Last updated: 12 October 2026
Every slot studio’s sales deck leads with a big number. The trouble is that the numbers don’t match. Spinomenal’s own website still says it has “more than 120” games, while the largest independent slot catalogue lists 786 Spinomenal slots. Pragmatic Play’s site talks about “over 500 games” in its in-house slot portfolio, and the same catalogue counts 889. If you’re an operator building a lobby, or an affiliate building provider pages, you need a figure you can actually compare.
This ranking counts the slots each of the biggest casino game developers has released, from one dated source, with the method spelled out so you can repeat it. Everything here comes from SlotCatalog’s provider catalogue, each studio’s own website, trade press and company announcements, and Trustpilot, and none paid to be included.
The short answer: Pragmatic Play is the biggest slot provider by game count in 2026, with 889 slots catalogued on 12 October 2026, one ahead of ABXplay (888) and ahead of KA Gaming (829) and Spinomenal (786). If you count every game type rather than slots only, KA Gaming is the largest at 1,013 catalogued games (1,037 on its own site). Counted by group, Evolution’s four slot brands (NetEnt, Red Tiger, Big Time Gaming and Nolimit City) add up to 882 slots, close to Pragmatic on its own.
The biggest slot providers in 2026 at a glance
Counts are from SlotCatalog’s provider pages, read on 12 October 2026. “Slots” adds the video slots and classic slots on each page; “All games” includes live, table, scratch, crash and other types. The provider’s own figure is what its website said on the same day, where it gave one.
| # | Provider | Slots catalogued | All games catalogued | Provider’s own figure | Group |
|---|---|---|---|---|---|
| 1 | Pragmatic Play | 889 | 984 | “over 500 games” (in-house slots) | None known; distributes Reel Kingdom |
| 2 | ABXplay | 888 | 933 | 1,000+ games | None known |
| 3 | KA Gaming | 829 | 1,013 | 1,037 games, 829 slots | None known |
| 4 | Spinomenal | 786 | 804 | “more than 120” games | None known |
| 5 | Playtech | 561 | 834 | Not stated on homepage | Playtech plc |
| 6 | CT Gaming | 506 | 510 | Not stated on homepage | CT Gaming (online arm CT Interactive) |
| 7 | Play’n GO | 494 | 525 | Not stated on homepage | None known |
| 8 | Blueprint Gaming | 445 | 464 | 450+ games | Merkur Group |
| 9 | Novomatic (Greentube) | 437 (Greentube: 419) | 470 (Greentube: 439) | Not stated on homepage | Novomatic |
| 10 | Games Global | 435 | 576 | 1,300+ exclusive titles (whole studio network) | None known |
| 11 | IGT | 412 | 460 | Not stated on homepage | Apollo funds, combined with Everi |
| 12 | Amusnet | 407 | 450 | Not stated on homepage | Amusnet (formerly EGT Interactive) |
| 13 | High 5 Games | 384 | 389 | Not stated on homepage | None known |
| 14 | Red Tiger | 383 | 394 | Not stated on homepage | Evolution |
The cut-off is 380 slots. Below it, the next brands are Slot Factory (359), Skywind (357) and MGA Games (336), so the list stops at the first clear gap rather than at a round number.
How this list was built
The ranking uses one source for every count, so the numbers are comparable even where they differ from a studio’s marketing.
- Source. SlotCatalog’s provider directory, which tracks 1,488 game providers, sorted by “Games Quantity” on 12 October 2026.
- Slots only. Each provider page splits the catalogue by game type. The ranking adds video slots and classic slots and leaves out live dealer, table, card, dice, scratch, crash and “other” games. That matters: Playtech has 834 catalogued games but only 561 slots, because 146 of its titles are live casino games.
- Brand level. Studios are ranked under the brand they release games as. Group totals are in a separate table below, because adding sister brands together changes the order.
- One overlap merged. Novomatic and Greentube (Novomatic’s digital division) are catalogued separately, and many titles appear under both. They are shown as one entry so the same games aren’t counted twice.
- Cross-check. Each studio’s homepage was opened the same day to record its own figure. Where the two match (KA Gaming’s 829 slots, Blueprint’s 450+ games), that’s noted; where they don’t, the gap is explained in the review.
