What to Look for in a Yggdrasil Gaming Casino
When choosing a casino specifically for Yggdrasil Gaming games, check that the full catalogue is available (not just selected titles), that RTP information is displayed in the game's information panel, and that the casino holds a reputable licence (MGA, UKGC, or Gibraltar). Demo play (free play) for Yggdrasil Gaming games should ideally be available without registration.
Licensing and Fairness
Yggdrasil Gaming games are tested by independent certification labs (eCOGRA, iTech Labs, GLI, or BMM) before distribution. Each title must pass RNG certification. The RTP figures published by Yggdrasil Gaming reflect the results of these certified tests. No Irish casino currently holds a GRAI gaming licence — casino licences are expected 2027–2028.
Playing Yggdrasil Gaming Games on Mobile
Yggdrasil Gaming develops all games in HTML5, ensuring compatibility across iOS and Android without additional downloads. Game loading speeds and graphical quality on mobile are equivalent to desktop. Some titles include portrait mode for one-handed play.

Yggdrasil Gaming is a Swedish MGA-licensed provider known for their BOOST mechanics (Gigablox, Splitz, YG Masters). They operate a game-publishing platform (YG Masters) allowing third-party studios to build games using Yggdrasil's tech — increasing catalogue size.
Yggdrasil Gigablox Mechanic: Explained
Gigablox is a Yggdrasil mechanic where large symbol blocks (2×2, 3×3 or even 4×4) land on the reels, covering multiple positions simultaneously. What it means in practice:
- All symbols in a Gigablox are identical — a 2×2 Gigablox fills 4 reel positions with the same symbol, dramatically increasing win frequency when it lands.
- Variance changes: Gigablox games are typically medium-high variance — the mechanic creates streaks (multiple Gigablox spins can be very profitable, then long dry spells).
- Splitz: Another Yggdrasil mechanic — symbols split into smaller copies during free spins, increasing ways to win dramatically. Used in games like Stacked.
GigaBlox is a Yggdrasil mechanic that generates oversized symbol blocks (2x2, 3x3, up to 6x6) on reels, paying as multiple individual symbols. It significantly affects winning potential on a given spin.
YG Masters is Yggdrasil's white-label development programme, allowing third-party studios to publish games using Yggdrasil's distribution platform and mechanics IP. It's similar to Relax Gaming's Silver Bullet model.
