Ultimate Ink

Ultimate Ink, from veteran developer WMS, wraps a tattoo-parlour theme around a genuinely unusual betting structure. Rather than a single stake slider, players set their total wager using a combination of a Reel Cost button and a Bet Per Reel button, with the number of reels in play determined by the reel cost selected. It takes a minute or two to get your head around compared with a standard bet-per-spin format, and it's well worth reading through the paytable before diving in so the mechanics actually make sense once the reels start moving.

Visually, WMS has done a genuinely good job of building atmosphere here, setting the action inside a cosy tattoo parlour complete with a bluesy soundtrack. Symbols include 9 to Ace royals styled as traditional knuckle-letter tattoos, alongside classic tattoo motifs such as anchors, hearts, sailing ships, pin-up style figures, and skulls, with the skull as the top-paying symbol, worth 7.5x the stake for a five-of-a-kind combination and the only symbol that appears fully stacked on the reels. The wild appears exclusively on reels 2, 3, and 4, substituting for every symbol except the scatter.

The game runs on a 5-reel, 1,024-ways structure and includes a free spins bonus with generous retrigger potential, where wild multipliers can combine to boost winning combinations by up to 9x. Depending on how the operator has configured the game, there's also a chance to trigger randomly awarded progressive jackpots during play, adding an extra layer of unpredictability on top of the standard feature.

RTP is confirmed at 96.47%, a genuinely strong figure well above the typical market average, and volatility sits in the medium-to-high range, suggesting a reasonably balanced mix of regular smaller wins and the occasional bigger multiplier-boosted hit through the free spins. Stakes are flexible thanks to the reel-cost system, running from as little as 1p up to £100 per spin, giving both cautious and high-rolling players plenty of room.

Ultimate Ink stands out for its unusual betting mechanic as much as its tattoo theme, and the strong RTP makes it worth the small learning curve. Try the free demo at johnessyslots first to get comfortable with the Reel Cost system before deciding whether to switch to real-money play.
