Congo Cash Slot by Pragmatic Play

Three jewels sit above reels 2, 3, and 4, visible at all times. They rotate every spin - sometimes showing a money value (anywhere from 5x to 200x your bet), sometimes a jackpot label (Minor at 25x, Major at 100x, Grand at 2,000x), and sometimes a free spins award between 8 and 100 spins. But the jewels just sit there until you trigger a collection. That takes a specific combination: a butterfly symbol on reel 1, another butterfly on reel 5, and at least one Congo Cash logo on the middle reels. Each Congo Cash symbol grabs the jewel directly above its reel, so landing all three middle positions filled means scooping up the entire board in one shot.

The jewel board has a persistence rule that changes how you approach bet sizing. Jewels are saved per bet level. Switch from $1 to $2 and you get a fresh set of random jewels. Go back to $1 and your old board is still there, exactly as you left it. So if you spot a Grand jackpot sitting above reel 3, you know it stays until either you collect it or change your bet. Free spins, when collected, run on a special reel set where at least one wild is guaranteed on the reel that triggered the bonus. The fixed jackpots aren't progressive - Grand always pays exactly 2,000x, no matter the bet level or how long you've been playing.

Dense tropical greens and golden ornamental borders wrap around the grid, with a silverback gorilla standing guard on the left next to the three jackpot meters. The symbol set is all Congo Basin wildlife - gorilla, leopard, a mandrill with that distinctive red-and-blue face, a ring-tailed lemur, and a bright green tree frog. The diamond wild only appears on reels 2 through 5, and the butterfly scatter is restricted to the outer edges (reels 1 and 5), which keeps collections feeling deliberate rather than random. Wild Streak Gaming built this one for Pragmatic's network, and they later expanded it into Congo Cash XL with a bigger grid.
