A near-flawless crypto casino with tournaments, minus a few localisation gaps.
ELK Studios is a Swedish game studio that makes video slots for online casinos, from Wild Toro to the Pirots, Nitropolis and Cygnus series. Here you can see every ELK game with the studio's own RTP and top-win figures, try most of them free, and find casinos that carry them.
An ELK slot has the same features and rules wherever you find it, because ELK builds it and the casino only runs it. What the casino decides is everything around the game: how fast your winnings arrive, what you can deposit with, which bonuses you get and whether their terms are fair. For ELK’s newest games the casino also picks the RTP version, which can differ by market and operator.
Every casino here carries ELK Studios' games. A game's features and rules are the same wherever you find it, so this list ranks the casinos we rate highest on what the casino itself controls.

ELK Studios is a Stockholm game studio, founded in 2013 and owned since December 2021 by the American games company Light & Wonder. It makes video slots and nothing else, supplying them to licensed online casinos rather than taking bets from players itself. It holds a UK Gambling Commission licence as Elkab Studios AB (account 40844) and a Malta Gaming Authority B2B licence as ELK Studios Malta Ltd (MGA/B2B/605/2018), and it also lists licences in Romania and Greece and supplies the regulated Ontario market.
The figures below are ELK Studios’ own. RTP (return to player) is the share of all money staked that a game pays back over a very long run; maximum win is the most a single round can pay, as a multiple of your stake. Press Play on a game to try ELK Studios’ own free demo.
Check the RTP at your casino. The RTP shown is the one ELK Studios publishes. Where a studio offers a game in more than one RTP setting, the casino chooses which to run, and the figure that applies to you is in the game’s rules or information screen at your casino.
For most of its 2026 releases ELK publishes an RTP range, such as 87.0% to 96.0%, that depends on the market and the casino. The figure shown for those games is the top of the range.
No games match that search.
RTP and maximum win are ELK Studios' own figures, last checked on 30 September 2026. The RTP a casino runs can be lower; check the game's rules at your casino.
Play responsibly. These demos use play money only: no deposit, no cash-out, no prizes. The same games played for real money are real gambling, for adults only. If gambling has stopped being fun for you or someone you know, help is available.
Slots are all ELK makes, so 155 of the 155 games we list are slots. Its signature is X-iter, a menu of up to five game modes, each priced as a multiple of your bet, that jump straight into a feature or bonus round; every ELK slot since Bompers in 2021 has it, and since Pirots in 2023 many also use CollectR, where characters move around the grid collecting symbols. Its best-known games are Wild Toro, Game of the Year at the 2017 EGR Operator Awards, and Pirots 2, Slot of the Year at the 2024 Game Developer Awards. ELK works in series: Pirots, Nitropolis, Cygnus, Tropicool, Oxygen and Wild Toro all run to several instalments, and its Gold Series follows the explorer Kane through games such as Ecuador Gold, Katmandu Gold and Valhall Gold. Pirots 4 changed after launch, moving on to new worlds. ELK rates volatility from 1 to 10 and most of its slots sit at 7 or 8, with top wins of 10,000x or 25,000x the bet on most recent titles and 50,000x on games such as Cygnus 6 and Grizzly Stampede.
Winning symbols disappear and new ones drop into their place, so one spin can pay more than once.

See the 113 gamesELK Studios is licensed as a games supplier, not as your casino. Elkab Studios AB, the Stockholm company, holds UK Gambling Commission licences for gambling software and game hosting (account 40844), and the register lists no regulatory action against it. A separate company, ELK Studios Malta Limited, holds a Malta Gaming Authority B2B critical supply licence, and ELK also lists licences in Romania and Greece and supplies the regulated Ontario market. ELK has been owned by Light & Wonder since December 2021 and still holds these licences in its own companies’ names. None of that covers your account. Your money is held by the casino you deposit with, under that casino’s own licence, so check the casino, not the games.

ELK Studios was founded in Stockholm in 2013 and released its first slot, The Lab, in October 2014. Its breakout game, Wild Toro, followed in November 2016 and was named Game of the Year at the 2017 EGR Operator Awards. Light & Wonder, then called Scientific Games, bought ELK in December 2021; ELK still trades under its own name from Stockholm. Since March 2021 every ELK slot has X-iter, its menu of paid game modes, and since Pirots in 2023 many also use CollectR. ELK describes its approach as quality over quantity, and it launched 26 games in 2025.

No. ELK Studios is a game studio: it makes slots and supplies them to licensed online casinos, and you play its games at those casinos. Your account, deposits and withdrawals are handled by the casino, under the casino's own licence.

In Stockholm, Sweden, where it was founded in 2013. The UK Gambling Commission register gives its head office as Master Samuelsgatan 56, Stockholm. A separate company, ELK Studios Malta Ltd, based in Ta' Xbiex, holds its Malta licence.
Yes. Elkab Studios AB holds UK Gambling Commission licences for gambling software and game hosting (account 40844, the software licence in force since March 2015), and the register shows no regulatory action against it. ELK Studios Malta Ltd holds a Malta Gaming Authority B2B critical supply licence (MGA/B2B/605/2018). ELK also lists licences in Romania and Greece and supplies the regulated Ontario market. Your money is still only as safe as the casino you play at.
Wild Toro, the 2016 slot about a bull and a matador that was named Game of the Year at the 2017 EGR Operator Awards, and the Pirots series, whose second game won Slot of the Year at the 2024 Game Developer Awards. Its other long-running series include Nitropolis, Cygnus and Tropicool.
X-iter is ELK's own feature menu: up to five game modes, each priced as a multiple of your bet, that take you straight to a feature or bonus instead of waiting for it to trigger. In Pirots 5, for example, the modes run from a 3x bet with more than four times the chance to trigger the bonus, up to a 250x bet super bonus. Every ELK slot released since Bompers in March 2021 has X-iter.
Yes. ELK offers free demo play of its games on its own website, and most of the games listed on this page can be tried in that official demo without opening a casino account.
It varies by game and by casino. ELK's own game sheets give 96.0% to 96.4% for slots released up to 2020, mostly 95.0% for 2021 and 2022, and 94.0% for its 2023 to 2025 releases. Most 2026 releases list a range of 87.0% to 96.0% depending on the market and the operator, so the casino decides which version you get: check the game's rules screen before you play.
ELK rates each game's volatility from 1 to 10, and most of its slots are rated 7 or 8. The lowest-rated games we list, such as Ho Ho Tower and Birthday!, sit at 4 or 5, and the highest, such as Route 777, Tahiti Gold and Katmandu X, at 9.
50,000 times your bet. Several ELK slots, including Cygnus 6, Grizzly Stampede, Nitropolis 5 and Buffalo Toro, have a 50,000x maximum win in ELK's own game data, and most recent releases cap at 10,000x or 25,000x.
