Gates of Olympus

Gates of Olympus is Pragmatic Play's take on the Greek mythology slot, and it has become one of the most played games in UK casino lobbies since its release in 2021. It uses a 6x5 grid with no paylines, paying for clusters of matching symbols anywhere on screen, combined with a multiplier system that can push wins well beyond what the base paytable suggests.

The game's central hook is its accumulating multiplier mechanic during free spins. Zeus drops multiplier orbs onto the grid during both the base game and the bonus round, but it is during free spins that they become dangerous. Multipliers do not reset between tumbles in the bonus, meaning they stack on top of each other until the round ends. That single mechanic is responsible for the game's 5,000x max win and for the big-win clips that made it a favourite among streamers and regular players alike.

How the Game Plays

Gates of Olympus uses scatter pays rather than traditional paylines. Any eight or more matching symbols anywhere on the reels register a win, regardless of where they sit on the grid. This opens the entire playing field and means that symbols do not need to connect along fixed lines. The result is a game where large clusters can form in unexpected patterns, and every position on every reel matters.

The symbol set includes coloured gems as lower-paying icons (green, blue, red and purple) with higher values assigned to items from Greek mythology: a ring, an hourglass, a chalice and a crown. The crown is the top-paying regular symbol. There is no wild symbol in Gates of Olympus. The only special symbol is Zeus's lightning bolt scatter, which triggers the free spins round.

Bets range from 20p to £125 per spin. The RTP is 96.5%, which sits above the industry average and is consistent across all bet levels. Volatility is high, which means the game distributes its returns unevenly. You will see long stretches without meaningful wins in the base game, then occasional clusters or multiplier-boosted payouts that recover the deficit and more. This is a game built for players who are comfortable with that rhythm.

Tumble Mechanic

Every win triggers a tumble. The winning symbols vanish from the grid and new symbols fall from above to fill the empty spaces. If those replacement symbols create another winning combination, they pay out and trigger another tumble. The sequence continues until no new wins appear.

In the base game, tumbles add a second chance element to each spin. A modest initial win can chain into something more substantial if the right symbols drop in. During free spins, the tumble mechanic is central to how the game builds its biggest payouts, because each tumble extends the window for multiplier orbs to accumulate.

Multiplier Orbs

This is the mechanic that defines Gates of Olympus and sets it apart from other scatter-pay slots. During any spin, Zeus can appear above the reels and drop multiplier orbs onto random positions on the grid. These orbs carry values ranging from 2x to 500x. In the base game, if a multiplier orb lands on the same spin as a winning combination, the orb's value is applied to that win.

The multiplier system shows its full potential during free spins. All multiplier values that land during a single free spin are added together, and that combined multiplier applies to every winning tumble within that spin. The accumulated multiplier does not reset between tumbles within the same spin. So if a 5x, a 10x and a 3x orb land during the same free spin, every winning combination across all tumbles in that spin is multiplied by 18x.

This stacking behaviour is how the 5,000x max win is reached. A run of tumbles with several large multipliers compounding across the sequence can turn small cluster wins into the game's ceiling payout. It is also why the free spins round can feel wildly inconsistent: some rounds deliver nothing because the multipliers land on dead spins, while others escalate rapidly when wins and orbs coincide.

Free Spins Round

Landing four, five or six scatter symbols anywhere on the grid awards 15 free spins. During the round, landing three or more additional scatters adds five extra spins, with no cap on retriggers.

The free spins round plays identically to the base game in terms of symbols and tumbles, but the multiplier behaviour changes significantly. Every multiplier orb that lands during the round adds to a running total displayed above the reels. That total multiplier applies to all wins for the remainder of the current spin and keeps building as new orbs appear. It resets only when a new free spin begins within the round (each of the 15 spins starts with a fresh multiplier count), but within a single spin and its associated tumble chain, the multiplier only goes up.

This creates a dynamic where a single free spin that triggers a long tumble chain with several multiplier orbs landing along the way can produce a payout dramatically larger than anything the base game offers. The tension during each free spin comes from watching the multiplier climb while hoping the tumble chain holds.

Ante Bet and Buy Feature

Gates of Olympus offers two options for players who want more frequent access to the bonus round.

The Ante Bet increases your total stake by 25% and doubles the probability of landing scatter symbols. At a £1 bet, this raises the cost to £1.25 per spin. Whether this trade-off works in your favour depends on session length and bankroll management. It gets you into free spins more often, but each spin costs more, so the theoretical return evens out over time.

The Buy Feature lets you purchase immediate entry to the free spins round for 100x your current bet. A £1 base bet means paying £100 for 15 free spins. The expected value of a purchased round matches the expected value of triggering it naturally, so this is a time-saving option rather than a mathematical advantage. It appeals to players who prefer to skip the base game volatility and go directly to where the game's payout potential is concentrated. Note that the Buy Feature is not available in all jurisdictions.

Gates of Olympus Compared to Similar Slots

The most direct comparison is Sweet Bonanza, which shares the same developer, grid size, scatter pays mechanic and tumble feature. Sweet Bonanza uses multiplier bombs during free spins in a similar way, though its max win ceiling is significantly higher at 21,175x, and its volatility sits slightly lower. If you enjoy the core loop of Gates of Olympus but want a different theme and a wider payout range, Sweet Bonanza is the obvious alternative.

Big Bass Bonanza takes a completely different approach from Pragmatic Play's Reel Kingdom partnership, using traditional paylines and a money collect mechanic rather than scatter pays. It suits players who prefer a more structured reel format.

Sugar Rush is another Pragmatic Play title that uses the scatter pays and tumble mechanic on a larger 7x7 grid, with a multiplier system that builds in a different way: winning positions on the grid carry increasing multiplier values across consecutive wins. It suits players who like the core Gates of Olympus loop but want a different payout structure.

Mobile and Technical Performance

The game is built in HTML5 and runs well on mobile devices. In portrait mode, the 6x5 grid compresses to fit the screen width without losing symbol clarity, and the tumble animations remain smooth on most modern phones. Zeus's multiplier orb animations are visually distinct enough to read at smaller sizes, and the accumulated multiplier total stays visible during free spins.

Bet controls are accessible through a collapsible menu, and autoplay settings (where available) carry over between sessions. The scatter pays format works well on mobile because there are no payline indicators to clutter the display. Wins are counted across the full grid, and the visual feedback is clear regardless of screen size.
