At Admiral Casino, our extensive library of online slots offers something for every type of player. Whether you enjoy the fast-paced action of modern video slots, the nostalgia of classic fruit machines, or the excitement of jackpot games, you’ll find it all here.

Before we dive into the most popular slot genres on our platform, it helps to understand how online casino work, and what game mechanics like RNG, RTP, volatility, and paylines actually mean.

How Do Online Slots Work?

Online slots are built to be simple to play, but they rely on a few core mechanics that influence your experience and potential outcomes.

Random Number Generator (RNG) – What it is and why it matters

Slot results are generated by a Random Number Generator (RNG). This is a system that produces outcomes designed to be unpredictable and not influenced by previous spins. In other words, each spin is treated as its own event.

Paylines, ways to win, and symbols

Slots pay prizes when symbols land in specific patterns. Depending on the game, wins might be based on:

Fixed paylines (set patterns across the reels)
Adjustable paylines (you choose how many paylines to activate)
Win Ways / ways-to-win systems (wins calculated by symbol combinations rather than traditional lines)

Games also use different symbol types, such as:

Wilds (often substitute for other symbols to help form wins)
Scatters (may trigger free spins or bonus rounds, sometimes without needing a payline)
Multipliers (can increase winnings during a feature or bonus)

RTP and volatility (variance)

Two terms you’ll see often in “best online slots” searches are:

RTP (Return to Player): The theoretical percentage a game is expected to return over a very large number of spins. It’s a long-term average, not a promise for individual sessions.
Volatility (Variance): Describes the balance between win frequency and win size.

Low volatility: smaller wins more often

High volatility: wins may be less frequent, but can be larger when they land

If you prefer steady play, you may enjoy low-to-medium volatility slots. If you’re drawn to bigger feature potential, high volatility and jackpot slots may be more your style.

Slot Categories at Admiral Casino

Below are the main slot types available on Admiral Casino — with a quick explanation of what makes each one different, and why players look for them.

Classic Slots

Classic slots are inspired by traditional fruit machines and offer straightforward gameplay. They’re often played on three reels, with familiar symbols like fruits, bells, and bars. Many players enjoy classic slots for their simplicity, faster pace, and easy-to-follow features.

We suggest giving 777 Burn ‘Em Up a try — a retro-style slot with a fiery twist, offering classic gameplay with modern rewards.

Video Slots

Video slots represent the evolution of online slot gaming. Featuring five or more reels, rich graphics, and immersive themes, these games often include bonus features such as free spins, wilds, multipliers, and interactive mini-games.

Some must-plays include:

Starburst – A fan-favourite space-themed slot with expanding wilds and respins.
Eye of Horus – An Egyptian adventure packed with free spins and symbol upgrades.
Rainbow Riches – A legendary Irish-themed slot with multiple bonus rounds.

If you’re searching for video slots with Free Games or bonus features, this is the category most players start with.

Progressive Jackpot Slots

For players who enjoy jackpot mechanics, progressive slots use a prize pool that can grow as the game is played. These jackpots may be linked across a network of games (depending on the title and configuration), which can create larger headline prizes over time.

Try:

King Kong Cash Jackpot King – A jungle-themed progressive slot with jackpot potential.
Mega Joker – A classic-style slot with a jackpot twist.

Megaways Slots

Megaways slots are designed to create variety from spin to spin. Instead of fixed reels, Megaways games often use variable reel layouts, which can result in a changing number of ways to win each round.

Try:

Fishin’ Frenzy Megaways – Fishing-themed Megaways gameplay with plenty of Free Games.
Mustang Gold Megaways – A higher-volatility slot with Free Games and Cash Collects features.

Exclusive Slots

Explore games available only at Admiral Casino, designed with unique features and tailored for our players. From bespoke themes and mechanics such as those used on Strike It Gold – Win Ways, to exclusive fruit machine-style slots like Feel the Flutter, our exclusive slots offer fresh gameplay and distinctive features.

If you’re looking for more games from well-known developers like Evolution, NetEnt or IGT, you’ll also find a broad selection across the wider casino lobby on Admiral Casino.

What Makes Megaways Slots Unique?

Megaways slots change traditional gameplay with dynamic reel structures, which can create thousands of possible ways to win. But what does that mean in practice?

Dynamic reels: Many Megaways slots vary the number of symbols on each reel per spin, changing the number of potential combinations each round.
Cascading reels: Some titles use cascading mechanics, where winning symbols disappear and new symbols fall into place, potentially creating multiple wins from a single paid spin.
Bonus features: Free spins, multipliers, and bonus rounds are common, and may be designed to work alongside cascading or expanding mechanics.
Variable ways to win: Rather than a fixed number of paylines, Megaways-style games typically pay for symbol combinations across adjacent reels (rules vary by game).

Some of the most played Megaways slots on our platform include Big Bass Bonanza Megaways and Eye of Horus Megaways.

Progressive Jackpots vs. Fixed Jackpots

Understanding jackpot types can help you choose the right games.

Progressive Jackpots

These jackpots can increase over time as the game is played, until a win is triggered. Depending on the title, jackpots may be linked across a network of games, which can help prize pools grow.

Popular examples include Diamond Link titles such as:

Fixed Jackpots

Fixed jackpots use set prize structures. In many games, the prize outcome depends on how a bonus feature is triggered or how special symbols/conditions are met during the feature.

At Admiral Casino, you’ll find a variety of both progressive and fixed jackpot slots.

Understanding Paylines, RTP, and Volatility in Online Slots

When playing online slots, three key mechanics determine how games function and what kind of experience you can expect: paylines, RTP (Return to Player), and volatility. Understanding these elements can help you choose the right slot for your gaming style.

What Are Paylines and How Do They Work?

Paylines are how winning patterns or symbol combinations are counted in a slot. When matching symbols land in a valid pattern, you win a payout based on the game’s paytable.

Fixed paylines: Always active — you bet on all available paylines each spin.
Adjustable paylines: Some games allow you to choose how many paylines to activate.
Win Ways slots: Wins are calculated via symbol combinations rather than fixed paylines (e.g., Megaways-style games)

Rules can vary (for example, whether symbols must land left-to-right). Always check the paytable for the exact rules.

What Is RTP and Why Does It Matter?

RTP is the theoretical percentage of total bets a game is expected to return over time. It is not a guarantee of individual results.

Example: a 94% RTP slot means that, over time and across many spins, £94 may be returned for every £100 wagered on average.

What Is Slot Volatility?

Volatility describes risk level and influences how often and how much a slot pays out:

Low volatility: frequent, smaller wins
Medium volatility: a balance of frequency and win size
High volatility: less frequent wins, potentially larger payouts

Always check the paytable/info to understand a slot’s RTP and volatility before you play.
