Page updated July 2026
Cash Tank marches players straight into a world of gold, jewels and high-rolling luxury, led by the cigar-smoking Major Cash Tank himself. Endorphina's 5x3, 10-line slot delivers a bold, military-styled money hunt where expanding Wilds and re-spins drive nearly all of the action.
The game leans into a flashy, military-luxury aesthetic, with the golden tank mascot dominating the reels surrounded by sparkling jewels, gold bars and money bags. It's a bold, polished presentation with real personality, positioning the Cash Tank symbol itself as the clear star of the show rather than a background element.
Cash Tank runs on a 5x3 grid with 10 fixed paylines that pay both ways — winning combinations count from left to right and right to left, effectively doubling the number of possible line hits compared to a standard one-directional slot. That structure alone gives the base game more consistent contact than its line count might suggest at first glance.
The Cash Tank symbol itself acts as the Wild, appearing only on reels two, three and four. When it lands, it expands to cover the entire reel and triggers a re-spin, with up to three total re-spins possible depending on how many Wilds appear across the sequence. This expanding Wild mechanic is the core of the game's win potential, capable of producing dramatic full-reel moments when multiple Wilds line up in succession.
Cash Tank carries a strong RTP of 96.0%, a genuinely competitive figure. Over a long run of spins, that's the theoretical percentage of every stake returned to players — a solid number for a slot built around one central, high-impact feature.
Rated medium volatility, Cash Tank strikes a reasonable balance — not the flat grind of a low-volatility title, nor the long dry spells of a high-volatility feature hunt. The both-ways payline structure keeps things ticking over at a fair pace, while the expanding Wild re-spins provide the punchier moments when they land.
After any win, players can choose to gamble their payout in a classic Risk Game — selecting one of four face-down cards and attempting to beat the dealer's card for a doubled win, with up to 10 attempts possible if things keep going your way. There's no bonus buy option here; every feature has to be triggered naturally through base-game spins, which keeps the game feeling a touch more traditional than many modern releases.
Stakes run from 0.1 up to 200 per spin, giving plenty of room to size a session around the expanding Wild feature's rhythm.
Cash Tank is a confident, punchy slot built almost entirely around its expanding Wild re-spin mechanic, backed by a strong 96.0% RTP and a fair medium-volatility pace. The lack of a bonus buy option means patience is required, but the both-ways paylines help keep the reels ticking over in the meantime.
