What are Megaways slots?

Megaways slots are a unique category of online slot games. They are built around a reel modifier system that changes the number of symbols appearing on each reel during every spin.

Traditional slots usually have a set number of paylines, often between 10 and 40. Megaways, on the other hand, can generate up to 117,649 different winning combos in a single spin. This mechanic makes things feel unpredictable and makes sure that no two spins are the same.

Megaways games have higher volatility and faster gameplay, and the chance to win bigger prizes is higher than standard slots. These advantages are because the layout of the reels changes all the time.

These games often feature cascading reels, multipliers, free spins and other unique bonus rounds. All of these features add even more variety and excitement.

The result is a style of play that is enjoyed by both casual players looking for entertainment and experienced slots fans looking for big payouts. These are the reasons for Megaways’ continued popularity across the world.

Megaways slot mechanic licensing

In 2016, Big Time Gaming (BTG) was the first company to introduce the Megaways mechanic. After the great success of early games like Bonanza Megaways and Extra Chilli Megaways, BTG saw that it had the potential to reach more people. So, the company decided against keeping the system exclusive and started licensing the technology to other top software developers.

Blueprint Gaming, Pragmatic Play, Red Tiger and NetEnt are just a few of the providers that benefited from this open partnership and added the Megaways engine to their own popular games. This approach made it possible to build a lot of different themes, features and play styles on the same foundational mechanic. This quickly increased the number of Megaways slots available at online casinos.

One big reason why the model has been so popular is licensing. Today, almost every major software developer has contributed to the Megaways library. This means that players can enjoy both brand-new games and updated versions of old classics on hundreds of different casino platforms.

Megaways slots features and bonuses

Megaways slots are unique because they have a lot of different mechanics that make gameplay more dynamic and rewarding. These features not only increase excitement but also create opportunities for bigger wins. As a result, these games remain a popular choice among players. These are the most common features you’ll see:

Cascading reels: When you get a winning combination, the symbols that were part of it disappear and new ones fall into place. This chain reaction can keep going, giving you more than one win from a single spin.
Free spins with multipliers: Getting enough scatters will often trigger free spins along with unlimited multipliers that keep adding up with each cascade. This can turn small wins into massive payouts.
Expanding wilds: Some wilds can cover entire reels. This, in turn, can increase the chances of getting large Megaways combinations and improve the overall win frequency.
Mystery symbols: These are hidden icons that change into the same symbol when they are unveiled. This makes the game more unpredictable and enhances the possibility of getting big lineups across reels.
Bonus buy options: This feature is only found in some Megaways slots. With it, players can purchase instant access to free spins or bonus rounds instead of waiting for them to occur naturally.
Progressive jackpots: These can be found in some Megaways games. These jackpots grow over time across multiple casinos. This gives players the chance to win huge sums of money with just one spin.
Reel modifiers: Some games have random modifiers that can appear during base gaming. These can be extra wilds, symbol swaps or guaranteed scatters.
Locking symbols: During some bonus rounds, winning symbols stay in place while the reels keep spinning. This boosts the chances of getting bigger combinations.
Dual-action reels: Although less common, it’s an exciting feature in which two sets of reels spin at the same time. This doubles the potential winning opportunities.

Megaways slots with highest RTP

These are some of the Megaways slots with the best RTP:

White Rabbit Megaways (97.24%)
Extra Chilli Megaways (96.82%)
Big Bass Bonanza Megaways (96.70%)
The Dog House Megaways (96.55%)
Medusa Megaways (96.28%)

Players should remember that RTP is a long-term statistical average, not a guarantee of individual outcomes.

