Ultra Ace

Ultra Ace (Microgaming) Review

Although Microgaming hasn't been in the spotlight much lately, it offers truly unusual and unique titles, and Ultra Ace is one of them. Released on January 14, 2026, this title offers a 5x4 grid and 1,024 betways where you benefit from cascading payouts. It uses a dynamic mathematical model with a high level of volatility and a decent RTP of 96.15% to compensate for it.

Before launching any round, you need to decide on the size of your bet, and here you can start with €0.20 per spin, increasing this value to €40, which is the maximum possible. The largest multiplier in Ultra Ace is x2,800. If you play at the maximum bet and take advantage of all the potential offered by the bonus features, you can win €112,000, which is still a nice prize.

So, the Cascading Reels engine is at the heart of this new release. This means that the symbols involved in the combo disappear, leaving room for new ones. Theoretically, this can lead to infinitely long chains of payouts within a single round, without having to pay a new bet. According to the paytable, you can form sequences of three or more identical icons located anywhere on the reels. But the main condition here is that identical symbols must be on adjacent reels.

Clearly inspired by video poker, this title offers mostly familiar card symbols. Most often, you will see card suits as the lowest-value icons. A little more rarely, the Jack, Queen, King, and Ace appear on the game grid, with the latter being the highest paying of the simple symbols. The arsenal of special icons includes two types of Wilds, as well as the Scatter and Golden Card, which are tied to the extras in this slot.

Ultra Ace Features

Just basic spins like in slots from years ago are not Microgaming's approach. So here you will find a multi-level bonus system with lots of unexpected twists. The top row of multipliers above the reels is also there for a reason, so the biggest prizes come from the bonus features.

Multiplier Trail

Considering the paytable, regular combos here do not promise huge payouts due to the rather low multipliers for most icons. But this feature saves the day as it adds extra multipliers that boost the winning potential. Each cascade triggers an additional multiplier from the x1, x2, x3, and x5 sequence. That is, if you are lucky enough to land 4 combos in a row in a single spin, the total prize will be multiplied by 5.

Golden Card

Occasionally, you'll see golden cards pop up on the middle reels. They're nothing special on their own. But once they land in a winning chain, the fun begins: the symbols immediately turn into wilds of either color (red or blue). This greatly increases the chances of cascades falling one after another.

Red Wilds

While blue Wilds are straightforward (they perform the usual substitution function), their red counterparts are something else entirely. If one lands on the game grid, it can randomly select 1 to 4 symbols on reels 2-5 and turn them into Wilds. But keep in mind that Red Wilds cannot transform Scatters and Blue Wilds.

Free Spins and Ultra Spins

Ultra Ace can reward you with 10 free spins, and for this, you need to land at least 3 Scatters in any position on the playing field. The advantage here is obvious, because you won't have to spend money on bets for the next 10 game rounds, but that's not all. In this mode, you will see an improved version of the Multiplier Trail with values doubled. This means that 4 consecutive cascades will bring you a x10 extra boost.

In some countries where the bonus purchase feature is available, you can also benefit from extreme multipliers (x5, x10, x20, and x50). This is essentially the coveted Ultra Mode, which can be purchased for x130 of your bet. If this is too expensive, you can purchase the regular FS bonus by increasing your bet 40 times, which is significantly cheaper.

Theme & Graphics

Launch this title and you will see card suits as well as figures such as J, Q, K, and A. Clearly hinting at video poker, Ultra Ace offers players a taste of the casino atmosphere with elements of luck and strategy. Visually, it is clear that the developers focused primarily on mechanics rather than graphics. Still, we are dealing with quite beautiful transitions and animations, especially during cascades and symbol transformations. As befits such giants as Microgaming, this game is optimized for mobile devices, so anyone can play it on the go.

Ultra Ace Free Play

If you don't want to risk your money, try the Ultra Ace demo version first. Here, you will be provided with virtual money to place bets. The only difference between the regular game is that you will not be able to withdraw your winnings, as they are credited in fake money. Otherwise, the Ultra Ace free play game is completely identical to the original title, so this is a good opportunity for you to get acquainted with all the bonus features without risking anything.

Pros & Cons of the Ultra Ace Slot

Our Verdict

If you've been looking for a slot machine that combines classic card aesthetics with powerful modern functionality, Ultra Ace is worth your attention. Here we have well-balanced mechanics where the Multiplier Trail is really useful, especially during free spins. Although the volatility is high and the multipliers for most symbols are quite low, these extra boosts really save the day. We played 200+ rounds of Ultra Ace and saw this for ourselves.

The gold cards that turn into Wilds are the highlight of this slot. But that's not all, because the Red Wilds can turn up to 4 random symbols on the grid into Wilds, which really helps to keep the cascades going. If you play cautiously with low stakes, you can achieve solid payouts. It's truly disappointing that the maximum multiplier here is limited to x2,800. So, this essentially pushes you to raise your bets if you want to win something substantial. But overall, we once again have a quality product from the industry giant, and you can see for yourself by testing Ultra Ace in demo mode right here on the SlotCatalog website.
