Verdict: The Buffalo King Megaways slot is live in NJ, PA and MI, and its 96.52% top build returns more than most of the buffalo field. The 94.51% and 94.10% builds give much of that edge back, and the 5,000x ceiling is low next to the other buffalo Megaways titles.
How the Buffalo King Megaways reels and top reel work
The Buffalo King Megaways slot runs six reels that each show between two and seven symbols per spin, plus a horizontal top reel of four symbols sitting over reels two to five. The number of symbols on each reel changes every spin, and so does the number of ways, up to a maximum of 200,704. Pragmatic Play released it in 2021 under licence from Big Time Gaming, the studio that owns the Megaways mechanic. Release dates differ by a couple of weeks across sources (Slotcatalog has April 16, casinos.com April 29), but all agree on 2021.
It is the second of three Buffalo King titles. The original Buffalo King from 2019 used a fixed 6x4 grid with 4,096 ways, and Buffalo King Untamed Megaways followed in 2024. The Megaways version is the one most players know, and it sits first in the ranked list of buffalo slots.
The wild lands on reels two to five by way of the top reel. Reels one and six never show it, so a winning way still has to open on the left with a regular symbol.
Volatility is high. Bigwinboard rates it 5 out of 5, and Pragmatic Play’s page gives no rating of its own. Expect quiet stretches broken up by tumble chains, with the free spins carrying most of the value.
Tumbles, the Ante Bet and the 100x buy
Every win triggers a tumble. Winning symbols disappear, the symbols above drop into the gaps and new ones fall in from the top, and the sequence continues as long as new wins form. One paid spin can pay several times. This is the main reason the base game feels busier than the original Buffalo King, even though most single wins are still small.
Two options change the cost of a spin. The Ante Bet adds 25% to the stake and doubles the chance of landing free spins. The feature buy jumps straight into the free spins for 100x the total bet, where the jurisdiction allows it. Some markets restrict bonus buys, so the button is not shown in every lobby.
Whether the Ante Bet is worth it is a fair question with no published answer, since no source used here gives an RTP for Ante Bet play. What is certain is that it raises the cost of every spin by a quarter, which adds up quickly over a long session. For a player who comes for the free spins and has the bankroll for a high-volatility game, it is the more sensible setting. On a small budget, more spins at the base stake go further.
Bets run from 0.20 to 125 on the default range Bigwinboard lists. US casinos set their own caps, and HighStakesGuide reports maximums between $100 and $200 at operators in New Jersey, Pennsylvania and Michigan.
Free spins: where the adding multipliers come from
Four scatters award 12 free spins, five award 17 and six award 22. On top of the spins, the trigger pays 5x, 20x or 100x the bet for four, five or six scatters. Landing three or more scatters during the round adds five more spins, and there is no limit on retriggers.
The wilds carry the round. In free spins, each wild comes with a x2, x3 or x5 multiplier. When more than one wild helps form a win during a tumble sequence, the values are added together (a x2 and a x5 make x7), and the total keeps building as long as the tumbles continue. When the sequence on that free spin ends, the multiplier resets.
That is a softer system than the original Buffalo King, where wild multipliers in one win are multiplied together. The trade is visible in the maximum win: Bigwinboard lists 5,000x for the Buffalo King Megaways slot, against the 93,750x reviewers quote for the 2019 game. The Megaways version pays more often during free spins and peaks lower.
The free spins awards of 12, 17 and 22 step up by five for each extra scatter, the same five spins a retrigger adds inside the round. Pragmatic Play kept the arithmetic simple, and it makes the round easy to track while it runs.
Two RTP builds, plus a third reported in New Jersey and Michigan
Pragmatic Play’s provider page lists an RTP of 96.52%. Bigwinboard and Slotcatalog also list a 94.51% version, and the operator decides which build to offer. HighStakesGuide also reports a 94.10% build at Hard Rock Bet in New Jersey and Michigan. That figure does not appear in the provider or reviewer RTP lists, so it should be treated as a lobby-specific report.
At 96.52% the game returns more than most of the buffalo field, including Aristocrat’s original Buffalo slot machine at 94.72% online. At 94.10% it drops below that.
Comparing the RTP with the sequel and the predecessor is straightforward: the original Buffalo King lists 96.06% on its provider page and Buffalo King Untamed Megaways lists 96.02%. Of the three, the Megaways game has the highest top build.
