Stone Wilds Under the Gorgon’s Gaze

Medusa’s Stone turns Greek-myth character symbols into stone wilds, then asks you to catch them early enough for the multiplier meter to matter.

Medusa’s Stone is a high volatility slot from Pragmatic Play with 96.46% RTP and 7,000x max win potential. The Medusa’s Stone slot uses a 5-reel staggered 3-4-4-4-3 layout with 20 fixed left-to-right paylines, stone wilds, free spins and super free spins. Swing-ready bonus hunters get the clearest value here, especially if they enjoy multiplier meters that build under pressure.

Key takeaways

Best bonus: Super Free Spins returned $437 from a $400 buy, while the standard buy returned $33.50 from a $150 buy. These are demo feature-buy test results, not a casino bonus or promotion, and no wagering requirement is implied.
RTP / volatility: Official RTP is 96.46%, volatility is high, and you’re dealing with real swing pressure.
Max win: The maximum win is 7,000x the bet, and the round ends if that cap hits.
Risk note: The strongest rounds need the free spins multiplier meter to build early, so you can’t rely on late wilds.
Bankroll note: My 500-spin test at $2 finished down $47, and you need a stake that survives quiet stretches.

Frequently Asked Questions About Medusa’s Stone
Final Thoughts

Theme & First Impressions

Medusa’s Stone uses a cracked Greek temple where the Gorgon’s gaze drives the whole mechanic. You see glowing eyes in the back wall, victim statues around the board, and a staggered reel shape that makes the middle columns feel dangerous.

Idle staggered reels show balance and buy sign — Watching the idle temple board settle.

Temple setting

The theme won’t win originality awards, but I think the execution works because the art serves the feature. The characters don’t just sit there as premium symbols. They can turn to stone, and that stone becomes wild.

If you like myth-heavy slot worlds, Journey to the West offers a brighter fantasy angle, while this game feels darker and more mechanic-led. You get a colder temple, sharper lighting, and a feature built around fear rather than adventure.

Did You Know? Medusa’s myth works well here because “turning to stone” becomes the wild-symbol mechanic, not just background art.

Reel layout

The board uses five reels in a 3-4-4-4-3 layout, with 20 fixed paylines reading left to right. This is a line slot, not a ways, cluster, or pay-anywhere game, so you can track wins without doing mental gymnastics.

The staggered board stays easy to read on desktop and mobile because the middle reels carry the main action. I like that choice. You always know where the danger sits, and the theme works because it ties directly into the gameplay idea.

How Medusa’s Stone Works

Medusa’s Stone pays through 20 fixed left-to-right paylines on a five-reel staggered grid. You don’t get a normal wild in the paytable. The only wild appears when a character symbol turns to stone.

Payline wins

I ran the whole test at a $2 bet, so the symbol values here match that stake. Only the highest win on each line pays, and wins on different lines add together. That keeps the math clear when several lines connect at once.

Line win resolves across helmet symbols — Banking the $2 helmet line.

The BONUS and SUPER BONUS heads sit outside the normal pay ladder. Both land only on reels 1, 3 and 5, so line wins, not scatter counts across every reel, drive the base game. I prefer this clarity because you can read a spin fast.

The screen layout works cleanly on mobile because the buy button, meter and reels stay visually separated. You don’t need to hunt around for the key information, even when the middle reels fill with stone wilds.

Quick Fact: There isn’t a normal wild in the paytable. Wilds only appear when character symbols are petrified.

Symbol values

At $2, the bearded king pays $50 for five, $10 for four, and $5 for three. The dark-haired hero pays $25, $7.50, and $2.50 across the same counts. Those two matter most when Medusa catches the centre reels.

The armoured warrior pays $20 for five, $5 for four, and $2.50 for three. The golden-haired priestess pays $10, $4, and $2. Below them, the sword and plumed helmet both pay $4 for five, $2 for four, and $1 for three.

A, K, and Q sit at the bottom and all pay $2 for five, $1 for four, and $0.50 for three. That low-card floor explains why many winning spins in my test still landed below the $2 stake. If multiplier-led line slots appeal to you, Hot To Burn Multiplier gives a useful comparison point, though this game leans harder on feature timing.

The base game depends on line wins first, then wild conversion. You’re not waiting for mystery math. You’re waiting for the right characters to stand in the right place when the Gorgon looks.

