HelioPOPolis Features

HelioPOPolis offers a variety of special features that enhance gameplay and increase winning potential.


The PopWins mechanic is a unique feature where winning symbols disappear and are replaced by two new ones. This process continues as long as new wins are formed, with the rows resetting to 3 when the winning streak ends. In the free spins round, the rows don’t fully reset between spins, instead, they go down to the present shortest reel height.

Wild Symbol

The Wild Symbol, represented by a golden and blue scarab, appears only in the free spins round. It substitutes for all symbols, increasing the chances of forming winning combinations.

Scatter Symbol

The Scatter Symbol, depicted as a pyramid with its top chopped off, triggers the free spins round when 3, 4, or 5 of them land on the reels. The free spins start with a setup of 4, 5, or 6 rows, depending on the number of Scatters that triggered the round.

Mystery Symbol

The Mystery Symbol, represented by a question mark, also appears only in the free spins round. After landing, all Mystery Symbols reveal the same symbol, potentially leading to significant wins.

Ante Bet

Players can double their chances of triggering the free spins round by purchasing the Ante Bet for 25% of the original bet.

Base Game Unlock

Unlocking all reels to 6 rows high in the base game awards 2 free spins and one of two features: Synced Reels or Expanded Win Symbols. Synced Reels land identical symbols for a higher chance of winning, while Expanding Win Symbols expand to cover the entire reel when they’re part of a win.

Pre-Bonus Game

Before the Free Spins round, players get to choose one of two rewards in the Pre-Bonus game: Synced Reels or Expanded Win Symbol with Guaranteed Wilds. The number of triggering Scatters determines the number of free spins and the starting multiplier.

Free Spins

The Free Spins round starts with a certain number of rows and ways to win, depending on the number of triggering Scatters. The reels don’t reset to the starting heights between spins, and there’s a win multiplier that increases by 1 for every PopWin. Fully unlocking all reels 8 rows high awards an extra 2 spins and adds +2 to the win multiplier.

Bonus Buy

Players can purchase the free spins feature at different bet multipliers. They can also choose between the Big Sync and Great Wilds options, or pay 1000X the bet for a session with both features and the starting position of triggering the feature with 5 Scatters.

These features contribute to the game’s appeal by offering various ways to win and strategize. Players can choose to purchase the Ante Bet or Bonus Buy to increase their chances of triggering the special features and potentially winning big.

HelioPOPolis Conclusion

HelioPOPolis is a captivating online slot game that truly stands out with its unique PopWins mechanic. The game’s high volatility and impressive max win of 20,000x the bet make it a thrilling choice for those seeking big rewards. The expanding rows feature, which can go up to 8 rows in the free spins, adds an exciting twist and increases your chances of hitting those massive wins.

In my opinion, HelioPOPolis offers a top-notch gaming experience that combines innovative gameplay with high-quality graphics and sound design. Compared to other slots in the genre, it definitely ranks high in terms of entertainment value and potential winnings. Although the theme might not be the most coherent, the fun and excitement you get from playing more than make up for it.
