Olympus Storm Slot Review – Greek Gods and Thunderous Features

Olympus Storm, specially chosen to be part of PokerStars Casino’s The Slotlist, invites players to climb the marble steps to a storm-lit mountaintop to face off against some of the most powerful gods in Greek mythology.

This online slot goes all in with its mythological theme, with features that match its epic tone. Gold Coin Studios has designed Olympus Storm around a familiar 5×3, 25-line layout, then turns up the voltage with several layered mechanics. Connectify Pays drives the Free Spins feature, three Power Combo features can combine into the X-Treme mode, and permanent Storm Levels slowly grow and build momentum during the session.

Theme & Design: A Slot Charged by the Gods

The aesthetics of Olympus Storm lean into Greek mythology, with marble columns bracketing the reels while Zeus’ heavenly kingdom of Mount Olympus sits in the background. While sessions begin more relaxed, as the features trigger, lightning will strike to add symbols, create connecting electric surges across lines, and leave the reels glowing with Zeus’ raw energy.

The soundtrack is epic and cinematic, with horns, drums and crashing cymbals fitting of a meeting with the Greek gods. Things start out calm at first, but when the Storm Levels start building with the bonus features, the music becomes more dramatic, with sound effects intensifying when the symbols land.

Main Features: Enter the Eye of the Storm

Olympus Storm runs on a 5×3 grid with 25 fixed paylines. Wins pay left to right, starting from reel one, and only the highest win on each line counts. The total payout for a win depends on the value of all the line wins. Wilds substitute for regular pay symbols, but never for the Wheel, Zeus, Artemis, Hades, Prize, or Collect symbols. Their role is simple: fill in gaps, extend lines, and try to improve the reel potential by using the mechanics built into the slot.

Below the reels sits the Storm Levels progress bar. Each time a Prize symbol lands without forming a win, the bar inches forward, creating a steady sense of momentum even when the reels are quiet. Reaching a new level triggers a new upgrade that sticks around for the entire session.

Storm Level Rewards

Storm Levels are the core of Olympus Storm. Each level unlocks new bonus features that stick around for the rest of the session. At Storm Level 1, Zeus Lightning triggers, with bolts striking the reels at random, with a chance of adding Wilds or Prize Symbols. While subtle, it does make the game feel more alive, and the sudden flash of lightning can transform a near-miss into a new win or a setup for Express Collect.

Storm Level 2 expands the base game even further with Wheel Symbols. Every Wheel that lands increases the Mega jackpot by +1x the bet and also carries the chance to trigger the Jackpot Wheel Bonus. From this point, each spin has a lot more potential, with a single symbol able to unlock a wheel feature that wasn’t possible before. At Storm Level 3, a new Free Spins Wheel symbol appears on reel five during Free Spins. When collected through Connectify Pays, it gives the player a spin on the Free Spins Wheel, with potential outcomes ranging from extra spins and cash values to jackpot prizes.

Finally, Storm Level 4, known as Olympus, introduces the Collect Symbol on reel one. This completes the Express Collect circuit, allowing the feature to trigger from both ends of the grid. When Collect lands on both reel one and reel five in the same spin, all visible Prize Symbols on the reels are paid out twice.

Together, these four levels reshape how Olympus Storm plays out. The early stages of the game stay calm and straightforward; the mid-game slowly introduces new mechanics; and late-session spins feel evolved and momentous. Each added mechanic adjusts the flow of the slot.

Express Collect

If a Collect icon shows up on reel five, it pays out all Prize Symbols on reels one through four. Once Storm Level 4 is unlocked, Collect can also appear on reel one, adding another entry point for landing winning combos.

When Collect lands on both sides in the same spin, every Prize Symbol on the reels pays twice. It’s quick, triggers sleek animations, and is self-explanatory thanks to how the layout of the interface and values are displayed. This includes the Prize Symbols, which typically range between 1x and 200x the total bet. Zeus Lightning adds more opportunities; if a bolt strikes and adds a Prize Symbol during a spin, that new symbol instantly becomes part of the next collection opportunity. When Express Collect triggers, Prize Symbols pulse on the screen, a counter combines the total, and any potential win finally pays out with a flash of lightning.

Connectify Pays

Connectify Pays sits right at the middle of Olympus Storm’s Free Spins, with the storm raging on, and lightning bolts becoming part of the game mechanics. The core rule is pretty straightforward: when lightning bolts land side by side across a single row, they create a charged path leading to reel five. If four lightning symbols connect across reels one to four in that row, the symbol on reel five for that line is instantly paid out. It’s a modern twist compared to older or classic slot games. Instead of expanding reels or collapsing clusters, Olympus Storm has the player track symbols horizontally instead, charging the path to line it to reel five, and collect whatever’s waiting there.

Since the entire mechanic revolves around rows, the best upgrades are the ones that can change the connection routes. That’s where the Power Combo trio comes in. X-Large extends the grid vertically by adding more rows, creating extra potential lanes for lightning to spread. X-Array expands connections outward, introducing a second direction that links to reel five. This extra path can sometimes lead to double collects in a single spin when the layout aligns just right. X-Spins, however, extends the round itself, giving extra Free Spins when collected symbols appear during play.

Where the design of Olympus Storm really shows how clever it is is when all of these systems overlap. Multiple Power Combo symbols can trigger together, meaning a Free Spins round can start with several features already active. When all three combine at once, it becomes the X-Treme Power Combo, which can turn the gameplay dramatic, including the base spin if the Triple Power Combo symbol lands.

Power Combos – Zeus, Artemis, and Hades

Each deity in Olympus Storm brings its own Power Combo to the table, and each one shifts how the Free Spins play out.

