Gems Infinity Reels Slot Review
Under a pale moon in a canyon of purple crystal spires, four gem-powered princesses fight cosmic evil, and Gems Infinity Reels is at its best when it makes you wait for them. This is a game that starts almost every spin on two small grids and pays out its biggest moments only to those who sit through the build-up. ReelPlay runs it on two stacked 3×4 reel sets that can grow into four, with a 96.3% RTP, medium-high volatility and a ceiling of 2,267x the bet.
It shares its engine with West Coast Cash Infinity Reels, and the studio’s catalogue nearby runs through Hercules 10K Ways and 10,000 Wonders MultiMax. Four gem-powered princesses give this one a Saturday-morning energy that suits it well. The real question is whether two grids are better than one.
Base Game & Features
You start on two reel sets, Ruby on top and Sapphire below, each a 3×4 grid that begins every spin with four reels. Everything the game does grows out of that pairing. The four sets are named for their gems, and two of them only ever arrive through the bonus:
- Ruby: topmost set, active in the base game
- Sapphire: second set, active in the base game
- Emerald: unlocked during free spins at 5 UNITY collected
- Spinel: unlocked during free spins at 15 UNITY collected
Wins need three or more participating symbols of a kind, paying left to right. From there, every win follows the same arithmetic:
- Participating symbol count multiplied by that symbol’s value
- Result multiplied by the base bet, which is the total bet divided by 25
- Coinciding wins for different symbols added together
- Wins on different reel sets added together
UNITY is the exception to nearly all of it. It pays anywhere rather than left to right, and it counts across every active reel set at once rather than staying inside its own. Where the two grids pay separately, UNITY is the one symbol that treats them as a single game.
Infinity Reels
The expansion rule is simple. If the rightmost reel of a set improves any symbol combination, a new reel is added to the right and spun. If that one improves things again, another follows. A UNITY symbol landing on the rightmost reel with no combination in play also extends the chain.
Wins are calculated only once no further reel is added. Each new reel also bumps the Symbol Multiplier by 1, and there’s no upper limit on how many reels can be added or how high that multiplier can climb. Every spin resets it to 1 across all active reel sets.
Wild Princesses
The Wild Princesses give the base game its second layer. Each wild substitutes for all symbols except UNITY and appears only on her own reel set. When she substitutes for a symbol of her matching type, the payout for that combination is doubled, once, no matter how many wilds are in it.
A wild princess covering all three rows also adds 1 to the Symbol Multiplier. Each princess is a type match for two symbols on her set, and she’s the only wild who doubles them:
- Wild Ruby Princess: Ruby set only; type match for Ruby Spear and Ruby Gem
- Wild Sapphire Princess: Sapphire set only; type match for Sapphire Necklace and Sapphire Gem
- Wild Emerald Princess: Emerald set only; type match for Emerald Quiver and Emerald Gem
- Wild Spinel Princess: Spinel set only; type match for Spinel Crown and Spinel Gem
The regular princess symbols, without the wild, only appear on reel sets that don’t currently have their matching Wild Princess. Participating symbol counts for wilds are calculated as the number of rows the symbol covers in the active three-row display, so a full-height wild counts as three participating symbols.
Gems Infinity Reels Free Spins & Unity Bonus
Any UNITY symbol win in the base game awards five free spins, played at the bet of the triggering spin. The round is built around collecting UNITY symbols as they appear, and each collection milestone does two things at once:
- 5 UNITY collected: five more free spins and the Emerald reel set unlocks
- 15 UNITY collected: five more free spins and the Spinel reel set unlocks
- All four sets unlocked: any UNITY symbol win adds three extra free free spins
The escalation is the point. You start the bonus on the same two grids as the base game, and by the end you can be playing four 3×4 sets at once. Emerald and Spinel stay in play until the round finishes, so the collection work is never undone mid-bonus.
All symbols are calculated within their own reel set, with two exceptions. Coinciding wins on different sets are added together, and UNITY counts across every active set. The four grids behave as parallel games that share one multiplier and one UNITY counter.
The Unity Bonus is the round’s headline prize. Land at least one of each Wild Princess type, each covering all three rows of her reel set, on a single free spin, and it pays 888x the total bet. The Symbol Multiplier doesn’t apply to it.
That last detail matters more than it looks. The whole game is built on a multiplier that grows with every added reel and every full-height wild, and the one prize you’d most want it applied to is the one prize it skips.
Our Honest Verdict
Overall Rating: 7.7/10
Playing this feels like watching the princesses gather their strength before the fight actually starts. Most of a session is quiet two-grid play, and the reason to pick it is the moment that changes: reels extending on both grids while the multiplier climbs with each one. When a chain gets going, it’s genuinely gripping.
The free spins round is the strongest thing here, because unlocking Emerald and Spinel means the bonus you finish is a different, bigger game than the one you entered. The Unity Bonus is the weakest: demanding all four full-height wilds on one spin for a prize the multiplier skips is a poor return for that much alignment, and it rarely feels like a realistic target.
This suits players who enjoy a long build and don’t need a jackpot chase to justify it. Chasers of instant bonus hits will find the pacing too slow. But anyone happy to let four grids and four princesses do their work will find the crystal canyon pays off patiently.