- User feedback. Trustpilot profiles were checked for most studios, plus vendor sites and trade press for operator-side evidence. Trustpilot profiles that mixed in unrelated businesses were not used.
Nothing here is a hands-on test. Game count measures volume, not quality, revenue or how well titles perform in your lobby. For a ranking built on portfolio strength, market reach and adoption instead, see our comparison of the top slot game providers for operators.
Why game counts from studios and catalogues never match
When you ask a studio how many games it has, you get whichever figure flatters it. Four things explain most of the gaps in the table above.
- Old website copy. Spinomenal’s “more than 120” and Pragmatic’s “over 500” read like numbers written years ago and never updated. Both studios release new slots every month, so their own homepages understate them.
- Game types mixed together. KA Gaming’s 1,037 includes 124 fish shooter games, 47 arcade games, 26 table games and 11 crash games. Only 829 are slots. Studio totals rarely separate the two.
- Network totals sold as one brand. Games Global’s “1,300+ exclusive titles” covers its whole network of partner studios. Under the Games Global brand itself, 435 slots are catalogued.
- Versions and variants. Catalogues list a game once per release, so sequels, jackpot editions and “Megaways” or “1000” versions of the same game each count. High-volume studios release many of these, which pushes their totals up.
For you, the useful number is narrower still: how many of a studio’s games are certified in your jurisdiction and live through your aggregator. A studio with 800 slots may have far fewer approved in Ontario, the UK or a US state. Ask for that list by market before you compare.
The biggest slot providers by group
Several of the largest casino game developers sit inside groups or distribute partner studios. Counted that way, the ranking changes.
| Group | Slot brands included | Slots catalogued | Note |
|---|---|---|---|
| Pragmatic Play with Reel Kingdom | Pragmatic Play (889), Reel Kingdom (114) | 1,003 | Reel Kingdom is a partner studio whose games Pragmatic distributes |
| Evolution | Red Tiger (383), NetEnt (250), Nolimit City (149), Big Time Gaming (100) | 882 | Evolution’s own catalogue is almost all live casino |
| Novomatic | Novomatic (437), Greentube (419) | 437 to 856 | Heavy overlap between the two brands, so the true figure sits between the two |
| Games Global | Games Global brand (435) | 435 (1,300+ titles claimed across its network) | Partner studios are catalogued under their own names |
Evolution built its slot side by acquisition. Red Tiger was bought by NetEnt in September 2019 for £220 million and came to Evolution when it acquired NetEnt in 2020; Big Time Gaming followed in 2021 and Nolimit City in 2022, according to Gambling Insider’s timeline of Evolution’s deals. If you sign Evolution’s slot content through one contract, you are buying one of the largest slot catalogues in the market.
The 14 biggest slot providers reviewed
1. Pragmatic Play
- Slots catalogued: 889 (984 games in total, including 41 live casino games)
- Provider’s own figure: its homepage describes a slot portfolio of “over 500 games”, which trails the catalogue by almost 400
- Reach: its site says it is certified or licensed in over 30 jurisdictions and offers games in 33 languages, through a single API covering slots, live casino and more
- Best for: operators who want the largest single-brand slot library plus live casino and engagement tools from one integration
- What users say: Trustpilot rates Pragmatic 1.1 out of 5 from 1,204 reviews, about 95% of them one star. Almost all come from players disputing losses, RTP and bonus-buy results on titles such as Gates of Olympus and Big Bass. Pragmatic’s response is that it supplies licensed operators and does not handle player accounts or withdrawals. For you, that volume is a preview of the complaint tickets a hit-driven catalogue brings to your support team.
Pragmatic Play, founded in 2015 according to SlotCatalog, is the benchmark for release volume. Its homepage on the day of the check led with a “Mega Release” of Gates of Olympus 2500, a reminder that franchise sequels and variants add a lot to the count. Add Reel Kingdom’s 114 slots, which Pragmatic distributes, and the combined library passes 1,000.
