Super Ace

Super Ace, developed by Jili Games, is a card-themed video slot built around a 1,024-payway grid and designed with mobile players front of mind — on desktop it even sits in a tall, phone-like column rather than a wide layout. Released in late 2021, every symbol on the reels is based on a playing card, giving the game a distinct crossover feel between video slots and traditional card games.

Theme and gameplay feel

You'll occasionally spot references to "Lucky Poker" in certain menus and paytable descriptions alongside the Super Ace name, reflecting how heavily the design borrows from card-game visual language. Golden cards, jokers and upgraded card variants all play a role in triggering features, and the mechanics lean on cascading wins, symbol transformations and multipliers layered on top of a free spins bonus. It's a clever bit of crossover appeal — the game looks and feels instantly familiar to anyone who's spent time around blackjack or video poker tables, even though it's built entirely as a slot.

Payouts are displayed as clean multiples of the total stake, which keeps the maths transparent. Aces sit at the top of the paytable, paying 2.5x the stake for five of a kind, with Kings at 2x, Queens at 1.5x and Jacks at 1x. The lower-paying symbols are suit-only card designs, with Spades and Hearts worth 0.5x and Diamonds and Clubs worth 0.25x for a full line.

What the RTP means for you

Super Ace returns a strong 97.0% to players over the long run, a genuinely above-average figure for the current slot market that works meaningfully in the player's favour over time.

Volatility, max win and stakes

The game carries a Low/Medium volatility rating, and while individual symbol payouts look modest at first glance, the 1,024-payway structure, stacked symbols and cascading multipliers help wins build up quickly during good runs. The maximum win sits at 1,500x the stake — not a headline-grabbing number, but supported by a steady feature loop. Stakes run from 0.50 up to 100 per spin.

Verdict

Super Ace's card-game crossover concept, strong 97% RTP and Low/Medium volatility profile make it an approachable, mobile-friendly pick for players who enjoy familiar card imagery blended with slot mechanics.