Stone wilds show six times and four times — Reading the stone wild multipliers.

Medusa Spin

Medusa Spin is the base-game feature that can turn character symbols on reels 2, 3 and 4 into wilds. It can fire on any base-game spin without warning, and I saw it often enough to keep the session moving.

Wild conversion

When the feature triggers, every character symbol on the middle three reels turns to stone. Those new wilds substitute for everything except the BONUS and SUPER BONUS heads. Card ranks, the sword, and the helmet don’t change.

That rule matters more than it first appears. You can see several middle-reel symbols and still get a poor result if most of them are low ranks or objects. I think that gives the feature a nice bite, because it looks generous but still demands the right setup.

Pro Tip: Don’t judge a Medusa Spin only by how many wilds appear. Low symbols are unaffected, so the middle reels need character symbols before the trigger matters.

Base-game impact

The middle three reels are the tallest part of the board, so a strong Medusa Spin can cover the centre with wilds. Bigger base-game hits need that centre to hold several character symbols before the feature fires. You feel the difference right away.

Across my 500 spins, Medusa Spins fired regularly and stopped the base game from feeling dead. They usually paid in the tens of dollars, not hundreds, at my $2 stake. That felt fair for session energy, but it didn’t replace the bonus rounds.

I’d treat Medusa Spin as personality rather than protection. It adds useful lift to ordinary spins, but the free spins rounds still carry the larger potential.

Free Spins

Three BONUS heads award 10 free spins, and the round uses a multiplier meter that can turn ordinary line wins into better results. You can’t retrigger the round, so those 10 spins have to do all the work.

Trigger rules

The BONUS heads only appear on reels 1, 3 and 5. When three land, the game moves into a special reel set. Inside that round, the Medusa Spin adds a stronger twist.

Rules page explains parked wild symbols — Checking how parked wilds behave.

Petrified wilds can carry 2x, 3x, 4x, 5x, or 6x multipliers. Any stone wild that misses a winning line stays parked on the board until a later win uses it. I like this because a dead-looking spin can still set up the next one.

Did You Know? A stone wild can still matter when it misses immediately, because it can stay parked until a later line win uses it.

Multiplier meter

Every used wild multiplier adds into the meter on the left. The whole collected total then multiplies every winning combination for the rest of the round. That means early collection matters far more than a late 6x wild with one spin left.

Parked wild remains with four spins left — Holding the wild with four spins left.

My 500-spin session produced three organic free spins rounds. The first two were modest, and the third paid $195, which was 97.5x my $2 bet. That hit saved the whole test from looking much rougher.

The round plays like a slow build. You want the early spins to bank multiplier, then you want the later spins to connect lines while that meter has weight. Standard free spins can pay well, but they need the meter to wake up early.

Collect screen shows thirty three dollars fifty — Banking the $33.50 collect.

Super Free Spins

Super Free Spins awards 12 spins with stronger wild multipliers and a higher Medusa Spin frequency. It isn’t just the standard round with two extra spins, and my buy test made that clear.

Higher multipliers

Three SUPER BONUS heads during a Medusa Spin trigger the super version. Red reels mark the upgrade, and the round still uses the same no-retrigger rule. The collection meter also works the same way.

Red reels show thirty four times collected — Reaching 34x before the last spins.

The real upgrade sits in the multiplier band. Stone wilds carry 4x, 5x, 6x, 7x, or 8x values, so the meter can become useful much sooner. I think that single change matters more than the extra spins.

Bonus-round chasers may also know Hot to Burn – 7 Deadly Free Spins, but this game’s super round feels more focused on meter growth than bonus variety. You’re chasing one idea here. Get the meter up early, then hope the lines keep connecting.

Test result

I bought Super Free Spins for $400 at my $2 stake. It returned $437 across 12 spins, clearing the purchase price by $37. That isn’t a huge profit, but the round showed the mechanic at its best.

Collect screen returns four hundred thirty seven dollars — Clearing the $400 buy price.

The first stone wilds already carried 6x and 8x values. The meter reached 10x within a couple of spins and climbed to 34x by the final spin. Then ordinary-looking line wins started paying much larger totals.

You can see why the super version feels more compelling. It doesn’t promise safety, but it gives the meter a better chance to matter before the round runs out.