2. ABXplay
- Slots catalogued: 888 (933 games in total)
- Provider’s own figure: “1000+ games” on its homepage
- Catalogue mix: almost entirely video slots, plus a few card, roulette, lottery, crash and keno-style games
- Best for: operators and aggregators that need a large volume of themed slots to fill category pages
- What customers say (from ABXplay’s site): the homepage points buyers to integrations through aggregators and platforms including Relum, GR8 Tech, EvenBet Gaming and LuckyStreak, rather than to operator testimonials.
ABXplay is the name on this list most operators won’t recognise, and it’s here purely on volume. SlotCatalog gives 2001 as its founding year. Its pitch is “balance”: games that “look good, run smooth” and are easy to integrate. Before you sign, ask which of its titles are certified in your market, because a large catalogue from a lesser-known studio is only useful if the approvals exist where you operate.
3. KA Gaming
- Slots catalogued: 829 (1,013 games in total, the largest all-game catalogue)
- Provider’s own figure: 1,037 games live, of which 829 slots, 124 fish shooters, 47 arcade, 26 table and 11 crash games, “all built in-house”
- Reach: its site says it is licensed and certified in 16 jurisdictions, with 3,000+ partners
- Best for: operators targeting Asian and emerging markets where fish shooter and arcade games sit next to slots
- What customers say (from KA Gaming’s site): KA claims 3,000+ partners worldwide and more than 5,000,000 daily sessions, and calls itself “the world’s largest casino game supplier”. The slot figure on its site matches the catalogue exactly.
KA Gaming, which SlotCatalog lists as founded in 2014 and based in Taiwan, is the clearest case of slots versus total games. It has the biggest catalogue of any studio if you count everything, and the third biggest if you count slots only. It is also the one studio on this list whose own published slot count matches the independent figure to the game.
4. Spinomenal
- Slots catalogued: 786 (804 games in total)
- Provider’s own figure: “more than 120” HTML5 slot, lottery and table games, with 2 to 3 new titles a month, a figure clearly out of date
- Licences listed on its site: UK Gambling Commission, Hellenic Gaming Commission (Greece), ONJN (Romania) and a Malta Gaming Authority recognition notice
- Best for: operators that want a deep library of quick-release themed slots, available through most major aggregators
- What users say: Trustpilot rates Spinomenal 2.1 out of 5 from 12 reviews, nearly all from players unhappy with bonus payouts; the one mid-rated review praises the art. Operator-side, its site lists aggregator clients including SoftSwiss, EveryMatrix, BETConstract and Slotegrator, and recent deals include Caesars’ New Jersey brands and Betsson Georgia (July 2025).
Spinomenal, founded in 2014 by Lior Shvartz and Omer Henya according to SlotCatalog, shows why you shouldn’t take a studio’s homepage number at face value. Its own site understates its catalogue more than sixfold. Ask for a current title list, filtered by your market, rather than relying on the website.
5. Playtech
- Slots catalogued: 561 (834 games in total, including 146 live casino games)
- Separate brand: Playtech Origins has its own entry with 192 games, not included in the 561
- Catalogue mix: the broadest of the big suppliers: slots, live casino, 41 card games, 35 roulette games and more
- Best for: operators who want slots, live casino and a full platform from one listed supplier
- What users say: Trustpilot rates Playtech 1.2 out of 5 from 179 reviews on an unclaimed profile. Complaints centre on live games (disconnections, cancelled bets) and claims of rigged RNG, plus changes to its iPoker network.
Playtech, founded in 1999 according to SlotCatalog, ranks fifth on slots but second on total games, which tells you what kind of supplier it is. If you’re comparing pure slot depth, use the 561 figure; if you’re comparing a full casino content deal, the 834 is the relevant one.
6. CT Gaming
- Slots catalogued: 506 (510 games in total)
- Background: a Bulgarian land-based cabinet maker, founded in 1999 according to SlotCatalog, whose online games are supplied by CT Interactive
- Online certification: CT Interactive received Malta Gaming Authority certification for 20 more games in August 2025 and is certified in more than 19 markets, according to iGaming Capital
- Best for: operators in Central and Eastern Europe and Latin America whose players know land-based fruit and classic-style slots
- What customers say (from CT Gaming’s site): CT Gaming cites more than 715 gaming locations worldwide, over 215 employees and subsidiaries in more than five countries.
