Ra vs Osiris online slot game
Pragmatic Play is back with another god fight, and yeah, it looks like they found a formula that works. Ra vs Osiris drops in September 2026, and having played Zeus vs Hades, the drill is already familiar. Pick a side: Ra for high volatility, or Osiris if you want to slowly lose your mind with super-high volatility.

Ra vs Osiris Slot Theme and First Impressions
Pragmatic Play did a good job telling the two modes apart this time around. The god fight thing makes more sense here than it did in Zeus vs Typhon, where the screen felt like a mess. Walking into Ra mode, a desert vibe hits you with lots of red and gold. Pick Osiris, and you end up in a neon-green underworld, and each mode has its own music.

Ra vs Osiris Slot Bonus Features
On paper, this online slot looks loaded. You got mode selection, expanding wilds, a gamble wheel, special bets, and bonus buy. But after 400 spins, we spent most of our time in the base game.
Ra Mode vs Osiris Mode
Your first choice happens before you even hit spin, and it's there to actually change how the game plays:
- Ra Mode: Free spins come around more often, but the payouts are usually smaller. Theoretical RTP: 96.53%.
- Osiris Mode: Good luck triggering the bonus, but when it hits, it hits harder. Theoretical RTP: 96.54%.
We ran 200 spins in each mode. Ra gave us the bonus twice, while Osiris gave us zero. The RTP difference is basically nothing, so it comes down to whether you're willing to patiently sit through long dry spells or not.
Expanding Wilds with Multipliers
When a VS wild lands, it can stretch to fill the whole reel. But it only does that if it actually makes a win.
Once it expands, you get a little battle animation between Ra and Osiris, and each one pulls a random multiplier from x2 all the way up to x1000. Whoever wins, their multiplier gets slapped on every win on that line.
If more than one expanding wild helps with the same win, the multipliers add up.
This feature gave us most of our big wins during the session. The x1000 multiplier sounds amazing, and while it can technically happen, we mostly saw x2 to x10.
Free Spins & Gamble Wheel
There are 3, 4, or 5 Scatters needed to trigger 6 free spins. How many Scatters you started with decides the minimum wild multiplier for the round: x2, x4 or x8.
Before the round starts, you get a gamble wheel. You can risk the whole feature to try and bump that minimum multiplier up to x100. Land on red, though, and you lose the bonus.
Inside the feature, any expanding wilds stick around and move one reel to the left every spin, giving you respins until they walk off the screen. Their multiplier stays active the whole time.
Our experience with the gamble wheel was mixed. The first time we played it safe and walked away with 8.60x our bet. The second time we gambled and lost everything.
Special Bets (Super Spins)
If you want action right now and don't mind paying for it, Super Spins are there:
- Super Spin 1: Guarantees one expanding wild for x20 the bet (Ra) or x40 (Osiris).
- Super Spin 2: Guarantees a wild with a minimum x8 multiplier for x100 (Ra) or x200 (Osiris).
- Super Spin 3: Guarantees a wild with a minimum x100 multiplier for x1,000 (Ra) or x2,000 (Osiris).
We tried Super Spin 3 three times. Spent close to 3,000 EUR total, got back around 1,900 EUR. But paying for the wild doesn't mean it lands somewhere useful. In our opinion, that's a lot of risk for something that might end up in the wrong spot.
Bonus Buy
Don't feel like waiting for Scatters? There's a way to easily buy your way in:
- Free Spins: 100x the bet (Ra mode) or 250x (Osiris mode) for the regular feature.
- Super Free Spins: 250x the bet (Ra mode) or 500x (Osiris mode) for a feature with a minimum wild multiplier of x8.
The 100 EUR buy-in Ra mode paid out x191.30. But the 250 EUR Super Bonus buy-in only gave us x111.40 back. Just because you get a guaranteed multiplier doesn't mean the right symbols show up. We had a rough run, but someone else might do way better.
What to Expect When Playing
We put 200 spins through each mode at 1 EUR per spin. In Ra mode, free spins triggered twice, and the better of the two only paid 8.60x. In Osiris mode, we didn't see the bonus once in 200 spins.
The base game can chew through your balance. There are dry spells of 20 to 30 spins in Ra mode, and up to 50 in Osiris mode.
Funny enough, our biggest win of the entire session (319.20x) didn't come from a bonus at all. It was a base game spin where two expanding wilds with x10 and x7 multipliers landed on reels 2 and 3.
This game is for people with a thick bankroll and a lot of patience. You might be waiting a while for that one big hit.
Win Potential and Volatility
Ra vs Osiris advertises a max win of 25,000x the bet, a big jump from Zeus vs Hades at 15,000x and Zeus vs Typhon at 10,000x.
The RTP sits at 96.53% for Ra and 96.54% for Osiris, which is a hair above the 96% you usually see, so the house edge is slightly smaller over time.
The volatility is no joke. You will watch your balance drop through spin after spin with nothing to show for it, then one expanding wild might drop and put you back in the green.
We started our test with 100,000 EUR. After 200 spins in each mode at 1 EUR per spin, we finished with 100,211.70 EUR in Ra mode and 100,068.60 EUR in Osiris mode.
Mobile Performance
We gave it a quick spin on mobile using Chrome. Loads fast, no lag, touch controls work fine. The reels fit okay in portrait mode, but when a bunch of multipliers show up at once, the text gets hard to read. The bright red and green colors can be rough on your eyes on a small screen, so maybe turn your brightness down.
How Ra vs Osiris Compares - Other Slot Titles
We stacked it up against the two Greek-themed slots from the same developer.
| Game | Provider | Volatility | Max Win | Special Features |
|---|---|---|---|---|
| Ra vs Osiris | Pragmatic Play | High / Very high | 25,000x the bet | Mode selection, expanding wilds (up to x1000), free spins with walking wilds, gamble wheel and bonus buy. |
| Zeus vs Hades: Gods of War | Pragmatic Play | High | 15,000x the bet | Mode selection, expanding wilds (up to x100), free spins with sticky wilds and bonus buy. |
| Zeus vs Typhon | Pragmatic Play | High | 10,000x the bet | Split grid with pays both ways, random multipliers that combine, Super Free Spins with a progressive multiplier and bonus buy. |
If you're hunting the biggest possible payout, Ra vs Osiris wins with that massive prize cap and x1000 wild multipliers. If you want more action and more frequent wins, Zeus vs Typhon has 2,048 paylines and pays both ways, which might keep you happier.
Zeus vs Hades sits in the middle because it keeps the dual-mode setup, but the sticky wilds in free spins don't blow up as hard.
Verdict – Is Ra vs Osiris Slot Worth Playing?
The best thing about Ra vs Osiris is that the base game can hand you huge wins without ever touching the bonus round. The worst thing is how mean it can be (losing an entire free spins feature because the gamble wheel with +60% chance of winning landed on red? Ouch).
This slot is built for experienced high-volatility players who know what they're getting into. If you need regular wins to stay interested, you should probably look somewhere else.
