Cash Pump

Cash Pump by Play’n GO is a video slot that features an unusual design: instead of a single screen of reels, it offers four independent grids of 3×3 reels each, with five fixed paylines per grid, totaling 20 paylines. The theme blends retro fruit machine aesthetics with an atmosphere set in vintage gas stations styled like Route 66 and a "stunt performer" character as the Wild symbol. The main feature is its Stacked Wilds function: if any of the central reels of a grid is completely filled with Wild symbols, that stack is cloned to the same positions on the other three grids. Additionally, these Wilds stack a random multiplier of up to 4× for the prizes of that spin. There are Scatter symbols that appear only on the central reels, and if a Scatter appears on each of the four grids at the same time, Free Spins are activated, initially granting seven free spins. During the free spins, each time four additional scatters are collected, five extra spins are added, and the multipliers set for the Stacked Wilds increase: the first goes up by +1, the second by +2, the third by +3, and the fourth by +4, with no maximum limit. The maximum prize reaches up to 10,000 times the bet. There is no option to directly purchase the bonus feature. The normal symbols include classics like bar, cherries, lemons, bananas, or the lucky seven, while the Wild substitutes for all except the scatters. The gameplay combines retro visual simplicity with modern mechanics of multipliers and synchronized special features.
