Gems Infinity Reels

Gems Infinity Reels (Yggdrasil) Slot Review

This Yggdrasil-published edition of Gems Infinity Reels drops players into a mystical crystal cave, built around dual Infinity Reels sets that expand dynamically as wins land. It starts life as two separate 3-reel sets before growing outward, giving the game a distinctive dual-grid identity from the very first spin.

Theme and graphics

The visuals lean into a dreamy, glowing crystal cave aesthetic, all shimmering gems, ancient temple architecture and cosmic purple tones. Radiant crystal symbols sit alongside princess characters and cosmic elements, with reel expansions, Wild Princess transformations and sparkling Unity effects all animated to a high standard — an enchanting, serene take on the treasure-hunt fantasy genre.

How it plays

Wins are formed by landing matching symbols on adjacent reels starting from the left, and every new reel added through the Infinity Reels expansion increases the symbol multiplier by +1, with no stated upper limit. Wild Princess symbols span 1x3 on the grid, substitute for regular symbols, and apply a 2x multiplier of their own to any win they help create. Landing three or more Unity Symbols triggers the free spins feature, complete with reel set unlocks along the way.

RTP and what it means

Gems Infinity Reels returns a theoretical 96.26% to players, a solid figure that puts it well within competitive territory for the format.

Volatility, free spins and max win

This is a high-volatility release. Free spins award 5 rounds to start, with the symbol multiplier continuing to climb as reels expand throughout the feature. Additional Unity Symbols during the bonus unlock new reel sets and add five extra spins each, and unlocking all four reel sets triggers the Unity Bonus — an 888x prize awarded when all Princess Wilds land in full across the expanded grids, with multipliers and expansions still active. The overall maximum win sits at 2,267x the stake. Stakes run from 25c up to $/€100 per spin, and there's no bonus buy option on this release.

The Unity Bonus payoff

Chasing all four reel sets open is very much the long game here — it takes sustained scatter luck to unlock the full Unity Bonus, but the payoff of an 888x prize on top of an already-expanded, multiplier-boosted grid is exactly the kind of moment high-volatility players tune in for.

Verdict

Gems Infinity Reels' Yggdrasil edition delivers a genuinely mystical crystal-cave adventure, with its dual-grid expansion, growing multipliers and Unity Bonus giving it real depth for high-volatility fans. The escalating multiplier system in particular rewards patience during a strong free spins run. Take it for a spin in the free demo at johnessyslots to see the reel sets expand for yourself.