Trying the Buffalo King Megaways demo before real money
The Buffalo King Megaways demo is worth a session for two reasons. The tumbles and the top reel take a few dozen spins to read, and the adding wild multipliers in free spins behave differently from the multiplying wilds of the original, which is easy to misjudge from a description.
The demo will not show the RTP build of a real-money casino. Use the demo to learn the mechanics and to test whether the Ante Bet feels worth the extra cost, then check the help screen once you are in a licensed lobby.
The demo also answers a question the rules sheet leaves open: how the game feels at the stake you plan to use. A few sessions in the Buffalo King Megaways demo at a set bet show how long the gaps between free spins tend to run, how often a tumble chain reaches three or four steps, and whether the 25% Ante Bet surcharge feels like a reasonable price. None of that predicts a real-money result, but it does show whether a high-volatility Megaways game suits the way you like to play before any money is involved.
What changed from the 2019 Buffalo King
Pragmatic Play rebuilt almost everything except the name and the premise. The fixed six-by-four grid of the original became six reels of two to seven symbols plus the top reel, and 4,096 ways became up to 200,704. Tumbles arrived, and so did two options the first game never had, the Ante Bet and the 100x feature buy.
The free spins changed the most. The original awards 8, 15, 25 or 100 spins and multiplies its wild multipliers together within a win, which is how reviewers reach a theoretical 93,750x. The Buffalo King Megaways slot awards 12, 17 or 22 spins, pays a scatter prize on the trigger and adds its wild multipliers across a tumble sequence. Wins in the round come more steadily, and the ceiling drops to 5,000x.
The RTP moved up at the top end, from 96.06% to 96.52%, and both games have lower builds. Availability is the practical difference for US readers. The original is not confirmed at US online casinos, while the Megaways version is in licensed lobbies in three states. The Buffalo King vs Buffalo King Megaways comparison covers the rest.
Reading a free spins round as it runs
Two numbers matter during the round: the spins left and the multiplier on the current tumble chain. Because the multiplier resets at the end of each free spin, a round with many short spins can finish modestly even after a big trigger. The results that stand out come from one long tumble chain with two or three wilds feeding it. A retrigger is worth five spins each time, and since there is no limit, a lucky round can run far past its starting count. Nothing carries over between spins except the count itself.
What this review weighs against the Megaways rivals
The game shares its 200,704-way layout with BGaming’s Savage Buffalo Spirit Megaways, which is offshore-only and not confirmed at US online casinos. Its more direct US rival is Almighty Buffalo Megaways, White Hat Studios’ US edition of Blueprint’s Buffalo Rising Megaways, with up to 117,649 ways and a free spins multiplier that rises after every cascade. The Buffalo King Megaways vs Almighty Buffalo Megaways comparison goes through both.
Blueprint’s own version, Buffalo Rising Megaways, is the other obvious match, and the Buffalo King Megaways vs Buffalo Rising Megaways page sets the two side by side. Buffalo Rising offers a choice of free spins modes and an unlimited multiplier; the Pragmatic game has the more fixed, predictable round with a defined scatter payout.
In this review’s reading, it wins on balance. It has the highest top RTP among the Pragmatic buffalo titles, a clear free spins structure, an Ante Bet and a buy for players who want them, and confirmed real-money availability in three states. The weak points are the 5,000x ceiling, which is low next to the other buffalo Megaways titles, and the lower RTP builds that some casinos run.
Where Buffalo King Megaways is live: NJ, PA and MI
Licensed online casinos in New Jersey, Pennsylvania and Michigan carry the game. Operator lists tracked by HighStakesGuide include Caesars Palace Online, Golden Nugget, BetMGM, Borgata and Hard Rock Bet, with BetMGM’s US blog also reviewing the title. In Pennsylvania the listed carriers are Caesars, BetMGM and Borgata. These lists come from a third-party tracker checked in April and July 2026, not from the operators themselves, so a quick look in the state lobby is the final word. Lobby search under the full title, with Pragmatic Play as the provider, is the fastest route. If the game is missing in one state, the same brand’s lobby in another state may still carry it, since each state runs its own game approvals.
The state pages for Pennsylvania and Michigan list the licensed casinos in each market. Real-money play is limited to adults 21 and over, and the maximum stake at US operators falls between $100 and $200 per spin depending on the casino.
