HelioPOPolis (AvatarUX) Slot Review
HelioPOPolis: Slot Overview
Egyptian-themed slots have been a staple in online casinos for decades, with countless developers putting their own spin on pyramids, gods, and golden treasures. AvatarUX, known for its signature PopWins mechanic, decided to take on this classic theme with HelioPOPolis, released on December 12, 2022. At first glance, another Egypt-inspired slot might not sound like the most original idea, but when blended with PopWins’ dynamic gameplay, escalating multipliers, and clever bonus mechanics, HelioPOPolis manages to carve out its own space in a crowded genre.
The game runs on a 5-reel grid with a starting 3-row layout, offering 486 ways to win. Thanks to the PopWins feature, reels can expand up to 6 rows high in the base game and even higher in free spins, pushing the paylines to a massive 65,536 ways to win. With high volatility, an RTP of 96%, and a maximum win of 20,000x the bet, HelioPOPolis promises a thrilling, albeit risky, ride through the sands of ancient Egypt. Players can stake anywhere between €0.20 and €125 per spin, making it accessible to casual spinners while also catering to high rollers.
Design and Graphics
Visually, HelioPOPolis delivers a polished presentation that feels both familiar and fresh. Instead of going overboard with the stereotypical golden shine, AvatarUX has leaned into an oil-painting-like quality that gives the backdrop a timeless, atmospheric charm. The pyramids rise majestically under a warm desert sky, and subtle animations breathe life into the desert setting without overwhelming the player.
The reels themselves feature a balanced mix of classic card royals (10–A) for low pays, three Egyptian-themed objects as medium symbols, and three Egyptian gods for the high-value ones. The gods, rendered with detailed linework and glowing accents, stand out as the most rewarding icons. Scarabs make their appearance as wilds, though they only show up during free spins, and mystery symbols add extra excitement by transforming into matching icons.
Overall, the presentation isn’t the flashiest among AvatarUX’s catalogue, but it strikes a perfect balance between recognizable Egyptian tropes and clean, modern visuals, ensuring that the focus remains firmly on the gameplay mechanics.
Gameplay Mechanics
At its core, HelioPOPolis thrives on the PopWins mechanic, a hallmark of AvatarUX titles. Each spin begins with a standard 3-row grid, but whenever winning symbols land, they pop off the reels and are replaced by two new symbols, expanding the reel’s height. This chain reaction continues until no new wins occur, meaning a single spin can dramatically increase the grid size and the number of ways to win.
Base Game Grid: 5 reels, 3 rows, 486 starting ways.
Max Base Expansion: 6 rows, unlocking 15,552 ways.
Free Spins Expansion: Up to 8 rows, maxing out at 65,536 ways.
The payout system works in both directions — wins are counted from left to right and right to left, significantly boosting hit potential. Symbol values are fairly standard:
Card royals pay 0.6x for five-of-a-kind.
Medium objects pay 1.5x–2.5x the bet for five.
High-value gods pay 3x–4x the bet for five.
It’s worth noting that five-of-a-kind wins only pay one way, even though paylines work in both directions. This keeps payouts balanced while still allowing frequent chain reactions.
Sound and Music
One of the standout elements of HelioPOPolis is its soundtrack, which adds significant atmosphere to the game. The base game features a haunting, mystical Egyptian-inspired melody, giving the reels an aura of mystery and grandeur. Once the free spins trigger, however, the tempo picks up dramatically, introducing techno beats fused with traditional Egyptian tones.
This clever switch in music mirrors the escalating tension of the gameplay, especially as multipliers rise and the reels stretch higher. The audio has been compared to a live performance at the pyramids, creating a perfect fusion of ancient mysticism and modern energy. Sound effects are sharp and impactful — every pop, multiplier increase, and scatter trigger adds to the sense of progression.
Bonus Features
HelioPOPolis is loaded with features that take advantage of the PopWins system while introducing extra layers of strategy and excitement.
Free Spins
Landing 3, 4, or 5 scatters triggers up to 7, 9, or 11 free spins, respectively. The number of starting ways and the multiplier level increase based on how many scatters triggered the round:
3 scatters: 7 spins, 2,048 ways, x5 multiplier.
4 scatters: 9 spins, 6,250 ways, x6 multiplier.
5 scatters: 11 spins, 15,552 ways, x7 multiplier.
Before free spins begin, players must choose between two modifiers:
Synced Reels – adjacent reels synchronize to display identical symbols.
Extended Win Symbol – a random symbol expands to cover the full reel when part of a win.
Free spins also introduce added wilds and mystery symbols, while the win multiplier increases by +1 with every win. If reels reach 8 rows, the multiplier rises by +2 per win, and +2 extra spins are awarded.
Base Game Unlock
If all reels reach the maximum 6 rows in the base game, players are awarded 2 free spins with either Synced Reels or Extended Win Symbols active.
Ante Bet
Players can activate the Ante Bet to increase their stake by 50%, which doubles the chance of triggering free spins.
Bonus Buy Options
For those who prefer instant action, HelioPOPolis offers three buy bonus options:
125x bet – Buy into free spins with one chosen feature.
125x bet – Buy into the other feature (Synced Reels or Extended Win Symbol).
1,000x bet – All features active from the start, with maximum potential unlocked.
Betting Options and Payouts
HelioPOPolis caters to a broad range of players with its flexible betting limits:
Minimum bet: €0.20
Maximum bet: €125
The game operates on high volatility, meaning wins won’t occur frequently, but when they do, they can be massive. The RTP sits at 96.0%, a fair benchmark for modern slots.
The maximum payout is an impressive 20,000x the bet, putting HelioPOPolis on par with other big-win PopWins slots. Achieving this requires chaining wins with maximum reel expansion, synced reels, and rising multipliers — a rare but thrilling prospect.
Conclusion
HelioPOPolis by AvatarUX successfully merges the timeless appeal of Egyptian slots with the modern innovation of the PopWins mechanic. While the theme may initially appear uninspired, the execution is anything but. The combination of cascading wins, expanding reels, and multiplier growth makes every spin feel loaded with potential. Add to this a free spins round with customizable modifiers, mystery symbols, synced reels, and the option to buy straight into the action, and you’ve got a slot that keeps engagement high from start to finish.
The visuals are polished without being overbearing, and the soundtrack is a genuine highlight, blending ancient mysticism with techno beats to amplify the drama. The 20,000x max win potential ensures that high-risk players will find plenty to chase, while the Ante Bet and bonus buy options give more control to those who prefer faster-paced sessions.
In the crowded world of Egyptian-themed slots, HelioPOPolis manages to stand out thanks to its seamless gameplay and explosive features.
