    BetsRank Verdict

    Hands-on testing by Alexandre Dubois — bonus tested, multiple sessions

    Big Time Gaming states on its own game page that Royal Mint combines Extra Chilli and Bonanza in a single slot, and for once the marketing line describes the architecture exactly: one horizontal bonus reel above the grid, a second below it, and both react along with it. Hence the name Triple Reaction. The detail that matters, noted by Big Win Board, is that Wilds appear only on those two bonus reels. All of the game's value therefore passes through four positions on top and four underneath, not through the main grid.

    The collection system is the best idea here. In the base game, three visible scatters open nothing — you need four to spell M-I-N-T — but they award a gold bar. On the fortieth bar, the next free spins round becomes the Heartstopper version, where the multiplier starts at x2 and climbs by 2 per reaction instead of 1. The game pays you for near misses instead of wasting them, which is rare.

    On the max win I cannot settle the question: our database holds 40,000x, SlotCatalog shows 41,300x, Big Win Board states 50,000x, and Big Time Gaming publishes no figure at all. At 96.48% RTP the game lands exactly on the studio's catalogue median of 96.49%. No gift, no swindle.

    Strengths

    • +Two genuine bonus reels rather than decoration: they carry the Wilds per Big Win Board
    • +The gold bar collection turns missed triggers into concrete progress
    • +Heartstopper doubles the multiplier at every step versus normal free spins
    • +Multiplier with no published ceiling during the feature
    • +96.48% RTP, in line with the Big Time Gaming catalogue median

    To consider

    • Three sources give three different max wins: 40,000x, 41,300x and 50,000x
    • Forty gold bars is a long target, reached only through near misses
    • Four scatters required for 12 spins, a harder threshold than the usual three
    • No bonus buy, so no shortcut into the feature
    • Big Time Gaming publishes neither a max win nor a multiplier ceiling

    About Royal Mint Megaways

    Royal Mint Megaways is a six-reel Megaways game released in February 2020, and one of the few titles where Big Time Gaming stacks two of its own earlier inventions on top of each other. The studio says so plainly on its official page: "Royal Mint combines Extra Chilli and Bonanza to bring twice the game play to a single one slot." In practice the main grid holds six reels showing between two and seven symbols each, which produces the classic Megaways ceiling of 117,649 ways to win — seven to the power of six. On top of that, per Big Win Board, sit two 1x4 bonus reels, one above and one below the main area. All three sets react together: that is what Big Time Gaming calls Triple Reaction.

    The reaction mechanic itself is standard for the studio: any symbol involved in a win is removed, new symbols drop to fill the gaps, and the sequence continues while fresh wins keep forming. What sets Royal Mint apart is that the two bonus reels are not decorative. Big Win Board notes that Wilds appear only there, on the top reel and the bottom one. A reaction that does not refresh those eight positions therefore delivers no new Wild.

    Free spins require four scatters spelling M-I-N-T, awarding 12 spins; each extra scatter adds 4 more, with SlotCatalog capping the feature at 20 spins. During the feature, a multiplier with no published ceiling starts at x1 and rises by 1 with every winning reaction. That is Bonanza's mechanic, unchanged.

    The game's real invention lies elsewhere, in Heartstopper. In the base game, every time three scatters land in view — a trigger missed by exactly one symbol — the player receives a gold bar. On the fortieth bar, the next free spins round is replaced by Heartstopper Enhanced Free Spins, where the multiplier no longer starts at x1 but at x2, and moves up in steps of 2 with each reaction. Across an identical reaction chain the multiplier therefore reaches exactly double: after eight reactions, x8 in the normal version against x16 in the Heartstopper version. Big Time Gaming sums it up on its own page as "Bonanza on Steroids". The system converts forty frustrations into a concrete asset, which very few machines bother to do.

    Now the numbers. RTP is 96.48%, meaning the house theoretically keeps €3.52 for every €100 wagered across a very large number of spins. The median of the 34 Big Time Gaming games in the BetsRank database comes out at 96.49%, so this title sits right on it, one hundredth apart. Volatility is rated high by SlotCatalog and by Big Win Board alike, which corrects the "very high" our record was carrying. Stakes run from €0.20 to €20 according to Big Win Board, a figure backed by an AskGamblers review that Big Time Gaming reproduces on its own page; SlotCatalog goes lower, down to €0.10.

    The max win is where the sources part company. Our database held 40,000x stake, SlotCatalog shows 41,300x, Big Win Board states 50,000x, and Big Time Gaming publishes no ceiling on its official page. We keep 40,000x for want of an arbiter, and flag the gap rather than hide it. In money, 40,000x is €8,000 at €0.20, €40,000 at €1 and €800,000 at the €20 maximum. For context, the median ceiling across the Big Time Gaming catalogue is 36,201x, so Royal Mint sits slightly above it whichever source you take. There is no bonus buy: free spins come from the scatters and nowhere else.

    Royal Mint Megaways FAQ

    What is Triple Reaction in Royal Mint Megaways?

    It is the simultaneous reaction of three areas: the six-reel main grid plus two 1x4 bonus reels placed above and below it.

    Winning symbols vanish everywhere at once and are replaced while new wins keep forming.

    Why do the two bonus reels matter so much?

    Because according to Big Win Board, Wilds appear only there.

    Eight positions in total, four on top and four underneath, concentrate most of the potential: a reaction that does not refresh them brings in no new Wild.

    How do you trigger the free spins?

    Four scatters spelling M-I-N-T award 12 free spins.

    Every scatter beyond the fourth adds 4 more spins, with SlotCatalog putting the feature ceiling at 20 spins in total.

    How does the free spins multiplier work?

    It starts at x1 and increases by 1 after every winning reaction, with no ceiling published by Big Time Gaming.

    The value of the feature therefore depends entirely on how long the reaction chains run.

    What are the base game gold bars for?

    Every time three scatters appear on screen in the base game — a trigger missed by a single symbol — the player receives one bar.

    These bars accumulate across sessions until they reach the threshold of 40.

    What happens on the fortieth gold bar?

    The next free spins round is replaced by Heartstopper Enhanced Free Spins.

    The multiplier starts at x2 instead of x1 and moves in steps of 2 with each reaction, doubling its value at every stage of the same chain.

    How much does Heartstopper really improve wins?

    Exactly double, on the multiplier.

    After eight consecutive reactions the normal version shows x8 while the Heartstopper version shows x16. Big Time Gaming describes the feature on its own page as "Bonanza on Steroids".

    What is the maximum win in Royal Mint Megaways?

    Sources disagree.

    The BetsRank database holds 40,000x stake, SlotCatalog shows 41,300x and Big Win Board states 50,000x. Big Time Gaming publishes no official ceiling, so we keep 40,000x while flagging the discrepancy.

    What is 40,000x worth in money?

    €8,000 at the €0.

    20 minimum, €40,000 at €1 and €800,000 at the €20 maximum. The median ceiling across the 34 Big Time Gaming games in the database is 36,201x, so this title sits slightly above it.

    What is the RTP and what does it cost?

    96.

    48%, meaning the house keeps €3. 52 per €100 wagered across a very large number of spins. That is exactly the Big Time Gaming catalogue median, measured at 96. 49% over the 34 games listed at BetsRank.

    Can you buy the free spins?

    No.

    Royal Mint Megaways offers no bonus buy: free spins come only from landing the four scatters, and the Heartstopper version only from accumulating the 40 gold bars.
