Slot Providers

What a slot provider does

A provider, or studio, designs the game: the reels, the features and the maths behind the RTP. The casino licenses it and hosts it on its own site, and independent test labs certify that the random number generator works as it should. That is why the same Sweet Bonanza turns up at nearly every casino. Our library holds 111 studios and 2,877 free demos (November 2026), and the three largest, Pragmatic Play (878 games), Playtech (354) and Play'n GO (304), make up 53% of it. This page compares studios by size, mechanics and RTP; for the whole catalogue, go to the slots library.

The largest studios in our library

Eleven studios have their own page, ordered here by games in the library.

Pragmatic Play

Pragmatic Play has 878 games and, according to its own site, its headquarters in Gibraltar. It leans on cascading reels (83 slots) and Megaways (68). Its best-known game is Sweet Bonanza, released on 25 June 2019, which pays for 8 or more matching symbols anywhere on the screen.

Playtech

Playtech says it was founded in 1999, is listed on the London Stock Exchange and has 354 games. Our library tags 35 of them Cash Collect and 25 jackpot. Its Age of the Gods series has four jackpots in every game.

Play'n GO

Play'n GO has 304 games and is based in Vaxjo, Sweden, according to a 2023 interview. Its landmark is Book of Dead, released on 14 January 2016, with free spins where one symbol expands across the whole reel. Seven of its slots are cluster pays.

Blueprint Gaming

Blueprint Gaming was incorporated in Newark, England, in 2007 and has 143 games. Big Time Gaming licensed it Megaways in May 2018, and it now has 18 Megaways slots, such as Diamond Mine Megaways, and 33 jackpot slots. It is also the biggest Irish-themed studio here, with 20 games.

Hacksaw Gaming

Hacksaw Gaming was founded in 2018 and has 87 games, 36 of them dated 2026. It started with online scratchcards and listed on Nasdaq Stockholm in June 2025. Wanted Dead or a Wild introduced its DuelReels and pays up to 12,500x.

Red Tiger

Red Tiger, founded in 2014 and part of Evolution, has 62 games. It is the bonus buy studio: 45 of its slots, the most of any studio. Blood Suckers Megaways is a good example.

NetEnt

NetEnt has operated since 1996 and also belongs to Evolution. Of its 53 games, 24 have bonus buy, and 29 of the 51 with a volatility rating are labelled medium. Its calling card is Starburst, released on 23 January 2012.

Light & Wonder

Light & Wonder has 44 games, 18 of them Irish-themed. They are mostly Rainbow Riches slots, a brand from Barcrest, a studio that started near Manchester in 1968. See Rainbow Riches.

Big Time Gaming

Big Time Gaming began in Sydney in 2011 and has 30 games, 11 of them Megaways. It created the mechanic, and Extra Chilli is its best-known title in our library.

Nolimit City

Nolimit City was founded in 2014 and Evolution completed its purchase on 8 August 2022. It has 27 games, every one high or very high volatility, and 10 with bonus buy. Tombstone R.I.P. pays up to 300,000x according to the studio.

ELK Studios

ELK Studios is a small studio with 15 games, mostly its Cygnus and Pirots series. It holds a Malta B2B licence (issued 27 February 2019) and a UK Gambling Commission account, according to its site. Four of its slots have bonus buy, and Pirots 5 is dated 23 July 2026.

Studios by signature mechanic

A mechanic belongs to no single studio, but some use it far more than others. These are our library's counts in November 2026:

• Megaways: Big Time Gaming created it, with up to 117,649 ways to win per spin, and licenses it. Of 140 slots, 68 are Pragmatic Play, 18 Blueprint Gaming and 11 each Big Time Gaming and Red Tiger.
• Cash Collect: a symbol gathers the cash on the reels. Of 150 slots, 43 are Pragmatic Play, 35 Playtech and 17 Blueprint Gaming.
• Hold and Win: prize symbols lock while the reels respin. Of 111 slots, 35 are Pragmatic Play, 12 Red Tiger and 8 Big Time Gaming.
• Cluster pays: groups of matching symbols pay. Of 52 slots, 29 are Pragmatic Play and 7 Play'n GO.
• Bonus buy: you pay to enter the bonus. Of 167 slots, 45 are Red Tiger, 24 NetEnt, and 14 each Pragmatic Play and Big Time Gaming.

RTP and volatility by studio

Averages are for games with a published RTP. Big Time Gaming (96.40%), Pragmatic Play (96.38%) and NetEnt (96.29%) lead; ELK Studios (94.42%) and Blueprint Gaming (94.99%) trail. On 100 spins of 20 cent, a €20 stake, that is an expected return of about €19.28 at Pragmatic's average and €18.88 at ELK's: 40 cent apart, over a long run, and any single session can be far from either. Only 561 of Pragmatic's 878 games and 98 of Playtech's 354 have a published RTP, so those averages do not cover every title.

Which studios are available in Ireland

Each studio signs with casinos one by one, so no casino has everything. Of the 37 Irish casinos we review, 36 carry Pragmatic Play, 31 carry Evolution, 29 carry Play'n GO and 25 each carry Hacksaw Gaming, Playtech and NetEnt. Red Tiger is in 24, Nolimit City in 23, Blueprint Gaming in 21, Big Time Gaming in 19, ELK Studios in 14 and Light & Wonder in 10.

Irish searches follow the same order, with two surprises. In November 2026, "pragmatic play" got about 1,600 searches a month in Ireland, but "nolimit city" got 590 and "hacksaw gaming" 480, more than Playtech (140), NetEnt (70) or Play'n GO (50). "ELK Studios" got 210, though only 14 casinos carry it.

The lobbies we checked in early November 2026 agree. PlayOJO Ireland's Popular Games row had Pragmatic's Big Bass Bonanza and Gates of Olympus, along with Play'n GO's Book of Dead and NetEnt's Starburst. BetVictor Ireland and LeoVegas Ireland showed Book of Dead and Legacy of Dead, and LeoVegas had Pirots 5 from ELK Studios in its first row. We saw no Nolimit City game in the lobbies we looked at.

The Irish theme is a studio strength: Blueprint has 20 games, Light & Wonder 18, Pragmatic Play 13 and Playtech 10, from Rainbow Riches to Leprechaun's Luck. Start with our best slot sites in Ireland, or the NetEnt casinos.

Each demo here is the studio's own game for free play. Real money is different. The GRAI has licensed remote betting in Ireland since 1 July 2026 and online gaming licences are due from 2027, so check a casino on our safest online casinos list and compare our real-money casinos before you deposit. Gambling is for adults 18 and over. If it stops being fun, GamblingCare.ie runs a free helpline on 1800 936 725, and there is more on responsible gambling.