Bonus Buy Test

The game has no ante bet, but it lets you buy standard Free Spins for 75x bet or Super Free Spins for 200x bet. At my $2 stake, that meant $150 for the standard round and $400 for the super round.

Buy prices

The purchase sign sits on the left column. When you open it, the screen shows a green banner for standard Free Spins and a red banner for Super Free Spins. After you choose one, a confirm panel appears with a red cross and a green tick.

Buy menu opens with two purchase prices — Opening the $150 and $400 choices.

The cost comes off the balance when you press the green tick. Then the round waits on a press-anywhere screen before starting. I like that extra confirmation, because these buys jump quickly from casual spin size to serious session risk.

The published RTP for the game is 96.46%. That figure doesn’t make the feature safe, though, because the result still depends on meter timing.

Caution: This is a high volatility slot. A $400 super buy can win, as it did in testing, but it can also miss badly if the meter doesn’t build early. These figures are demo feature-buy outcomes, not promotional bonus cash, so bonus terms or wagering requirements are not part of the test.

Bought results

My standard Free Spins buy cost $150 and returned $33.50 across 10 spins. The meter reached only 6x by the final spin. Wilds arrived, but they landed too late or failed to complete lines early.

That round showed the weak side of the mechanic. Parked wilds look promising, yet they need time and winning lines to convert into meter value. When the meter wakes up late, you don’t have enough spins left.

The super buy cost $400 and returned $437. The meter climbed to 34x, and ordinary line wins became much more meaningful because every later win used the collected total. In this tiny sample, Super Free Spins looked more compelling, but one buy of each doesn’t prove long-term value.

The buy feature increases pace, not safety. You’re paying to reach the volatile part faster, and you still need the round to build early.

RTP, Volatility & Our Test

The official RTP is 96.46%, volatility is high, and the maximum win is 7,000x the bet. The game uses 20 fixed left-to-right paylines, and any round that reaches the 7,000x cap ends immediately.

Simulator projection

Our 1,000-spin model used the 96.46% published RTP, high variance rating, and 7,000x ceiling. At a $2 bet, it put the median 1,000-spin result at $128.60 down. That number tells you the base-game grind can bite even when the headline RTP looks solid.

Modelled balance path tracks one thousand spins — Projecting the $128.60 median drop.

The middle 90% range ran from $635 down to $736 up. That wide band fits what I felt while testing, because one bonus round can reshape the whole session. You can be grinding downward, then one meter build changes the graph.

The model put paying spin frequency around 18%. It also estimated a feature-tier hit about once in 45 spins, with a 100x win or better about once in 1,700 spins. I wouldn’t treat those figures as comfort, because the big swing still comes from whether your free spins collect multipliers early.

Our 500-spin session

I started with a fresh $100,000 demo balance and played 500 spins at $2. I finished on $99,953, so I was down $47. On paper, that looks almost flat.

The path didn’t feel flat at all. The base game paid often enough to stay active, but many paying spins returned less than my $2 stake. My balance sagged into the low $99,700s before the late recovery arrived.

Session balance line dips before late recovery — Tracking the late pullback toward level.

Three free spins rounds triggered naturally. The first two stayed small, while the third paid $195, or 97.5x the bet. Without that hit, my session would’ve looked far colder.

Theoretical RTP is the operator’s published figure, and one live or demo session doesn’t change it. Feature-buy test results help explain feel, pacing, and mechanic behaviour, not your guaranteed return.

The numbers look solid, but the high volatility makes timing matter. You need the meter to build early, not merely appear.

Bankroll Feel From 500 Spins

The game felt swingy over time, even though my 500-spin result finished close to level. You get enough small wins to stay engaged, but the balance can still slide while you wait for a real meter build.

Session rhythm

Base play gave me frequent small line wins. Many of those wins paid below the $2 stake, which slowly dragged the balance down. Medusa Spins helped the grind feel less empty, but they rarely turned into massive base-game hits.

That rhythm creates a strange session feel. You see action, you get conversions, and you don’t feel ignored by the game. Still, the money can move the wrong way while the screen stays busy.

Hot to Burn Extreme makes sense as a comparison if you’re judging pure swing appetite, but this game hides some of its risk behind a busier base game. I think that can trick impatient players into raising stakes too early.

