    BetsRank Verdict

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

    The auction in Beef Lightning is the best-built feature in this batch. You enter free spins with one cow and no bids; bonus coins raise one counter or the other, and the final prize is the product of the two. A product, not a sum. Twelve coins yielding six cows and six bid steps are therefore worth mechanically more than eleven cows and a single step, and the player has no say in how the split falls. That is one extra layer of variance stacked on top of what Megaways already delivers.

    Big Time Gaming publishes the medal scale, which few studios bother to do: three bronze medals pay 500x stake, four silver medals 2,500x, five gold trophies 25,000x. That last figure alone accounts for close to 45% of the 56,000x ceiling, which says plainly where the potential is concentrated.

    The Wilds deserve attention too: up to three of them can duplicate across their own reel and fill it completely, but only on reels 2 to 5. Reels 1 and 6 will never carry a Wild, which rules out a fully wild grid and explains the base game ceiling of 28,674x. Our record dated the release to September 2024; SlotCatalog puts it in June 2021, three years earlier.

    • No bonus buy: the auction comes only from the scatters

    About Beef Lightning Megaways

    Beef Lightning Megaways is a six-reel Megaways game from Big Time Gaming, released on 16 June 2021 as an exclusive and 30 June 2021 wide according to SlotCatalog — not September 2024 as our record claimed. The grid shows two to seven symbols per reel, giving the classic ceiling of 117,649 ways to win, seven to the power of six. On its official page the studio places the game "at the base of Mount Cashmore, home to the Bonanza mine": an explicit link back to its own best-known title.

    In the base game the mechanic rests on two elements. Reactions first: winning symbols are removed and replaced by new symbols falling from above, with the chain continuing while wins keep forming. Then the Wilds, whose rule is precise. Big Time Gaming states that at any time up to three Wilds can duplicate over their individual reels; when a duplication occurs, all symbols on that reel are replaced by Wilds. Those duplications can re-occur after reactions. Crucially, Wilds occur on reels 2 to 5 only. Reels 1 and 6 are excluded, which structurally rules out a fully wild grid and sheds light on the base game ceiling, set at 28,674x stake by SlotCatalog.

    Free spins trigger on three gold scatter bars carrying the letters M, O and O, which can land on any reel and in any position. Three scatters award 12 free spins, and each scatter beyond the third adds 4 more.

    That is when the cow auction begins, and it is the real feature of the game. The player starts with one cow and no bids. Every bonus coin revealed during free spins produces one of the six outcomes published by the studio: an increased number of cows, a bid that raises the current price, a retrigger awarding 10 free spins, a gold trophy, a silver medal or a bronze medal. At the end of the free spins, the number of cows is multiplied by the final bid and paid out as a bonus prize.

    That multiplicative structure is worth pausing on, because it changes the arithmetic. The result is not a sum of wins but a product of two counters, and a product rewards balance: for the same number of coins, six cows and six bid steps pay more than eleven cows and a single step. The player does not choose the split; it is drawn at random coin by coin. So this is an additional layer of variance, laid on top of the one the Megaways mechanic already provides.

    The three medal tiers run in parallel and Big Time Gaming publishes the exact scale: three bronze medals pay 500x stake, four silver medals 2,500x, five gold trophies 25,000x. That last amount alone represents close to 45% of the game's maximum win, which points unambiguously at where the potential sits.

    Now the figures. RTP is 96.43%, meaning the house keeps €3.57 per €100 wagered across a very large number of spins; that is slightly below the median of the 34 Big Time Gaming games in the BetsRank database, measured at 96.49%. Max win is 56,000x stake in the bonus and 28,674x in the base game, comfortably above the catalogue median of 36,201x. In money, 56,000x is €5,600 at €0.10, €56,000 at €1 and €560,000 at the €10 maximum. That €10 maximum is low for this studio, most of whose titles run to €20. SlotCatalog puts the minimum bet at €0.10 while AboutSlots lists €0.20: in practice the floor depends on the operator. Both sources rate volatility high, correcting the "very high" on our record. There is no bonus buy.

    Beef Lightning Megaways FAQ

    How does the Beef Lightning cow auction work?

    The player enters free spins with one cow and no bids.

    Bonus coins raise either the number of cows or the bid. At the end, the number of cows is multiplied by the final bid and paid out as the bonus prize.

    Why does the multiplicative structure change the arithmetic?

    Because a product rewards balance.

    For the same number of coins, six cows and six bid steps pay more than eleven cows and a single step. The player chooses nothing: the split is drawn at random, coin by coin.

    What can the bonus coins reveal?

    Six outcomes published by Big Time Gaming: an increased number of cows, a bid that raises the current price, a retrigger awarding 10 free spins, a gold trophy, a silver medal or a bronze medal.

    How much do the trophies and medals pay?

    The studio publishes the scale: three bronze medals pay 500x stake, four silver medals 2,500x and five gold trophies 25,000x.

    That last tier alone represents close to 45% of the game's ceiling.

    How are the free spins triggered?

    You need three gold scatter bars carrying the letters M, O and O, which can land on any reel and in any position.

    Three scatters award 12 free spins, with each additional scatter adding 4 more.

    How do the Wilds behave?

    At any time, up to three Wilds can duplicate over their own reel.

    When a duplication occurs, every symbol on that reel becomes a Wild, and the process can repeat after reactions.

    Why are reels 1 and 6 excluded from Wilds?

    That is the rule Big Time Gaming publishes: Wilds occur on reels 2 to 5 only.

    It structurally rules out a fully wild grid and sheds light on the base game ceiling, set at 28,674x stake.

    What is the maximum win in Beef Lightning Megaways?

    56,000x stake in the bonus and 28,674x in the base game according to SlotCatalog.

    That is comfortably above the Big Time Gaming catalogue median, measured at 36,201x across the 34 games in the BetsRank database.

    What is 56,000x worth in money?

    €5,600 at the €0.

    10 minimum, €56,000 at €1 and €560,000 at the €10 maximum. That maximum is low for Big Time Gaming, most of whose titles run up to €20 per spin.

    What is the RTP and what does it cost?

    96.

    43%, meaning the house keeps €3. 57 per €100 wagered across a very large number of spins. That is slightly below the 96. 49% median calculated across the 34 Big Time Gaming games listed at BetsRank.

    When did Beef Lightning Megaways actually launch?

    On 16 June 2021 as an exclusive, then 30 June 2021 wide according to SlotCatalog.

    Our record said September 2024, a three-year error that this update corrects.