Zeus – X-Large

Zeus is the X-Large combo, which expands the grid. When his feature triggers, Free Spins begin with eight spins, played across a six-row grid, with three of those rows locked at the start. When an X-Large symbol appears on reel five and connects with the Connectify Pays system, one of the locked rows opens on the next spin. It’s a simple setup that literally gives the lightning more room to strike.

Artemis – X-Array

Artemis carries the X-Array feature, and she can also change the layout of the board. Her Free Spins round also starts with eight spins, but the reels stretch horizontally to add four new columns beyond reel five. Lightning can strike these reels, creating extra connection routes that make it possible to collect a reel-five symbol twice in a single spin when two separate paths appear.

Hades – X-Spins

The ruler of the underworld, Hades, has the X-Spins feature, focusing on extending the session rather than increasing grid size. Again, the round starts with eight Free Spins, but the goal is to get the X-Spins symbol on reel five. When triggered through Connectify Pays, it adds extra spins, which can be one, two, or three at a time. The pacing slows right down, and each added spin offers more chances for the lightning to connect across the grid.

Combining Power Combos

When two or more Power Combos activate together, their effects stack together. For example, when X-Large and X-Array trigger at once, the grid expands to six rows by nine columns. Landing the Triple Power Combo symbol is what offers the chance of Olympus Storm’s most powerful feature, the X-Treme Power Combo. It opens with eight Free Spins, and every other system is already active. The Bronze and Silver rows from X-Large start unlocked, meaning the feature begins with progress already made instead of building slowly.

Wheels and Jackpots: Letting Fate Decide

Olympus Storm divides its wheel systems clearly between base play and Free Spins, both of which are linked to Storm Levels. Once Storm Level 2 activates, Wheel Symbols can show up on any reel during the base game. Each one increases the Mega Jackpot and may trigger the Jackpot Wheel Bonus. The Jackpot Wheel offers five fixed tiers: Mini (5x), Maxi (10x), Minor (50x), Major (200x), and Mega (ranging between 1,000x and 5,000x). Should a Mega prize be won through the base-game wheel, it resets to its minimum value, allowing players to build it back up again across future spins.

Free Spins and Jackpot Jumbo Spins

During Free Spins, two more wheels can appear on reel five. The Free Spins Wheel symbol, which is activated at Storm Level 3, can be collected through the Connectify Pays system to award a spin on the Free Spins Wheel. This has a chance of giving extra spins (ranging from +1 to +3), cash prizes of 1x, 2x, or 4x the bet, or one of the jackpots. The Random Jackpot symbol on reel five triggers the Jackpot Jumbo Spin, a single-reel spin that can pay out one of the five jackpot tiers, with the Mega Jackpot worth 5,000x the bet during Free Spins. Both wheel systems fit nicely into the progression-focused design of Olympus Storm, especially the layering mechanics that don’t disappear after a couple of spins.

Other Gold Coin Studios Titles on PokerStars

Gold Coin Studios has created a reputation for taking classic reel setups and upgrading them with layered features and strong themes. Alongside Olympus Storm, two contrasting online slots, a haunted-house caper and a comical pirate hunt, show how large the studio’s range is.

Ghost Money Manor

Set inside a spooky manor, Ghost Money Manor runs on a 5×4 grid with wins for three or more matching symbols on adjacent reels from the left. The standout mechanic is Link&Win, triggered by six or more Bonus Symbols. The feature starts with three spins, and the triggering symbols lock in place. Each new symbol that lands resets the counter to three. The round ends when no spins remain or when all 15 positions are filled. Power Ups can appear. Multiplier Upgrades boost all visible cash values by up to 10x, and Jackpot Upgrades lift every jackpot by one tier. Fixed jackpots are Mini (£50), Maxi (£100), Minor (£250), and Major (£1,000), with a £5,000 Mega on top. Overall win potential reaches up to 10,000x the bet.

A progress-based Bonus Wheel (boosted by Bonus Symbols) can pay out instant cash, a jackpot, or Free Spins. Three Haunted House Scatters (reels 1, 3, 5) grant a spin of the Free Spins Wheel for 10 to 30 spins, with an optional gamble and a Mystery Wheel cash award on a loss. 

Bonny’s Treasures

Bonny’s Treasures shifts to a pirate theme on a 5×3, 25-payline layout with high volatility. Symbols include Captain Bonny herself, treasure chests, rum barrels, and the Jolly Roger. Express Collect is the main hook: land Prize Symbols on reels 1 to 4 with a Collect on reel 5 to pay out line values or the jackpots. 

The Pick Bonus reveals 12 barrels; if three are matched, the player wins one of the jackpots (Mini 20x, Minor 40x, Major 400x, or the 5,000x Mega). If a Bonus symbol lands on reel one and a Collect symbol lands on reel five, the Octopus Bonus triggers. When it does, the octopus appears and pays out either a jackpot prize or a multiplier of up to 10x the triggering win.

Final Verdict: A Slot Designed to Be Calm Before the Storm

Olympus Storm, hosted on PokerStars, is a slot where theme and game mechanics match perfectly. Lightning strikes aren’t just a way to show Zeus’ power; it’s built into the gameplay to shape outcomes. Each layer of the Storm Levels adds a new dynamic, from Zeus Lightning’s random bolts to Wheel triggers, jackpots and Free Spins that have the capability to grow the grid or expand sessions.

This PokerStars slot doesn’t just put all the emphasis on the theme and smooth visuals while offering gameplay that feels unpredictable. Instead, the growing momentum, with the Storm Levels and combining features, makes the player feel like they are building their tools, which may come in handy.
