ELK Studios Features

Slots Optimized for Mobile

Since its founding in 2013, ELK Studios has developed slots for mobile devices with graphics and sound on par with the desktop versions. The games are designed with smartphone screen sizes and even power consumption in mind.

A carefully designed user interface is another hallmark of ELK Studios slots.

A Wide Range of Themes, from Fantasy to Sci-Fi

ELK Studios slots cover a wide range of themes, including fantasy, science fiction and adventure. Many games put their characters front and center, while series such as Tahiti Gold and Ecuador Gold have a darker style.

Games such as Taco Brothers and Poltava stand out for their reel animations, and much of the lineup is built around original features.

Betting Strategies, a Rare Feature in Slots

ELK Studios slots come with built-in betting strategies, something rarely found in slots.

A betting strategy automatically adjusts your bet in the slot, following rules such as “raise the bet after 5 losing spins” or “adjust the bet based on a balance target you set.”

A betting strategy changes only how much you bet, and therefore how much your balance swings. It does not change the return to player (RTP) or the house edge. It is simply a way to automate raising and lowering your bet.

ELK Studios Licensing and Fairness

ELK Studios holds multiple licenses and is audited by an independent testing lab.

Based in Sweden, ELK Studios is licensed by the Malta Gaming Authority (MGA) and the UK Gambling Commission (UKGC).

To obtain a license, a company has to pass a review by the licensing authority, and it remains under that authority’s supervision after the license is granted. Holding a license does not in itself guarantee that a provider is trustworthy, however.

The MGA and the UKGC are both regarded as particularly strict in their licensing reviews and supervision.

Audited by an Independent Testing Lab

Beyond its licenses, ELK Studios is regularly audited by the independent testing lab GLI, which verifies that its RNG (random number generator) and payouts work as designed. Results are generated at random, and any tampering with the system would be detected.

Things to Keep in Mind About ELK Studios

Do Not Overuse X-iter

Most ELK Studios slots use a system called X-iter.

X-iter lets you buy free spins and other features directly by paying more than your regular bet. Free spins cost 100x your bet, and super free spins cost 500x. Buying a feature does not raise the RTP, and on some games the RTP is set lower than in the base game.

Because the price is high, results can vary widely from one purchase to the next. Before you buy, check how many purchases your balance can cover at that price so you can decide whether it is worth it.

Many Games Have Rules That Are Hard to Follow at First

ELK Studios games have somewhat more complex rules than slots from other providers. Many of them are hard to grasp without a step-by-step explanation, and players who start without reading the rules often finish their first session without really understanding how the game works.

Each game’s info screen lists its rules and features. If they are still unclear after reading, try a few spins in the base game and free spins in the free demo to see how the game plays.