Bankroll notes

Use a stake that can survive base-game sag. The $195 free spins round covered most of my earlier damage, but it arrived late. You can’t assume your session gets the same rescue.

The buy feature also deserves care. The $150 and $400 prices at a $2 stake change the pace fast. If the meter doesn’t build, the result can look brutal.

Patient bankroll managers have the right temperament for this slot. Steady-grind players may get annoyed, because the biggest value sits behind bonus timing rather than constant base-game profit.

Frequently Asked Questions About Medusa’s Stone

What is the Medusa Spin in Medusa’s Stone?

The Medusa Spin is the base-game feature. It can fire on any spin, and when it does, every character symbol on reels 2, 3 and 4 turns to stone and becomes wild. Those wilds substitute for everything except the BONUS and SUPER BONUS heads, while card ranks, swords, and helmets stay unchanged. In my 500-spin run, it fired often enough to keep the base game lively, but most wins stayed in the tens of dollars.

How do Medusa’s Stone free spins actually pay?

Three BONUS heads award 10 free spins, and the round can’t retrigger. Stone wilds inside the round carry 2x to 6x multipliers, and unused wilds can stay parked until a later line win uses them. Every used multiplier adds to the meter, then that meter total multiplies later wins. You want early meter growth, because late wilds have less time to help.

Is the Super Free Spins purchase worth the extra money?

In my testing, yes, mainly because of the higher multiplier range. The standard $150 buy returned $33.50, while the $400 super buy returned $437. The super round reached 10x on the meter within a couple of spins and finished at 34x. That’s only one round each, so you shouldn’t treat it as proof, but the upgrade felt meaningful. These were demo feature-buy results, not casino bonus funds, so there is no promotional wagering requirement attached to those figures.

What did 500 spins on Medusa’s Stone return?

My 500-spin test started with a $100,000 demo balance at a $2 bet and ended at $99,953. That left me down $47. Three free spins rounds triggered naturally, and the best hit was a $195 round, worth 97.5x my bet. That one bonus covered most of the base-game damage.

What does the simulator say about a longer run?

The SatoshiHero Slot Simulator used 96.46% RTP, high volatility, and the 7,000x cap. At a $2 bet, it projected a median 1,000-spin result of $128.60 down, with the middle 90% range from $635 down to $736 up. It also modeled a 100x win or better about once in 1,700 spins. It can’t predict whether your own free spins meter builds early.

What are the RTP and maximum win in Medusa’s Stone?

Medusa’s Stone has 96.46% RTP, high volatility, and a maximum win of 7,000x the bet. Feature buys keep the same RTP truth used on this page. If a round reaches the 7,000x ceiling, the game pays the win and ends the round immediately. You lose any remaining features at that point.

Final Thoughts

Medusa’s Stone stands out because its stone-wild idea feeds directly into the multiplier meter. The main drawback is clear too: high volatility can make long stretches feel costly before one bonus pulls things back.

My Verdict

Bonus hunters with patient bankroll habits should try this one in demo first, then decide whether the swings feel comfortable. Expect active base play, modest Medusa Spin wins, and bonus rounds that depend heavily on early meter growth. I’d keep stakes sensible because the best moments arrive unevenly.

I like the way the super round showed the mechanic’s full strength. I don’t like how weak the standard buy felt when the meter reached only 6x by the end. My 500-spin session also proved that a near-flat result can hide plenty of pressure underneath.

Medusa’s Stone is playable on SatoshiHero in demo and real play, and this page is checked regularly against the playable version and rules screen. That matters here because small RTP and feature details shape the buying decision.

Pros:

Strong core idea: Stone wilds connect the theme and mechanics clearly.
Solid RTP: 96.46% gives the base game a fair published return.
Super round lift: Higher multipliers can make the meter matter quickly.
Readable layout: The staggered reels stay clear on desktop and mobile.

Cons:

High swing pressure: Quiet stretches can drain balance before bonuses help.
Weak standard buy risk: Late meter growth can sink the purchased round.
No retriggers: Free spins end fast if early wilds don’t connect.

Best For: Greek-myth fans, bonus-buy testers, and high-volatility players get the most from this slot’s pace. You’ll enjoy it more if you can wait through small base-game returns while chasing a strong multiplier meter. Steady-profit grinders should keep stakes low or stick to demo play first.
