Unconventional, dynamic, and high-volatility. Our Cash Pump slot review focuses on this unique game by Play’n GO that might not have the best gimmicks, but certainly packs a fun twist or two to keep things more interesting than you would expect. This 12-reel slot game merges a classic fruit machine vibe with a vintage roadside gas station setting. As absurd as that sounds, it actually works. This unique title has four sets of 3x3 reels, each offering five paylines, for a total of 20 active paylines on every spin. With an RTP of 96.86% (on the default setting), high volatility, and a potential top prize of 10,000x your stake, it is definitely revved up for those who enjoy riskier spins. Cash Pump stands out for its unusual multi-reel approach—somewhat reminiscent of older WMS or Blueprint games—but punctuated by Play’n GO’s trademark sleek production values. If you like classic symbols, large multipliers, and fast-paced slot mechanics, you might just find yourself hooked on this high-octane trip along the highway.
Cash Pump’s key draw? Four separate 3x3 reel grids, each with five paylines for a grand total of 20 active lines. Not everybody is a big fan of split reels but this one feels different. Even though each grid is only three reels wide, collectively they function similarly to a conventional five-reel system. This means that they create multiple opportunities for hitting winning combinations with every spin.
The bet range is between £0.2 to £100 per spin and the highest RTP variant is a handsome 96.85%, which is notably higher than the industry average for a good slot game (96%). This is a high-volatility slot game, so expect massive but highly infrequent wins. The max potential payout of 10,000x sounds quite generous as it breaks away from the 5,000x norm of Play’n GO slots—more than enough to satisfy fans of riskier gameplay.

Cash Pump captures a retro gas station feel with bright reds, blues, and whites reminiscent of an American 1950s roadside vibe. Each of the four 3x3 reel sets is displayed on the face of a giant gas pump, set against a backdrop that calls to mind a desert highway or a cross-country road trip. You have guitar-driven rock tunes to complement the fast-paced spinning action for that high-octane atmosphere.
The symbols are a blend of classic fruit-machine visuals with 7s and BAR icons for higher pays. The star-spangled Wild (Driver) can substitute for all regular symbols, while the Scatter (red, white, and blue target) triggers the free spins round if it appears on the middle reel of every grid. Below is a quick look at how the base symbols pay when you match three of a kind on any single payline:
It is not a contemporary slot design from any angle. There are only six symbols and owing to the special arrangement of the reels, they only pay when you get three of them. Any other combination will not create wins.

This is a properly mobile-optimised, HTML5-based slot game by one of the leading game providers known for their user interfaces. As such, you can expect top-notch gameplay even though the scene is divided into four sub-grids with three reels and three rows each. The symbols and animations are crisp, the bet controls legible, and the game’s size lightweight for an excellent on-the-go experience using proprietary Play’n GO technology.
Cash Pump defies the usual five-reel approach with four compact reel sets, yet it remains refreshingly uncluttered. With just a handful of special mechanics, the slot still manages to keep gameplay tight and full of potential. I love how the stacked Wilds can copy themselves across all four grids, and the free spins bring some nice, rising multipliers.
Below are the three main bonus games or features on offer.
Whenever a full stack of Wild symbols lands on the middle reel of any single 3x3 grid in the base game, it replicates across the corresponding positions on the other three grids. A random multiplier between 1x and 4x is also applied to any resulting wins. It is a neat way to turn modest combinations into significant payouts, especially when multiple lines pay across all four sets simultaneously.
Land one red-white-and-blue scatter symbol on the centre reel of all four 3x3 grids during the same base spin and you will trigger the Free Spins round. You get 7 spins. During this round, you still have the chance of landing stacked Wilds in the middle reel which will replicate themselves on every grid. High volatility and the potential for sudden multi-line payouts are enough to keep the tension high, and even a single expanded Wild can swing fortunes drastically in your favour.
Once in the free spin bonus, each additional scatter that appears on all four grids simultaneously grants you extra free spins and boosts your active multipliers. You start with four base multipliers (1x, 2x, 3x, 4x) that apply to the stacked Wild duplication. Every retrigger not only gives five more free spins but also doubles these multipliers! The process can theoretically continue without limit, until you reach the slot’s 10,000x top potential. Few slot features match the excitement of watching your multiplier gauge climb sky-high, knowing one good cascade can tip your entire session into big-win territory.
I found the game quite interesting. It is not only about how it mixes two really random themes together (fruit machines and American highways), but more so about being a solid game despite having the quirkiness as its key attraction. With solid stats and strong gameplay, it is a game worth trying by anyone who is okay with the risk.
Rating: 7 (Good)
Cash Pump earns a solid 7 from me. The concept of four mini-reels might feel offbeat at first, but it offers a genuinely different experience without sacrificing strong payout potential. Often, “quirky” slots come saddled with low RTP or meagre max wins—here, we get an above-average RTP (96.86% default) and a 10,000x win cap, making it more than a novelty item. The stacked wild duplication and growing multipliers during free spins can produce some jaw-dropping results, provided you can handle the high volatility ride. All in all, Cash Pump scratches that itch for something creative and risky.
