Gemza Slot Overview
I took Gemza for a spin from BGaming, a 5x5 scatter pays slot set in a Dwarven Kingdom with a lurking dragon. Wins land when 8+ matching symbols hit anywhere, then the Refilling kicks in. There's an extra reel beneath the grid feeding five symbols per spin. Stakes run from 0.20 to 50, RTP is 97.17%, hit frequency 33.78%, and volatility is high. The top prize reaches 5000x, helped by Multiplier Symbols up to x500, Free Spins, Chance X2, and a Feature Buy.

Gemza Slot Information
The look places the reels in a dark cave, snow and rock framing the entrance, with controls tucked below and Chance X2 to the right. It plays well on mobile and desktop. Because of scatter pays, I only care about total matches per spin, not lines. Land any win of 8+ and the Refilling clears those icons so new ones drop. The extra reel under the 5x5 adds five symbols that can complete clusters and push fresh cascades.
Lower-paying symbols are black gem left, black gem right, black star, black crown, and black heart. With 12 or more of a kind, they pay between 2x and 10x. Mid hits of 8–11 pay less but cycle often thanks to the Refilling. Because wins count anywhere on the grid, those modest shapes can chain together nicely when the extra reel feeds the right pieces into view. I have seen long sequences built from these black stones when a small start keeps clearing.
Premiums are the green gem, pink gem, yellow gem, and blue gem, worth 12x to 50x for 12+. The Scatter is a golden key, paying 3x, 5x, or 100x for 4, 5, or 6, and it triggers Free Spins with 4+. The Multiplier Symbol is a wooden chest that can appear in base and bonus. There is no Wild here, so all momentum comes from refills, the extra reel, and those multipliers stacking at the right moment.

Gemza Slot Features
Refilling drives the base game in Gemza. Any win removes the matched symbols, then new ones fall, repeating until no more wins show. The extra reel beneath the grid is the twist I rate highly. It reveals five symbols each spin that can complete a cluster, extend a cascade, or sneak in a key. When the screen keeps clearing, you feel the pace lift, and the tally at the end can surprise on what started as a small connect.
Multiplier Symbols land with values from x2 to x500. In the base game, if several chests drop together, their values add before applying to the total. In Free Spins, all winning chests add to a running multiplier shown above the reels and that running value applies to later wins whenever a chest is present. Four or more keys award 15 spins, with 3+ keys adding 5 more. Chance X2 raises the feature odds for 25% extra bet, while Feature Buy costs 100x for 15 spins.
Gemza Details
A few numbers shape how I approach Gemza. RTP sits at 97.17% with high volatility, so I expect quieter patches broken by heavier sequences. The hit frequency of 33.78% keeps the base ticking, and the top win is 5000x. Bets range from 0.20 to 50. It is a pays-anywhere scatter slot with a 5x5 grid, refills, and an extra reel, playable across mobile and desktop. I toggle Chance X2 when chasing the bonus and drop it back for balance.
