The Evolution of the Slot Machine
The world of online slots has evolved dramatically from the classic, mechanical “fruit machines” of old. While the core objective—matching symbols to win—remains the same, the mechanics and features have become increasingly sophisticated, creating distinct categories of games tailored to different player preferences.
To illustrate these differences, we can look at a game that exists in multiple forms across these categories: Eye of Horus. With its enduring Ancient Egyptian theme, Eye of Horus serves as a perfect case study, demonstrating how the same core concept can be re-engineered to provide three entirely different experiences, each with its own set of rules, risks, and rewards.
This guide will break down the mechanics of three major types of slot games—Fixed Payline, Megaways, and Progressive Jackpot—using the Eye of Horus series as a consistent example. By understanding the fundamental differences in how these games work, you can make a more informed choice about which type of slot is right for you.
The Classic Approach – Fixed Payline Slots
The original and most traditional form of online slot machine is built on the concept of fixed paylines. These games are a modern adaptation of classic mechanical slots, designed for players who appreciate straightforward, predictable gameplay.
How They Work
A “payline” is a predetermined pattern across the reels where a player must land a specific number of matching symbols to secure a payout . In a fixed payline game, these lines are always active, meaning you are betting on every single potential winning combination with each spin . This removes the frustration of missing a win on a line you didn’t bet on, but it also means the minimum stake per spin is higher than if you could bet on a single line.
The goal is simple: land a winning combination of symbols on one of these fixed paylines, typically from the leftmost reel to the right .
The Eye of Horus Example: The original Eye of Horus slot is a classic example of this category. It is a five-reel, three-row game with 10 fixed paylines. The gameplay is centred around its core bonus features, such as the expanding Horus wild symbol and a free spins round with a symbol upgrade mechanic, which enhances winning potential.
Player Profile and Payouts
Fixed payline games like the original Eye of Horus are known for their balanced experience. They have a medium-to-high volatility, which means you can expect a mix of smaller, more frequent wins and occasional, larger payouts, especially during the free spins feature. The Return to Player (RTP) for the original
Eye of Horus is a respectable 96.31%, a figure that is considered above the industry average.
This type of slot is ideal for players who want a more structured and predictable gaming session. It is a game for those who enjoy the classic feel of spinning reels and are content with more frequent, albeit smaller, wins as they chase the game’s internal top prize .
The Dynamic Revolution – Megaways Slots
Megaways slots represent a significant leap in slot machine innovation. Developed by Big Time Gaming, the Megaways engine is a “random reel modifier” that transforms the entire playing experience into something far more dynamic and unpredictable .
How They Work
Instead of having a fixed number of rows, the Megaways engine randomly alters the number of symbols on each reel with every single spin . This dynamic reel structure means that each spin offers a different number of potential winning combinations . The traditional concept of paylines is replaced by a “ways-to-win” system where payouts are triggered by landing matching symbols on adjacent reels, regardless of their position.
The total number of ways to win on any given spin is calculated by multiplying the number of symbols on each reel together. While the Megaways engine can produce up to 117,649 ways to win on some games, this number varies from title to title . Many Megaways slots also include a cascading reels feature, where winning symbols are removed from the screen and new symbols drop into place, allowing for multiple wins from a single spin.
The Eye of Horus Megaways Example: Eye of Horus Megaways is a game built on this dynamic principle. Its reels are designed to produce up to a maximum of 15,625 ways to win, which is less than some other Megaways titles but still far more than its fixed payline counterpart. The game incorporates the cascading reels feature along with the familiar symbol upgrades from the original, creating a fast-paced and exciting experience.
Player Profile and Payouts
Megaways games are typically highly volatile . This means wins are less frequent, but they can be significantly larger when they do hit . The Return to Player (RTP) for Eye of Horus Megaways is often reported as being around 95.49% , a slight decrease from the original but still within a respectable range. The maximum payout potential for
Eye of Horus Megaways is cited as being as high as 10,000 times the stake.
This type of game is perfect for a player who craves a high-risk, high-reward experience . It requires a larger bankroll to weather the longer periods between wins but offers the potential for enormous payouts from a single lucky spin.
The High-Stakes Pursuit – Jackpot King Slots
The third category, progressive jackpot slots, is less about a change in the core spinning mechanic and more about an additional layer of potential reward. These games are tied into a communal, networked prize pool that can grow to life-changing sums .
How They Work
Progressive jackpot games work by taking a small portion of every bet placed on a qualifying slot across a network of casinos and adding it to a shared prize pool . This pool, or jackpot, continues to grow until a lucky player triggers it, at which point it resets to a base amount and begins to grow again .
Blueprint Gaming’s Jackpot King network, for example, features three progressive jackpots: the Royal Pot, Regal Pot, and the grand Jackpot King . The bonus feature that can lead to these jackpots is typically triggered randomly on any spin. When it hits, the player is taken to a special bonus round where they can spin for a chance to win one of the three prizes.
The Eye of Horus Jackpot King Example: The Eye of Horus Jackpot King is a variant of the original fixed payline game. It retains the same 5×3 reel structure and 10 paylines , but with the addition of the Jackpot King progressive network overlay. This means players have a shot at both the game’s standard payouts and a potentially massive jackpot.
Player Profile and Payouts
There is a crucial trade-off when playing progressive jackpot slots: the game’s base RTP is typically lower than its standard counterpart . This is because a percentage of every bet is being diverted to fund the progressive jackpot, which means there is less money in the pool for smaller, more frequent payouts .
This type of game is defined by its high volatility and risk . It is the perfect choice for a player whose primary motivation is the pursuit of a life-changing win . You must be prepared to accept a less favourable RTP and potentially long periods of play without significant wins, all in the hope of triggering the jackpot bonus round .
Choosing Your Game: A Player’s Guide
Choosing the right slot game is not a matter of finding one that is objectively “best,” but rather one that aligns with your personal risk tolerance, budget, and desired gameplay experience.
Key Factors to Consider
- Volatility: This is arguably the most important factor.
- Medium-to-High Volatility (Fixed Payline): A balanced experience with a mix of smaller and larger wins. Ideal for players who want to manage their bankroll while still having a shot at a decent payout.
- High Volatility (Megaways & Jackpot King): A more extreme experience with fewer but potentially massive wins. Requires a larger bankroll and a higher tolerance for risk.
- Return to Player (RTP): This is the theoretical percentage the game pays back over millions of spins .
- A higher RTP (like the original Eye of Horus‘s 96.31%) suggests a better long-term return on your money in the base game .
- A lower base game RTP (common in progressive jackpots) means you are paying a small “tax” on every spin for a chance at a much larger, less frequent payout .
- Gameplay:
- Classic Paylines: A more structured and predictable experience for players who enjoy simplicity and a clear understanding of the game’s mechanics .
- Megaways: A fast-paced and unpredictable experience with dynamic reels and cascading wins for players who love high-energy action .
- Jackpot King: A constant chase for the big prize. This is for players who are motivated by the dream of a life-changing win, even if the odds are astronomical .
