The Megaways mechanic revolutionized online slots when Big Time Gaming introduced it in 2016. Since then, hundreds of titles have adopted this system, creating a distinct category within the iGaming market. This guide breaks down what makes these games different, which titles consistently perform well, and what players need to know before spinning.
Megaways Slots Explained + Top 5 List
Megaways slots use a random reel modifier that changes the number of symbols appearing on each reel with every spin. Instead of fixed paylines, these games offer anywhere from a few hundred to over 117,000 ways to win. The mechanic has become so popular that major providers license it from Big Time Gaming to create their own variations.
The following five titles represent the most played and highest-rated megaways slots in 2025, based on session data from UK and European operators. Each offers unique features while maintaining the core variable reel system.

Play Megaways Slots NowBonanza Megaways
Released in 2016, Bonanza remains the benchmark for this category. The mining theme supports six reels with two to seven symbols each, creating up to 117,649 ways to win. The game includes a cascading wins feature where successful combinations disappear and new symbols drop down. Four scatter symbols trigger 12 free spins with an unlimited win multiplier that increases by 1x after each cascade.
RTP sits at 96%, with high volatility meaning extended dry spells followed by potentially large wins. The maximum payout reaches 10,000x the stake. Most UK-licensed casinos feature this title, and it consistently ranks in the top ten most-played slots across multiple platforms.
Extra Chilli Megaways
This sequel to Bonanza adds a gamble feature that lets players risk their free spins bonus for more initial spins or a higher starting multiplier. The Mexican street market theme uses the same reel structure as Bonanza but introduces a feature drop option where players can buy the bonus round for 50x their stake.
The base game volatility matches Bonanza, but the gamble mechanic introduces additional risk. Players who activate the feature drop bypass the base game entirely, which suits those comfortable with higher variance. The maximum win potential reaches 20,000x, double that of the original.
Gonzo's Quest Megaways
NetEnt partnered with Big Time Gaming to transform their popular Gonzo's Quest slot into a Megaways version. The Peruvian temple theme keeps the original's earthquake feature, where blocks fall instead of spinning reels. The megaways slots game engine adds up to 117,649 ways to win across six reels.
Free falls (the game's version of free spins) trigger with three scatters and start with 9 rounds. The multiplier increases with each cascade, reaching 15x in the base game and 15x in the bonus round. RTP varies between 95.77% and 96% depending on the operator. The combination of familiar branding and modern mechanics makes this a top choice for both new and experienced players.
Monopoly Megaways
Big Time Gaming secured the Monopoly license to create one of the most feature-rich slots in this category. The game uses the standard six-reel structure but adds a bonus reel above the middle four reels. Landing four or more free parking symbols triggers the bonus, with additional symbols adding extra spins.
What separates monopoly megaways slots from competitors is the Houses and Hotels feature. During free spins, collecting green house symbols builds houses on properties. Four houses convert to a hotel, which awards a random multiplier up to 5x. The maximum win reaches 14,700x with an RTP of 96.5%. The multiple bonus layers create longer sessions compared to simpler Megaways titles.
Buffalo King Megaways
Pragmatic Play's entry into the Megaways market uses the popular buffalo theme with a twist. The game offers up to 200,704 ways to win through a unique reel layout featuring four rows on reels one and six. The multiplier system differs from competitors by using a progressive multiplier that increases in both directions during free spins.
Four scatters award 12 free spins with the option to gamble for more. The volatility ranks as extreme, with the base game offering infrequent wins but substantial bonus potential. Maximum payout reaches 10,000x, and the RTP sits at 96.06%. The extended ways to win and bidirectional multipliers attract players looking for mechanical variation within the Megaways format.
What Megaways Slots Are & How They Work
The Megaways mechanic operates through a random number generator that determines how many symbols appear on each reel before every spin. Reels can display between two and seven symbols, creating a constantly changing number of active paylines. The system calculates potential winning combinations by multiplying the number of symbols on each reel together.
A six-reel setup where each reel shows seven symbols produces 117,649 ways to win (7×7×7×7×7×7). If the next spin shows a mix of two, five, four, six, three, and seven symbols, the ways to win drop to 5,040 (2×5×4×6×3×7). This variance creates the core appeal for how do megaways slots work in practice.
Most titles include cascading reels, where winning symbols disappear and new ones drop from above. Each cascade counts as a separate spin without additional cost, and many games apply an increasing multiplier to consecutive cascades. The combination of variable reels and cascades produces extended winning sequences that traditional fixed-line slots cannot replicate.
Big Time Gaming holds the patent for the Megaways mechanic and licenses it to other providers for a percentage of revenue. This explains why slots megaways titles appear across multiple studios while maintaining consistent core functionality. Licensed versions must meet specific technical standards, ensuring players get a similar experience regardless of the developer or theme.
How to Play a Megaways Slots Game
Setting up a spin requires selecting a stake amount, which typically ranges from £0.10 to £20 per spin on UK-licensed sites. The total bet multiplies across all ways to win automatically, so a £1 bet at 117,649 ways costs £1 total, not £1 per way. This structure differs from traditional slots where players select both coin value and number of active lines.
Basic Megaways Gameplay Steps:
- Choose stake amount within the available range
- Click spin and wait for reels to stop
- Winning combinations pay out based on the paytable
- Cascades remove winning symbols and drop new ones
- Repeat until no new wins appear
- Return to step 2 for the next spin
The paytable shows payouts based on symbol combinations across adjacent reels, starting from the leftmost position. Three or more matching symbols on consecutive reels trigger a win. Some titles include right-to-left wins, effectively doubling the ways to win, but this appears in the game rules before play begins.
Most how to play megaways slots guides mention the autoplay function, which runs consecutive spins at the chosen stake. UK regulations require loss limits on autoplay, typically capping it at £100 or 100 spins, whichever comes first. Players can set win and loss limits through the game interface before activating autoplay.
Understanding volatility matters more with Megaways titles than traditional slots. High volatility means fewer winning spins but larger average payouts when wins occur. A megaways slots list ranked by volatility helps players match games to their bankroll and playing style. Sessions on high volatility games require larger starting balances to weather extended losing streaks.
Licensing & Security
All megaways slots available to UK players operate under licenses from the UK Gambling Commission. These licenses require RNG certification from approved testing labs like eCOGRA or iTech Labs. The certification process verifies that the random reel modifier produces truly random results and matches the published RTP within statistical margins.
Operators display their license number at the bottom of every page, typically formatted as a five-digit number with verification links. Licensed casinos undergo regular audits covering game fairness, player fund segregation, and responsible gambling measures. The UKGC can suspend licenses immediately if audits reveal violations, providing players with regulatory protection beyond just game fairness.
Games from licensed providers show their certification details in the paytable or information screen. This includes the RTP percentage, maximum win potential, and volatility rating. Legitimate online slots operations cannot alter these values without invalidating their certification. Players should verify these details match the provider's official specifications before playing.
Security extends beyond licensing to include data encryption and payment processing. Sites offering megaways slots must use SSL encryption for all transactions and personal data transfers. Payment methods go through PCI DSS certified processors, separating financial data from the gaming platform. Two-factor authentication adds another layer of account security, particularly important for mobile gaming where devices can be lost or stolen.
