What is SYNOT Games known for?
SYNOT Games is a Czech slot studio founded in 2016 within the SYNOT group, which dates back to 1991. It is known for fruit and book slots such as Book of Secrets, dice versions of its games and wide RTP ranges. It holds a Malta Gaming Authority licence, a UK Gambling Commission licence and several national licences across Europe.
The SYNOT name is much older than its online slots. Trade press marked the group’s 25th anniversary in 2016, putting its start in 1991 with three employees, and described it as a leading name in the Czech street gaming market with business in 20 countries. Today the group says it employs around 3,500 people in more than 40 countries.
SYNOT Games itself is young. Its own timeline starts in 2016 with a team of ten and a first game live, adds a Malta company in 2018 and reaches 250 employees by 2024. SlotCatalog gives 1997 as the founding year instead, so sources disagree, and we go with the company’s own dates. The studio has two bases: SYNOT Games Limited in Birkirkara, Malta, and the Czech companies in Uherské Hradiště, plus an office in Bratislava.
The land based background still shows. The studio supplies online and land based operators alike, and it played a part in OPAP’s rollout of 25,000 video lottery terminals in Greece. If many SYNOT slots feel like they came out of an arcade cabinet, that is no accident.
Most of the catalogue is fruit games, themed slots and dice variations, many of them with few lines and a gamble button. SlotCatalog counts 224 games, all but one of them video slots, and three older titles show the range well.
The 2018 take on the classic book formula: 5 reels, 10 lines, a book that works as both wild and scatter, and 10 free spins in which one random symbol becomes a special expanding symbol. SlotCatalog rates it high volatility with a top win of 6,227x the stake, and after a win you can guess the colour of a hidden card to double it.
Also from 2018, and laid out differently: a 4×4 grid paying 256 ways, with stacked wilds, free spins and the same double up option. SlotCatalog cannot agree with itself on the RTP, listing 93% in one place and 96.06% in another, so this is one to check in game.
A 2017 slot with no free spins at all. It pays both ways on 10 lines, and mystery symbols turn into a matching pay symbol once the reels stop. Low to medium volatility makes it a calm pick for a small budget.
Here is the part most players never see. Several SYNOT slots come in more than one RTP version, and the casino decides which one you get. These are SlotCatalog’s figures for the five games on this page:
| Slot | Released | Layout | Default RTP | Range listed |
|---|---|---|---|---|
| Book of Secrets | 2018 | 5×3, 10 lines | 96.05% | 85.15% to 97.94% |
| Alchemists Gold | 2017 | 5×3, 10 lines both ways | 95.73% | 88% to 97.97% |
| Mirror Shield | 2018 | 5×3, 10 lines | 95.63% | Range noted, values not shown |
| Hunters Spirit | 2017 | 5×3, 20 lines | 93.15% | Range noted, values not shown |
| Vampire Bride | 2018 | 4×4, 256 ways | 93% or 96.06% | Sources conflict |
Read the Book of Secrets row again. At the top of its range it returns close to 98%, at the bottom about 85%, and the game looks identical either way. Over a long session that gap decides whether a slot feels generous or simply drains your balance, and two SYNOT Games casinos can run the same slot at different settings. The only reliable check is the help screen inside the game at the casino you actually use.
For a mid sized studio, the paperwork is impressive. SYNOT says it holds 9 licences and 25 certifications, and its website lists the main ones.
In all, the games are certified in 26 countries, from Germany and the Netherlands to Colombia and Brazil, and the licence numbers are listed on the SYNOT Games website. In other words, this is a studio built for regulated markets, and the SYNOT Games casinos worth your time are licensed too.
The newer work goes in three directions. The first is dice. When the studio entered Belgium in December 2021, it released its first dice collection alongside reworked slots, with titles such as 81 Dice Awards, Respin Joker Dice and Book of Secrets Dice, and SlotCatalog still lists dice games like Voodoo Mystery Dice and Respin Joker 1000 Dice.
The second is bigger mechanics. The first SYNOT Megaways slot arrived in 2023, and SlotCatalog lists Tiki Princess Megaways for November 2026 with hold and win, a buy feature and a top win of 25,000x. The third goes the other way: in 2026 the studio launched Sixtronic, a new brand it bills as “seriously old school classic slots”.
Behind the games sit the operator tools. PEAK bundles tournaments, prize drops, challenges and a reward wheel, and SYNOT says its four level progressive bonus is integrated with all its slots. Whether you see any of it depends on the casino, so judge SYNOT Games casinos by what their lobby actually shows.
The list at the top of this page shows the open casinos in our database that carry SYNOT Games, with closed and blacklisted brands left out. SYNOT says its games are integrated on 38 platforms, aggregators such as Slotegrator among them, so the studio reaches very different casinos and the selection varies from lobby to lobby.
Before you deposit, check that the casino is licensed in the country where you live, and read the withdrawal terms, limits and processing times included. Given those RTP ranges, look up the return of the games you want in their help screens, and if you take a bonus, check that SYNOT slots count fully towards wagering. If you like the arcade style, the Prague studio Apollo Games is a close relative in spirit, and our full list of game providers covers the rest.
In the Czech Republic, where SYNOT Games CZ and SYNOT W are registered in Uherské Hradiště. The studio also has a Malta company, SYNOT Games Limited in Birkirkara, and an office in Bratislava.
Yes. It holds a Malta Gaming Authority B2B licence from 2019 and a UK Gambling Commission licence from 2020, plus licences in Belgium, Romania, Sweden, Denmark and Greece. SYNOT Games casinos should still hold their own licence for your country.
The studio’s own timeline starts in 2016, while the SYNOT group behind it dates back to 1991. SlotCatalog gives 1997, so the answer depends on whether you count the group or the online studio.
It varies by game and often by casino. Book of Secrets, for example, has a default of 96.05% but a listed range from 85.15% to 97.94%. Check the help screen of the game at your casino for the version you are playing.
Dice versions of its slots. SYNOT released its first dice collection when it entered Belgium in December 2021, with titles such as 81 Dice Awards, Respin Joker Dice and Book of Secrets Dice.
The studio reported 250 live games in 2026, and SlotCatalog counts 224, almost all of them video slots. The studio keeps releasing new titles, so the shelf in SYNOT Games casinos keeps growing.
