2B critical-supply licence from the Malta Gaming Authority, reference MGA/CRP/598/2018, issued in January 2019. On top of that, its games are certified for a long list of regulated European markets, among them Sweden, Italy, Romania, Greece and Belgium. A supplier licence is not the same as an operator licence: it means the games have been tested and approved, but the casino you actually play at runs its own age and identity checks and its own responsible-gambling and anti-money-laundering controls under its own regulator. Which SYNOT titles you can reach, and at what RTP, depends on that operator’s licence, so confirm the site is licensed for your country before you deposit.
The 2025-26 push into Brazil
The clearest sign of where SYNOT is heading is Latin America. When Brazil’s regulated online market opened on 1 January 2025, SYNOT certified its portfolio for it, clearing more than 140 games for local operators, and moved fast on distribution: a supply deal with Novibet in February 2025 and a tie-up with EstrelaBet later in the year put its slots in front of Brazilian players almost as soon as the market went live. For a mid-sized studio, being certified and live in a market that size from day one is a real statement, and it draws on the same land-based-to-online experience the group has used across Europe for years.
How we weigh a supplier like SYNOT
When we assess a games provider we look past the marketing to the things that are checkable: the strength of its licences, how much of the catalogue it builds itself, how openly it handles RTP, and whether the games have a character of their own. SYNOT scores well on the first two. Its UKGC and MGA licences are top-tier, and it makes its own games rather than badge-engineering other studios’ work, so the fruit-and-joker style is the house’s own. The caveats are the ones already flagged: no progressive jackpots, and a catalogue that leans classic, so anyone chasing the newest Megaways-style mechanics will find it conservative. RTP is often configurable by the operator, which means the figure at one SYNOT casino can be lower than at another; the in-game information panel is the only place that shows the setting actually in force, so it is worth a look before you play.
Who owns SYNOT Games?
SYNOT Games is the online-slots arm of SYNOT Group, a Czech gaming business founded in 1991 by the entrepreneur Ivo Valenta and his family. The group has more than thirty years in land-based gaming across Central and Eastern Europe, making slot cabinets and video lottery terminals. The online studio launched separately out of Bratislava in 2016 to bring that catalogue into HTML5, with further offices in the Czech Republic and Malta.
Does SYNOT Games have progressive jackpots?
No. SYNOT does not build progressive jackpot slots, so there is no network prize pot climbing across its games. Its titles pay out through fixed top prizes reached inside the game's respin and free-spin features instead. If a big progressive jackpot is what you are after, this is not the catalogue for it.
Is SYNOT Games licensed in the UK?
Yes. SYNOT Games holds a UK Gambling Commission supplier licence under account number 54398, which lets its games be supplied to British-licensed casinos. It also holds a Malta Gaming Authority B2B critical-supply licence, reference MGA/CRP/598/2018, from January 2019. A supplier licence covers the games; whether you can play still depends on the casino itself holding a licence for your country.
What are SYNOT Games' most popular slots?
Its best-known title is Book of Secrets, a five-reel Egyptian book slot with an expanding special symbol and free spins. The classic side of the catalogue includes fruit-and-joker games such as Respin Joker, Fruit Awards and Fruity Gold 243, and the adventure themes run to titles like Corsair Queen and Skull Bonanza. The library runs to more than 150 HTML5 slots, with a new one arriving roughly every month.
Can you play SYNOT Games slots in Brazil?
Yes. When Brazil's regulated online market opened on 1 January 2025, SYNOT certified its portfolio for it and cleared more than 140 games for local operators. It signed a supply deal with Novibet in February 2025 and a tie-up with EstrelaBet later that year, so its slots have been available through licensed Brazilian sites since the market went live.
