Mighty Buffalo Round ’em Up heads out onto the American frontier, where a shaggy bison stamped onto a polished gold coin is the face of the whole game. Greentube built it around one idea: gather coins during free games and watch the herd take over. Each spin costs between $0.10 and $100.00.
Theme and Gameplay
Wildlife of the plains fills the paytable. Bears, cougars, coyotes and hawks make up the mid-value animals, and the buffalo stands above them all. Gold dominates the artwork, from the embossed coin with its ring of stars to the heavy, polished horns, so the look is closer to a trophy cabinet than a dusty saloon.
Slot Features
Wilds can only land on reels 2, 3 and 4, with no more than one per reel. They replace everything apart from Scatters. Some arrive as 2x or 3x multiplier Wilds, boosting every win on that spin. When two or three of them join the same combination their values multiply together, so three 3x Wilds produce a 27x boost.
Landing 3, 4 or 5 Scatters during regular play awards 8, 15 or 20 free games. During the round, each Wild landing carries a 2x or 3x multiplier. Two Scatters during free games add 5 more, while 3, 4 or 5 add the same amounts as the original trigger.
Two kinds of coin can appear in free games. Gold Buffalo Coins fill an upgrade meter. At 4 coins the Bears turn into Mighty Buffalo symbols for the rest of the round, at 7 the Cougars follow, then Coyotes at 13 and Hawks at 15. Platinum Buffalo Coins fill a jackpot meter instead, and the highest level reached pays out when the round ends: 3 coins give 5x, 6 give 10x, 9 give the Mini at 25x, 12 the Minor at 100x, 14 the Major at 1,000x and 15 the Grand at 5,000x. Collecting either type of coin also drops a Buffalo symbol onto the reels.
RTP and Win Potential
With a 93.70% return and top-rated volatility, this slot keeps a larger edge than average and can go long stretches without much happening. Most of the value sits inside free games, where the coin meters and the 5,000x Grand live. Choose a bet size that can ride out those quiet patches.
My Thoughts On This Slot
I like how the two meters give a free games round a story. Rather than hoping for a random multiplier, you see the herd grow while the jackpot levels climb alongside it, and a long retrigger chain feeds both meters. The trade-off is the return figure. At 93.70%, the regular reels act like a toll paid on the road to the bonus, so fans of frequent small hits may find the wait tiring.
