Review of Ra vs Osiris (New Demo Game)

Pragmatic Play dusts off its “vs” formula for a sequel nobody expected quite this soon — Ra vs Osiris, landing 3rd September 2026, follows directly in the footsteps of Zeus vs Hades Gods of War, BigWinBoard’s Slot of the Year 2023. Same core idea: pick your side before you spin. Choose Ra mode (highly volatile, red-lit visuals) or Osiris mode (very highly volatile, green-lit), and you can switch between them later without losing your place.

Pros

✅ Really fun to play if you like high-volatility slots.

✅ Two genuinely distinct play styles in one game -- Ra for frequent, smaller-swing action, Osiris for rarer but bigger payouts -- confirmed by the official description, not just cosmetic.

✅ Osiris pricing runs almost exactly double Ra's across every buy option, a clean and predictable pattern that makes budgeting for either mode straightforward.

✅ The VS Expanding Wild battle with multipliers up to 1,000x brings real drama to nearly every winning combination.

Cons

❌ Super Spin 1, 2, and 3 in both modes guarantee a Wild but can't trigger Free Spins -- an easy trap to fall into given how much the top tiers cost.

❌ The 25,000x max win cuts a Free Spins round short the moment it's hit, forfeiting any spins remaining in that round.

Introduction to Ra vs Osiris

The signature mechanic returns too — VS Expanding Wild symbols where two rival gods face off, and whoever wins decides the multiplier applied to that wild. But the numbers have gone up considerably: where Zeus vs Hades topped out at 100x per wild, Ra vs Osiris pushes that ceiling to 1,000x. Free Spins trigger off 3, 4, or 5 scatters for 6 spins with a starting minimum multiplier of 2x, 4x, or 8x, and this time the Expanding Wilds don’t just sit still — they become Walking Wilds, sliding one reel left with every respin until they walk off the grid entirely.

Here’s the part that stood out to me most: before Free Spins even start, you get a gamble option on a wheel to boost your starting multiplier all the way up to 100x — but lose the gamble, and you lose the entire Free Spins round outright. That’s a genuinely bold risk-reward moment sitting right at the start of the bonus, and my gut says this is exactly the kind of feature that’s going to appeal hard with high-volatility, high-limit players specifically — the kind of player who’d rather gamble away a mediocre round for a shot at a monster one than settle for a safe, average outcome.

Buy-in options scale with your chosen mode: three Special Bet tiers (20x/100x/1,000x in Ra, doubled to 40x/200x/2,000x in Osiris) and two Bonus Buy tiers (100x/250x in Ra, 200x/500x in Osiris). The max win sits at 25,000x — same as the beefed-up Zeus vs Hades Gods of War 250 rerelease, not the first version.

Early numbers point to a 96.53% RTP, High volatility, base hits around 1 in 6.76 spins, and Free Spins landing roughly every 205 spins. I’ve had a go on the demo already, and it’s genuinely fun — the light and sound design alone makes it feel like an event, not just another spin.

Winning tips -- which mode and option is actually worth it

Every RTP across both modes sits between 96.51% and 96.58% -- genuinely tight, so no option here costs you meaningful long-run value. The real decision is what kind of session you want, not which number is "best."

First, the trap that repeats in both modes: Super Spin 1, 2, and 3 all guarantee a Wild but none of them can trigger Free Spins. They're base-game multiplier tools, not bonus shortcuts -- easy to assume otherwise given how much they cost at the top tier.

Choose Ra if you want more frequent action. The official description confirms Ra triggers Free Spins more often, with smaller average wins -- and every buy-in option costs roughly half what the Osiris equivalent does. Good for longer sessions and steadier engagement.

Choose Osiris if you want fewer, bigger swings. Everything costs roughly double Ra's equivalent, which tracks with its lower natural trigger rate and bigger average payout when it does land. Super Spin 3 at 2,000x is a serious bankroll commitment in this mode specifically -- make sure you can genuinely absorb that cost per spin before turning it on.
