Rival Gaming’s quest to make the best buffalo-themed slot continues with Blazin’ Buffalo Extreme. It’s a five-reel slot with some lovely sunset-tinged graphics and at least four big bonuses. You also have a shot at winning one of four fixed jackpots during the game.
The game features buffalo wilds that replace all regular symbols in the game. The buffalo becomes a sticky expanding wild when it appears on reel 3, however.
In addition, it triggers a free re-spin, during which all Hold & Win symbols remain in place. The process continues until no more Hold & Win symbols land on the screen.
You also trigger the Hold & Win bonus by landing six prize symbols on the screen. You win one of the first three jackpots – Mini, Minor, or Major – by re-triggering re-spins and filling the screen. The Grand Jackpot is won when you fill all 15 reel spots with the best-paying symbols.
Blazin’ Buffalo Extreme isn’t the most revolutionary online slot from Rival Gaming. It’s not even the most revolutionary Hold & Spin slot around.
However, the sticky expanding wild adds an extra element to the Hold & Spin mechanic. The 20,000x max prize, in addition to the four fixed jackpots, is also a major draw. Give the game a spin for free today and see what you think.
