Gemza Slot Overview
Gemza is a fantasy-themed slot from BGaming built on a 5x5 grid with a Pays Anywhere mechanic. You need 8 or more matching symbols landing anywhere on screen to form a win. Below the main grid sits an extra horizontal reel adding five more symbol positions per spin, which genuinely changes the dynamic compared to a standard cluster game.
RTP comes in at a very generous 97.17%, volatility is very high, and the max win caps at 5,000x. I loaded this up expecting another gem-themed Bonanza clone, and while the structure is familiar, the extra reel and the multiplier accumulation during Free Spins give it its own identity. Released December 2023, it runs smoothly on mobile and desktop.
Symbols and Paytable
Lower-paying symbols are black-shaded icons: gem left, gem right, star, crown, and heart. Landing 12 or more of any of these pays between 2x and 10x your stake. Higher-paying symbols are coloured gemstones: green, pink, yellow, and blue. Twelve or more of the blue gem pays the top regular prize of 50x.
Scatter is a golden key. Four keys trigger the bonus and pay 3x; five keys pay 5x; six pay a chunky 100x on top of launching Free Spins. The Multiplier Symbol looks like a wooden chest and carries a random value from x2 up to x500. There is no Wild symbol in this game, so all wins come purely from cluster matching and multipliers.
Symbol Payouts
Scatter
Landing 4+ anywhere triggers 15 Free Spins; payouts of 3x, 5x, or 100x for 4, 5, or 6 Scatters respectively.
Bonus Features Breakdown
The Refilling mechanic removes winning symbols after each payout, dropping new ones from above. Chains keep going until no new wins form. During refills in the base game, any Multiplier Symbols on screen stay put, and their values are summed together before applying to your total win for that spin sequence. That combination can produce surprisingly punchy base game hits.
Land 4 or more golden key Scatters and you get 15 Free Spins. Here is where it gets interesting for stream, chat. Every Multiplier Symbol that lands as part of a win adds its value to a cumulative Multiplier Meter above the reels. That meter carries forward and applies to all subsequent wins for the rest of the round. Three or more Scatters during the feature retrigger 5 extra spins.
Chance x2 costs 25% extra on your bet and doubles the chance of triggering Free Spins. Alternatively, the Buy Bonus lets you skip straight into the feature for 100x your stake. You cannot use both at once. If I'm honest with chat, the bonus buy price is reasonable, and the accumulating multiplier makes the feature round feel genuinely different from the base game.
Bonus Buy Options
Land 4 or more Scatter symbols anywhere to trigger 15 free spins. During free spins, all multiplier symbol values accumulate into a global multiplier applied to subsequent wins. Landing 3+ Scatters during the round awards 5 additional spins.

Volatility, RTP, and Max Win
97.17% RTP is well above average and one of the highest you will find from BGaming. Hit rate listed at 8.17% means roughly 1 in 12 spins produces a win, which feels low during sessions. Base game can drag a bit between clusters, so you really are leaning on refill chains and multiplier drops to keep things moving.
Max win of 5,000x is decent but not enormous for a very high volatility slot. Some viewers might expect more ceiling from a game this swingy. Still, the 97.17% RTP compensates, and the accumulating multiplier in Free Spins gives a realistic path toward bigger payouts if the round extends.
