What is the extra reel below the main grid for?

It displays 5 of its own symbols on each spin, complementing or strengthening winning combinations on the main grid.

How do multipliers accumulate during Free Spins?

Each new multiplier is added to the previous ones, creating a single combined multiplier that applies to all subsequent wins in the round.

What does "Pays Anywhere" mean in Gemza?

Wins are calculated by the total number of matching symbols on the screen, regardless of paylines or their positions.

How many Free Spins does Gemza award?

The round starts with 15 Free Spins, with 5 more added whenever 3+ new Scatters land during the bonus.

How can you increase the chance of triggering Free Spins without buying them?

Activate Chance x2 — it slightly increases the bet but also increases the chance of triggering Free Spins.

Gemza (BGaming) Play Online Free, Review & Demo

The ancient Dwarven kingdom mined precious gems for centuries until it woke a fire-breathing dragon — Gemza from BGaming combines Bonanza-style mechanics with a separate extra reel beneath the main 5×5 grid.

Pays Anywhere mechanic, Very-high volatility, 97.17% RTP, Hit Rate 8.17, up to x5,000 max multiplier.

⚠️ Discrepancy in the bonus mechanic description

The written description mentions a separate "Bonus game" featuring "Keys Multipliers," triggered by unearthing 4 old chests full of diamonds. However, this mechanic doesn't appear anywhere in the source's detailed features list, which only describes the Multiplier symbol, Free Spins round, Extra reel, and standard Chance x2 / Buy Bonus. It's worth confirming with the source whether this feature actually exists before publishing this card.

How it works

Symbols pay anywhere on screen — the final payout is set by the total count of matching symbols once a spin ends. After every win, symbols clear and empty cells refill from above — the refilling sequence continues with no limit until winning combinations run out. Beneath the main 5×5 grid sits an extra reel that reveals 5 additional symbols on every spin, helping complete or boost winning combinations.

Bonus features

💡 Multiplier symbol

Both in the base game and during Free Spins, the multiplier symbol carries a random value from x2 to x500 and stays on screen until the refilling sequence ends, at which point every multiplier's value is summed and applied to the final win. During Free Spins, dropped multipliers accumulate and stack with every winning spin, forming a common multiplier that applies to every subsequent winning spin of the round.

💡 Free Spins round

4 or more Scatters landing anywhere on the reels trigger 15 Free Spins. New drops of 3 or more Scatters during the round add another 5 extra spins.

💡 Chance x2 and Buy Bonus

Chance x2 slightly raises your bet and boosts the odds of naturally triggering Free Spins — it's disabled while Buy Bonus is active. The Free Spins round can also be purchased directly at a price shown on the button, which adjusts automatically to your bet.

Volatility

Very-high volatility paired with a fairly high Hit Rate of 8.17 promises frequent base-game returns with the potential for rare big hits — a 97.17% RTP unfolds mostly through stacking multipliers during Free Spins, where individual symbols can carry values up to x500. The x5,000 stake ceiling (up to €250,000 listed max win) is reached by summing multiple multipliers within a single refill sequence.

Pros

Above-average 97.17% RTP
Fairly frequent base-game returns at an 8.17 Hit Rate, despite Very-high volatility
Multipliers up to x500 sum together within a single refill sequence
An extra reel beneath the main grid boosts the odds of combinations

Cons

The chest and Keys Multipliers feature mentioned in the text isn't confirmed in the detailed features list
The top multiplier values (up to x500) are rare within the overall range
Detailed per-symbol paytable figures aren't disclosed in the available materials

Who it suits

Player profile	Verdict	Why
Hunters of large wins	🟢 Great fit	Multiplier stacking up to x500 and the x5,000 ceiling give a real shot at a big hit
Players who value frequent base-game returns	🟢 Great fit	An 8.17 Hit Rate delivers fairly regular wins despite the high volatility
Players who want flexible bonus access	🟠 Likely a fit	Choice between Chance x2 and directly purchasing Free Spins via Buy Bonus
Players who want full transparency on stated features	🟡 Maybe	The text-mentioned chest bonus mechanic is worth confirming before playing for real money

⚡ Is Gemza worth playing?

Yes, if you like the idea of stacking multipliers during Free Spins — the extra reel beneath the main grid and multiplier values summing up to x500 make chasing the dwarves' treasure genuinely engaging, though it's worth confirming the text-mentioned chest bonus mechanic, which isn't detailed in the source, before playing for real money.
