Sun of Ra: Hold and Respin for the Grand Jackpot
Ra, king of the Egyptian gods, sits at the centre of this 50-line RubyPlay release, and every one of his features revolves around golden Coins. Six of them start Sunlight Spins, a single Wild can open the Jackpot Pick, and Scatters let you decide how your bonus plays out. With a 96.90% RTP, a 30.4% hit rate and a 4,200x ceiling, the Sun of Ra slot runs at UK casinos with stakes from £0.10 to £100 per spin.
UKGC Sites Running the Sun of Ra Slot
Each operator in this list stocks RubyPlay games and holds a UKGC licence. For Sun of Ra real money sessions, most of them accept a first deposit of £10, so you can sample the Sunlight Spins without a large bankroll.
Inside Ra’s Temple: How the Game Plays
RubyPlay frames the game around Ra as creator of everything, so the reels are packed with pharaohs, temple treasures and sun motifs rather than generic Egyptian filler. Our three-month engagement data places it in the top 15% of Egyptian-themed titles played in the UK. Animations kick in hardest on Coin landings, which makes sense, as Coins drive almost every big payout. The free version mirrors Sun of Ra real money play feature for feature, and in our sessions the game behaved the same at peak and off-peak hours. More Egyptian and sun-themed titles are compared on the Sun Slots UK homepage.
96.90% RTP and a 30.4% Hit Rate
At 96.90%, Ra pays back more than the 96.2% UK average, according to RubyPlay’s own figures. Volatility is listed as medium/high, yet the 30.4% hit frequency keeps the base game ticking, with roughly every third spin landing something. Most of the top-end potential sits in the bonus rounds, which is where the 4,200x maximum lives. How we check provider figures against our own sessions is explained on the About Us page.

Coins, Wilds and Scatters: Three Routes to a Bonus
Unlike most Egyptian slots, Ra gives you three separate doors into the bonus. Coins are the direct route: six or more lock in place and Sunlight Spins begin, respinning until no new Coins arrive or the 15th one fills the grid for the Grand. Wilds are the wildcard route, since any of them can launch the Jackpot Pick, where three matching coins hand you a guaranteed jackpot. Scatters are the choice route: three or more open Sunlight Choice, and you pick between Sunlight Spins and Free Games loaded with extra Wilds. In 3,000 test spins the Scatter route opened 23 times, and UK players tell us bonuses account for around 40% of their session wins. If you like coin-based respins, our Aztec Sun Hold and Win slot review covers a game built around the same idea.
- Sunlight Spins: 6+ Coins stick and respin. The 15th Coin completes the screen and wins the Grand.
- Jackpot Pick: triggered by any Wild. Match 3 coins to collect a guaranteed jackpot.
- Sunlight Choice: 3+ Scatters let you pick your bonus type.
- Free Games with Added Wilds: extra Wilds join the reels to build more line wins. A different take on free games, with expanding symbols, appears in Book of Sun Multichance.
- Wild: stands in for regular symbols on top of its Jackpot Pick role.
- Gamble Option: after a base game win, guess the card colour to double it. A wrong guess wipes the win. Use it with care, and see our Responsible Gaming page for tips on setting limits.
- Symbol Hierarchy: Cleopatra-themed icons, treasures and artifacts pay far more than the card suits.
Pharaohs, Treasures and Card Suits: The Paytable
At the top of the table stands the pharaoh, paying 500x your line bet for five in a row. Card suits do most of the everyday work, delivering about 65% of all wins in our tracking, while premium Egyptian icons account for the other 35%. Lines pay left to right across all 50, starting from reel one, with three matching symbols as the minimum. If the paytable in your casino differs from these values, tell us through our Contacts page.
Spinning for Ra on Your Phone
Sun of Ra slot works perfectly on smartphone and tablet devices through HTML5 technology. We tested the game on 12 different handsets ranging from 2019 models to current-generation devices, confirming compatibility with iOS 11+ and Android 7.0+. Battery consumption remained reasonable at 8% per hour of active play on mid-range devices. The interface automatically adjusts to portrait and horizontal orientations, with touch controls responding within 50 milliseconds. UK players using older devices from 2018 can still run Sun of Ra slots without significant performance degradation. Browser-based casinos, like the one in our VeryWell Casino review, run it without any download.

On a smaller screen the Coin counter during Sunlight Spins stays easy to read, so following the respins is just as simple when you play Sun of Ra online from a phone. The same goes for mobile-first lobbies such as Vegas Wild Casino.
Free Spins First, Real Stakes Later
Sun of Ra online in free mode is worth a few hundred spins before you deposit: it shows how often Coins cluster and whether you prefer Sunlight Spins or the Wild-heavy free games when Sunlight Choice appears. After that, any Sun of Ra casino from the list above runs the identical 96.90% version for real money. How we check those operators before listing them is explained on our License & Legality page.
