Ultra Buffalo Hold and Win

Ultra Buffalo Hold and Win takes Booming Gaming's established buffalo-themed hold and win formula and scales it up with larger jackpots, expanding bonus grids, and extra upgrade mechanics layered on top of the classic formula. Set in a rugged Wild West canyon, the game leans on rich desert landscapes, wooden reel frames, and detailed animal symbols, with warm sunset colours giving the whole thing an authentic frontier feel.

The game plays out on a 5-reel, 3-row grid with 20 fixed paylines, with winning combinations formed by matching symbols left to right across active lines. Premium symbols include buffalo, eagles, cougars, and wolves, with the buffalo standing as the top payer and the only symbol capable of paying out on just two-of-a-kind combinations. Wild symbols substitute for all the regular paying icons to help fill in the gaps.

The real draw, though, is the Ultra Hold and Win feature, built around Coin symbols scattered across the reels. Landing enough of them, or triggering the bonus through other means, launches the feature, where locked symbols hold their position while expanding rows, glowing jackpot symbols, and special upgrade mechanics create genuine opportunities for a substantial payout. On top of that, a Buffalo Bonus Wheel can award jackpots and additional bonus features directly, a Wild Buffalo Herd mechanic can randomly transform symbols into standard or 2x wilds, and an Ultra Reel effect upgrades completed columns with multipliers and boosters during the respin round. Notably, there's no separate free spins mode here; all of the bonus depth is channelled through the Hold and Win system and its various add-ons.

RTP sits at 95.6%, close to the broader market average, and volatility is rated high, matching a maximum win of 5,000x the stake. Stakes run from 20p up to £100 per spin, giving a wide range to work with depending on how aggressively you want to chase the jackpot tiers.

For fans of the Hold and Win format who want more moving parts than a standard version offers, Ultra Buffalo Hold and Win delivers a genuinely expanded take with its Bonus Wheel, Wild Buffalo Herd, and Ultra Reel upgrades all stacked on top of the core respin mechanic.
