Ultra Ace

A second Ultra Ace, this one from Microgaming, arrives as a completely separate release with its own take on the card-and-cascade formula rather than any connection to other similarly-named titles on the market. This version runs on a 5-reel, 4-row grid with 1,024 ways to win, and it leans on a cascading reels system paired with an increasing multiplier ladder mechanic.

Wins are formed when three or more matching symbols land consecutively from left to right across adjacent reels. Once a win lands, the matching symbols clear from the grid and new ones cascade down to fill the gaps, and consecutive cascades within the same spin push a fixed multiplier ladder upward, boosting the value of any further wins in that same sequence. The multiplier resets once the chain of new winning combinations finally runs out, keeping each spin's outcome tied directly to how far the cascade run manages to extend.

Wild symbols substitute for standard paying icons to help complete combinations, while scatter symbols are responsible for triggering the free spins feature, where the multiplier ladder mechanic continues to build across consecutive cascades and additional scatters can retrigger extra spins on top of the initial award. There's also an upgraded "Ultra" mode referenced as part of the game's design, adding a further layer of feature potential for players who want to push the pace.

Visually, this Ultra Ace goes for a sleek casino card-game look, built around premium playing card visuals set against a dark backdrop with glowing reel highlights. Traditional card royals sit alongside stylised premium icons, and the cascading wins are backed up with smooth visual effects and confident sound design throughout.

RTP is confirmed at 96.15%, a solid figure above the market average, and volatility is rated high, matching a maximum win of 2,800x the stake, a noticeably more restrained ceiling than some cascading rivals but one that should come with a steadier feed of cascade-driven wins along the way given the high hit-rate style structure. Stakes run from 20p up to £40 per spin.

For players who enjoy the cascade-and-multiplier-ladder format but want a slightly different balance of risk and reward compared with other high-volatility card slots, this Ultra Ace is worth a look.
