Cash Tank Slot Overview
Cash Tank is a 5x3 military-money hybrid from Endorphina, running on 10 fixed paylines with a Win Both Ways mechanic. Released in February 2020, it leans on a single feature: Expanding Wilds that lock reels and trigger re-spins. Medium volatility, 96.01% RTP, no free spins round, no bonus buy. I see it as a grinder slot, not a big-win vehicle.
For serious players looking at this from a bankroll perspective, the max win sits somewhere between 1,000x and 1,500x depending on source. That ceiling is painfully low. Even at max bet of 200 EUR, the absolute top payout barely moves the needle for anyone used to chasing five-figure hits. I would not allocate meaningful bankroll here.
Symbols and Paytable
Dollar Sign leads the paytable at x100 for five-of-a-kind, followed by Gold Bar Bags at x50 and Money Stacks at x20. Four coloured gemstones fill the lower end, ranging from x15 down to x10 for a full line. Because wins pay both ways, you effectively double the number of chances per spin. Still, even with both-way pays, the top symbol at x100 is underwhelming compared to most modern slots I play.
Major Cash Tank is the only special symbol. It acts as wild, appears stacked on reels 2, 3 and 4 only, and substitutes for everything. No scatter exists. No separate bonus symbol. For a slot released in 2020, having a single special symbol feels thin. I expect more variety, especially when the volatility does not compensate with a high ceiling.

Expanding Wild Respins and Risk Game
Every time the Cash Tank wild lands on reel 2, 3 or 4, it expands to cover the entire reel. That reel locks, and the remaining reels re-spin once. If another wild hits on the re-spin, it also expands and locks, triggering another re-spin. Maximum is 3 consecutive re-spins with all three central reels fully wild. Best case scenario: three locked wild reels paying both ways across 10 lines. That is where the 1,000x theoretical max comes from.
After any base game win, you can enter the Risk Game, a standard card-pick gamble. Pick a card higher than the dealer's to double your win; fail and you lose everything from that round. Repeatable up to 10 times. RTP on the gamble drops to 84%, which is terrible EV. I never touch these; the house edge is brutal and it adds nothing to the slot's potential for disciplined players.

RTP, Volatility and Max Win Ceiling
RTP is 96.01% in base game, dropping to 84% if you use the Risk Game. Medium volatility with a max win capped around 1,000x to 1,500x. For context, most medium-volatility slots I consider worth playing offer at least 5,000x. Here, the ceiling is too low for this variance profile. You will sit through plenty of dead spins waiting for wilds to land on the centre reels, and when they do, the payout rarely justifies the wait.
Bet range runs from 0.10 to 200 EUR. With a proper bankroll at high stakes, the maths still does not work. Even hitting the theoretical max at 200 EUR gives you roughly 200,000 to 300,000 EUR. Sounds fine until you compare it to any modern volatile slot where 10,000x or higher is standard. I cannot recommend this for bonus hunting or high-roller sessions.
