Cash Pump offers an innovative and high-octane slot experience with its unique quad-reel layout, where players spin four individual 3x3 reel sets simultaneously. The game features classic slot symbols like fruits, BARs, and lucky 7s, alongside diamond wilds. A standout feature is the Wild Re-Spin, triggered when a stacked wild fills the middle reel of any grid, expanding to other grids for massive win potential. The Free Spins round introduces increasing multipliers, further amplifying the 'cash pumping' action across all four reel sets.
