Raging Rhino Rampage Buy Pass Slot by Light & Wonder

Reels that grow mid-spin are what this one is built around. At the start of any spin, two or more of the six columns can shoot up taller, reaching as high as six rows in the base game. Every extra row adds more matching positions, so the count of winning ways climbs hard, all the way toward 262,144 when the grid is at full stretch. The reels snap back to four high on the next spin, then the dice get rolled again. A second random touch can stuff those same reels with extra rhino symbols, which stack and line up easily across adjacent columns.

The look sells the setting straight. A heavy rhinoceros stands in golden, sun-bleached grassland to the left of the grid, an acacia tree in silhouette and a sky fading from blue down to pink and orange behind it. Symbols are wildlife - rhinos, crocodiles, cheetahs, eagles, gorillas - sat alongside gold-and-gem playing card royals on green reel strips, with a cut diamond as the scatter. Three jackpot meters sit across the top.

Three, four, five or six of those diamonds open the free games for 5, 8, 15 or 20 rounds, and 2 or more during the round top you back up. Before the spins start, a wheel runs first. It hands out extra free games, up to 50 more, plus a shot at one of three fixed jackpots, and each prize wedge it lands on flips to a START stop, so the wheel keeps turning until it finally hits one and ends. Inside the free games every win that leans on a wild gets boosted x2 or x3, and several wilds in the same combo apply their boosts one after another. Wilds only show on the middle four reels and stand in for everything but the diamond.

The savannah grind is optional, though. Pay 75x your bet for the Buy Pass and you drop straight into five free games with the reels able to reach eight rows instead of six. If that price stings, there's a cheaper gamble route: stake a smaller amount for a chance at triggering it, with better odds the more you put up.
