ELK Studios is one of the few studios in the sector that deliberately refused to diversify.
Founded in 2014 in Sweden, ELK has kept an exclusive focus on video slots for a decade. It does not produce live casino, it does not run a B2B platform, it does not compete on volume. The strategy: produce a few premium slots with high-end 3D production and innovative mechanics. The result: the Wild Toro slot won the Slot Game of the Year award at the 2017 EGR Operators Awards.
In 2021 ELK launched X-iter, a system that lets the player choose between five game modes at the start of each session — guaranteed multipliers, direct bonus entry, free spins with fixed features. The mechanic has become a standard in its later releases.
Across our panel of 24 casinos, 3 offer ELK Studios — exclusively in Spain, where high-budget boutique slots find an audience.

X-iter: the System That Changed Game-Mode Selection
The X-iter system, launched in 2021, lets the player choose five different modes at the start of the slot:
- Standard mode — normal base game
- Guaranteed-feature spins — costs extra but free spins are always active
- Scaled multiplier — the bonus multiplier increases every spin
- Direct bonus entry — equivalent to a classic Bonus Buy
- Custom mode — variable depending on the slot
The trade-off is transparent: each mode has a multiplier price over the base bet. The player chooses how much risk to take on. X-iter has replaced the classic Bonus Buy in ELK releases since 2021.
Wild Toro: the Award-Winning Franchise
Wild Toro (2017) won Slot Game of the Year at the EGR Operators Awards — the most prestigious award in the sector. The franchise continues across three installments:
| Slot | Year | RTP | Max Win |
|---|---|---|---|
| Wild Toro | 2017 | 96.4% | 2,250x |
| Wild Toro 2 | 2020 | 96.3% | 25,000x |
| Wild Toro 3 | 2025 | 96.1% | 25,000x |
Wild Toro 3 expands the original mechanic. The grid is 5 reels x 4 rows, starting with 178 lines that can expand up to 421 during special features. The "Spanish homecoming" theme — bull, matador, plaza — works particularly well in Spanish-speaking markets, where bullfighting culture is a cultural reference.
Other Notable Slots
| Slot | RTP | Feature |

| Hidden Sanctum | 96.1% | Asian temple, X-iter active |
| Sam on the Beach | 96.3% | Summer, sticky wilds |
| Champions of Mithrune | 96.1% | Fantasy, multipliers |

Casinos With ELK Studios in LATAM/ES
We verified availability in May 2026:
Spain (3 casinos):
- Codere Spain — Wild Toro 3 + X-iter selection
- 888casino Spain — Wild Toro 2 + Hidden Sanctum
- LeoVegas Spain — broad ELK catalog
Argentina: sporadic availability via Bplay. Mexico: no significant presence in the panel.
ELK Studios concentrates its distribution in regulated European markets. The LATAM presence is limited by commercial strategy — the company bets on high-engagement players from mature markets.
Licenses and Operation
ELK Studios operates under UKGC and MGA licenses. iTech Labs audits its RNG and RTP. As a boutique, ELK keeps full creative control over each release, with no white-label content and no YGS Masters partners.
How We Tested ELK Studios
Three sessions between March and May 2026.
We opened an account at Codere Spain. We played 60 spins of Wild Toro 3 at a €0.50 bet — we triggered the free spins once with the Matador system, confirmed the expansion to 421 lines visually, and had a modest €34 win.
We tested the X-iter system on Valkyrie with 30 "scaled multiplier" selections at 888casino Spain. We confirmed that the multiplier increased 1x per spin and that the price (5x the base bet) matched the one declared.
We contacted LeoVegas support with the question "Is Wild Toro 3 available with X-iter in your catalog?". A reply came in 3 minutes 35 seconds, confirming the 5 active modes.
We cross-checked figures with BigWinBoard (Wild Toro 3 review), iGamingX, the EGR Operators Awards archive (2017 winner), and the UKGC and MGA registers.
We received no compensation from ELK Studios or the operators listed.
The Good and the Bad
The good
- Slot Game of the Year EGR 2017 — Wild Toro recognized by the most prestigious award in the sector
- X-iter unique system — choice of 5 game modes before starting
- Premium 3D production — cinematic-level graphics and audio
- Mobile-first design — the slots perform identically well on mobile and desktop
The bad
- Very small catalog — 40+ slots vs 200+ from competitors
- No significant LATAM presence — an explicit European strategy
- X-iter modes carry a high price — the direct Bonus Buy mode costs 100x+ the base bet
- High volatility — ELK slots are not for beginners; sessions can run long without reward