CT Gaming’s catalogue is almost entirely slots (506 of 510). Its online catalogue draws on its land-based heritage (the homepage leads with cabinets running titles such as Diamond King), which suits markets with a retail slot culture better than a lobby built around high-volatility feature buys.
7. Play’n GO
- Slots catalogued: 494 (525 games in total)
- Background: founded in 1997 according to SlotCatalog, best known for Book of Dead and its Reactoonz and Legacy of Dead series
- Beyond online: its site now promotes land-based and social casino products alongside online slots
- Best for: operators in regulated European and North American markets who want a slot-focused studio with recognisable franchises
- What users say: Trustpilot rates Play’n GO 1.2 out of 5 from 167 reviews on an unclaimed profile, mostly from players reporting dead spins and disputing advertised max wins on titles like Tome of Madness.
Play’n GO builds few non-slot games (31 of its 525), so its 494 slots are close to its full catalogue. The homepage shows a mascot chat widget that couldn’t be hidden for the screenshot.
8. Blueprint Gaming
- Slots catalogued: 445 (464 games in total)
- Provider’s own figure: 450+ games, 2 million active users and 14 jurisdictions, according to the counters on its homepage
- Owner: a member of the Merkur Group
- Best for: UK-led operators who want branded slots and the Jackpot King network
- What users say: Trustpilot rates Blueprint 1.6 out of 5 from 22 reviews, all one star, mostly from UK players complaining about bonus frequency on branded games such as Game of Thrones.
Blueprint’s own count and the catalogue line up closely (450+ against 464), which makes it one of the easier studios to plan around. Its catalogue leans on licensed brands such as The Goonies and King Kong Cash, so check that the brand rights cover every market you serve.
9. Novomatic (Greentube)
- Slots catalogued: 437 under Novomatic (470 games in total); Greentube separately has 419 slots (439 games)
- Background: Novomatic, founded in 1980 according to SlotCatalog, is the Austrian land-based group; Greentube is its digital gaming and entertainment division
- Best for: operators in German-speaking and Central European markets whose players want classic Novomatic titles
- What customers say (from Greentube’s site): Greentube presents itself as Novomatic’s digital gaming division, with products and services for operators and a client area for partners.
Treat the two Novomatic entries as one supplier with overlapping catalogues. Classic titles appear under both brands, so adding 437 and 419 would overstate what you actually get. The Greentube homepage was loading a hero video when the screenshot was taken.
10. Games Global
- Slots catalogued: 435 under the Games Global brand (576 games in total)
- Provider’s own figure: “a portfolio of 1,300+ exclusive titles” across its studio network, plus progressive jackpots
- Background: SlotCatalog lists Games Global from 2022, when it took over Microgaming’s content business
- Best for: operators who want one contract for a large network of exclusive partner studios and the Mega Moolah jackpot
- What users say: Trustpilot rates Games Global 1.5 out of 5 from 45 reviews on an unclaimed profile, mostly players saying bonus rounds rarely trigger.
Games Global is the biggest gap between brand count and network count on this list. If you’re comparing what one integration gives you, the 1,300+ figure is the relevant one. If you’re comparing studios that build their own games, use the 435. The homepage’s age confirmation overlay was hidden for the screenshot, not clicked.
11. IGT
- Slots catalogued: 412 (460 games in total)
- Owner: funds managed by Apollo, which completed the purchase of IGT’s gaming and digital business and of Everi on 1 July 2025 and combined them as IGT, headquartered in Las Vegas
- Branding: IGT’s homepage now carries both the IGT and Everi brands
- Best for: US operators whose players expect land-based hits such as Wheel of Fortune and Cleopatra online
- What customers say (from IGT’s site): IGT positions itself as a supplier of games, hardware, systems and digital solutions, with separate offers for the US and Canada, Latin America and EMEA.
The Apollo deal, valued at about $6.3 billion, means the IGT you contract with today is a different company from the listed IGT of a few years ago. The lottery business that stayed with the old listed company now trades as Brightstar Lottery. Check contract counterparties and certifications after the change of ownership.
