Royal Mint Megaways wins over Bonanza Megaways on max win potential (40,000× stake vs 26,000× stake — a 14,000× gap). Bonanza Megaways leads on RTP at approximately 96% vs 96.53% — wait, Royal Mint edges RTP; choose Bonanza Megaways if you want the widely recognised original Megaways mechanic; choose Royal Mint Megaways if you want a higher max-win ceiling for UK players.
Both are Big Time Gaming titles sharing the same 117,649-payline Megaways engine and high volatility, but the specs reveal meaningful differences in ceiling and RTP.

Released in 2016, Bonanza Megaways established the Megaways format that dozens of titles have since followed. Its mining theme drives a cascading-reels structure where winning symbols explode and new ones fall in, with an unlimited multiplier that climbs by one with each successive cascade during the free spins round. The four-reel top strip adds extra symbol positions, and a scatter-triggered free spins bonus includes a retrigger option. In our testing, the unlimited cascade multiplier is the engine that generates the game's most significant returns, though it requires a sustained cascade run to activate meaningfully. See Bonanza Megaways review for a full mechanic breakdown.
Released in 2020, Royal Mint Megaways applies the same 117,649-way Megaways engine to a luxury British mint theme. It retains the cascading-reels mechanic but layers in a distinct bonus structure; the public paytable does not disclose specific scatter counts or free spin numbers beyond what Big Time Gaming publishes. The game's 40,000× max win ceiling is its headline figure — significantly above Bonanza's 26,000×. In our testing, Royal Mint felt structurally similar to Bonanza but with a more subdued visual palette and a marginally higher RTP of 96.53%.

Royal Mint Megaways edges it on Royal Mint Megaways rtp: 96.53% vs approximately 96%, a roughly 0.53 percentage-point advantage that compounds over long sessions.
Royal Mint Megaways wins decisively here: 40,000× stake vs Bonanza's 26,000×, a 14,000× difference in theoretical ceiling.
Both are classified as high volatility — consult Slot Volatility Explained if that category is new to you — so neither is the gentler option; Bonanza's longer track record provides more published session-variance data for comparison.
Bonanza Megaways takes this: its unlimited cascade multiplier during free spins is among the most studied mechanics in the Megaways catalogue, giving it an edge in bonus depth over Royal Mint's feature set.
Play Bonanza Megaways if you want the foundational Megaways experience with an unlimited cascade multiplier and a well-documented volatility profile. Its 2016 release means session data and community knowledge are extensive, which suits players who prefer to enter a bonus round with realistic expectations about frequency and depth.
Play Royal Mint Megaways if the higher max-win ceiling of 40,000× and a marginally better RTP of 96.53% are your tiebreakers. The luxury theme also suits players who find the mining aesthetic of Bonanza less engaging, while the core Megaways mechanic remains familiar.
Play both if you want to compare how the same Megaways engine behaves across two Big Time Gaming productions with different max-win profiles. Alternating sessions can illustrate how theme and configuration choices affect perceived variance without changing the underlying reel mechanic.

Royal Mint Megaways has the higher RTP at 96.53%, compared with Bonanza Megaways at approximately 96% — a gap of roughly 0.53 percentage points. Both figures are listed as variable by Big Time Gaming, meaning the casino operator may deploy a lower configuration. Always check the in-game information panel before playing, as the displayed RTP reflects the version active on that specific platform. Over a long session, a 0.53-point difference has a measurable effect on theoretical return, so Royal Mint edges this metric.
No — both Bonanza Megaways and Royal Mint Megaways are classified as high volatility by Big Time Gaming. In practical terms this means both games are prone to extended losing runs punctuated by less frequent but potentially larger returns. Neither is the lower-risk option. The key difference in risk profile between the two is not volatility category but max-win ceiling: Royal Mint's 40,000× theoretical ceiling versus Bonanza's 26,000× suggests Royal Mint's distribution may skew slightly further into rare large outcomes, though this is not confirmed by published variance data.
Royal Mint Megaways carries a published max-win ceiling of 40,000× stake, while Bonanza Megaways is capped at 26,000× stake — a difference of 14,000× in theoretical maximum. It is important to note that max-win figures represent a mathematical ceiling under ideal conditions and are not a reflection of typical session outcomes. Both games are high-volatility products, and reaching figures near these ceilings would require an exceptional combination of cascade length, multiplier accumulation, and symbol alignment during the bonus round.