Top software providers for Megaways slots

Many top software companies now produce Megaways slots, and each brings its own themes, gameplay and innovations to the format. The following providers are recognised as the most important contributors to the Megaways library:

Big Time Gaming (BTG): Created the Megaways mechanic and developed classics like Bonanza Megaways, Extra Chilli Megaways and Who Wants to Be a Millionaire Megaways.
Pragmatic Play: Known for making games like Buffalo King Megaways, The Dog House Megaways and Big Bass Bonanza Megaways, with amazing graphics and features.
Blueprint Gaming: The master of branded and franchise slots. They have adapted hits like The Goonies Megaways, Fishin’ Frenzy Megaways and Eye of Horus Megaways.
Red Tiger Gaming/NetEnt: Brought new life into classics with Gonzo’s Quest Megaways and Piggy Riches Megaways, delivering cinematic gameplay experiences.
Relax Gaming: Pioneered feature-packed games like Temple Tumble Megaways and Money Train Megaways, which have immersive themes and high volatility.
Microgaming: Added 9 Pots of Gold Megaways, Poseidon Ancient Fortunes Megaways and the jackpot-driven Mega Moolah Megaways to their line of slots.
Playson: Their games, like Legend of Cleopatra Megaways, are known for their fantastic images and captivating mechanics.
SG Digital (formerly Barcrest): Enhanced classic series with Rainbow Riches Megaways, which fans of the long-running slot series enjoyed.
GameBurger Studios: An official Microgaming partner that makes unique Megaways games such as 9 Pots of Gold Megaways.
Triple Edge Studios: Another company that works with Microgaming to make great games like Poseidon Ancient Fortunes Megaways.

These companies are the backbone of the Megaways market. They make sure that players in the UK have access to a wide range of themes, levels of volatility, and bonus features.

What’s the difference between Megaways and Megapays?

Megaways and Megapays are not the same thing, even though their names sound alike.

Megaways is a reel modifier system. Every time the reels spin, the number of symbols that land on them changes. This creates a huge number of possible winning combinations. Most of the time, there are up to 117,649 ways to win these games. The mechanic is all about giving players more action-packed spins and different variety and volatility.
Megapays, on the other hand, is a progressive jackpot system. It links some Megaways slots to a network of jackpots that are shared by several casinos. Every time you spin a Megapays slot machine, a small amount is added to one of four prize levels: Mini, Midi, Major and Mega. The Mega Jackpot can get as high as a million pounds, giving players the chance to win mouth-watering prizes.

In the UK, these are some of the most famous Megapays slots:

Bonanza Megapays: The original BTG hit, but now it has a bigger jackpot potential.
Who Wants to Be a Millionaire Megapays: A slot game based on the popular game show of the same name. It features progressive prizes.
Irish Riches Megapays: A slot game with an emerald theme that is full of jackpots and Megaways.
Mystery Reels Megapays: Red Tiger’s take on classic fruit games with big jackpots.
Star Clusters Megapays: A colourful cluster-pay slot game with multiple levels of a progressive jackpot.

In short, Megaways adds variety to gameplay, while Megapays adds jackpot prizes. Some slots even use both systems together, giving players thrilling spins with the chance to win millions of pounds.

Advantages of Megaways slots

Here are the advantages of Megaways slots:

Thousands of winning combinations per spin: There are up to 117,649 ways to win on every spin, due to the dynamic reel system. Compared to regular slots with set paylines, this gives you considerably more chances to win.
Exciting, unpredictable gameplay: The reel layout changes with each spin, so no two rounds are the same. This unpredictability keeps players engaged and builds suspense.
High maximum win potential: Many Megaways slots have top payouts of 10,000x or more. This makes them very attractive to players who want to win big.
Wide selection of themes and providers: Megaways games cover almost every theme, from ancient Egypt to branded TV shows. Multiple providers now license the mechanic, so you have a lot of options.
Frequent new releases: Developers are always adding new games to the Megaways library. This means that players can always try out new games and never run out of options.

Disadvantages of Megaways slots

Here are the disadvantages of Megaways slots:

High volatility might not be good for casual players: A lot of Megaways slots are designed with big swings in mind. This can mean that you don’t win for a long time, which some players may find frustrating.
Lower RTP than some classic slots: Megaways games usually have an RTP of 95% to 96%, which is still pretty good. Higher payouts can be found in classic slots like Blood Suckers.
Bonus features can be complex for beginners: Cascades, multipliers and modifiers can overwhelm new players at first. Unlike easy three-reel slots, this gameplay takes some time to learn how to play.
Bonus wagering requirements may be high: For example, casino offers for Megaways games often have strict playthrough terms. This makes it harder for players to turn bonus winnings into real money.