12. Amusnet
- Slots catalogued: 407 (450 games in total, including 12 live casino games)
- Background: the Sofia-based supplier formerly known as EGT Interactive, which announced the Amusnet name in March 2022
- Products: its site covers online casino, live casino, land-based, jackpots and promotional tools, and was promoting a new studio, TripleX, on the day of the check
- Best for: operators in Central and Eastern Europe and Latin America who want classic-style slots with jackpot mechanics
- What customers say (from Amusnet’s site): Amusnet markets itself as a “leading gaming provider” with online, live and land-based products under one brand.
Amusnet’s catalogue grew fast after the rebrand: the 2022 announcement put its online library at more than 160 games, against 407 slots catalogued today.
13. High 5 Games
- Slots catalogued: 384 (389 games in total)
- Background: a US slot developer whose copyright line dates back to 1995; its site lists online and land-based games
- Best for: US-facing operators who want slots with land-based recognition
- What customers say (operator evidence): trade press reports distribution deals with bet365 and DraftKings, and the homepage was promoting Green Machine Blitz on the day of the check.
High 5 Games is almost all slots (384 of 389), so its count is close to its full library. It also runs a casino platform and a game studio offer for operators, listed under “Our solutions” on its site.
14. Red Tiger
- Slots catalogued: 383 (394 games in total)
- Owner: Evolution, via its acquisition of NetEnt, which had bought Red Tiger in September 2019
- Best for: operators who want steady slot releases inside the Evolution content deal
- What users say: the Trustpilot profile under Red Tiger’s domain mixes reviews of an unrelated consumer electronics business with slot complaints, so it isn’t a reliable signal and isn’t used here.
Red Tiger is the largest of Evolution’s slot brands, ahead of NetEnt (250 slots). Its homepage is now a player-facing hub with live popularity charts, which tells you how Evolution markets the brand. On its own it’s 14th; as part of Evolution it belongs to one of the largest slot catalogues on the market.
Which slot provider should you pick?
A bigger catalogue helps only if it fits your market and your lobby. Use game count as a filter, then decide on fit.
| Your situation | Start with | Why |
|---|---|---|
| Launching a new casino and need a full lobby fast | Pragmatic Play, KA Gaming, Spinomenal | Largest single-brand slot libraries, widely available through aggregators |
| Asian or emerging markets | KA Gaming, ABXplay | Volume plus fish, arcade and crash formats |
| UK-led | Blueprint Gaming, Playtech, Games Global, Red Tiger | Branded content, jackpot networks and long UK track records |
| US regulated states | IGT, High 5 Games, Games Global | Land-based heritage and US distribution deals |
| Central and Eastern Europe or Latin America | Amusnet, CT Gaming, Novomatic | Classic and land-based style content |
| You want one contract for the most slots | Pragmatic Play (with Reel Kingdom) or Evolution’s slot brands | 1,003 and 882 slots catalogued respectively |
Most operators reach these casino game developers through an aggregator rather than one by one. Our guides on how a casino game aggregator works and the top aggregator platforms cover that route, and our casino software explainer shows where studios sit next to platforms.
Does the biggest game count mean the best slot provider?
No. Game count tells you how much a studio has released, not how much of it earns. Even with 900 titles from one supplier, your players only see a few dozen on the first screens of your lobby, so what matters is which titles perform for them. The biggest slot providers by count are also not the biggest gambling businesses by revenue; for that view, see the largest gambling companies in the world.
Where count does matter: filling category and theme pages, running tournaments across many titles, meeting a content minimum in a new market, and, for affiliates, deciding which provider pages have enough games to support their own content.
Red flags when a studio sells you on game count
- A total with no breakdown. If the deck says “1,000 games”, ask how many are slots, how many are live or table, and how many are variants of the same game.
- A network total presented as one studio. Ask which titles the supplier builds itself and which come from partner studios on separate terms.
- No list by market. Only games certified in your jurisdiction count. Ask for the approved list for each market you operate in.
- A homepage figure that is years old. If a supplier can’t give you a current number, its account management may be just as slow.
- Brand licences that don’t travel. Branded slots can be restricted by territory. Check before you build a promotion around one.
Next steps
Shortlist three or four studios from the table, ask each for its certified title list in your markets, and compare those numbers rather than the headline ones. You can browse studios side by side in the Game Studios and Slot Providers directory.
