☀️ Choose Your God, Choose Your Volatility — Ra vs Osiris by Pragmatic Play
Two Egyptian deities. Two reels sets. Two completely different maths models. Ra vs Osiris is the explosive new Egyptian duel-themed video slot by Pragmatic Play, and its headline innovation happens before you even press spin: you personally choose the volatility of the game. Side with the falcon-headed sun god in The Kingdom of Ra for High volatility and more frequent Free Spins, or descend into The Underworld of Osiris for Very High volatility, rarer triggers and far bigger average bonus wins.
Played on a classic 5-reel, 4-row grid with 15 fixed paylines, Ra vs Osiris hides devastating power behind its traditional layout. The star mechanic is the VS Expanding Wild — a flaming red "VS" in Ra mode and a glowing green "VS" in Osiris mode — that fills an entire reel and grabs a random multiplier of up to 1000×. When several wilds join the same winning line, their multipliers add together. In the Free Spins round, every expanding wild also becomes a Walking Wild, marching one reel to the left on every respin while keeping its multiplier locked. Combine that with a gamble wheel that can push the minimum wild multiplier all the way to 100×, three Special Bet Super Spin modes, two Buy Feature options per profile and a maximum win of 25,000× the total bet, and you have one of Pragmatic Play's most aggressive Egyptian releases to date.

⚔️ The Eclipse War: When the Sun God Challenged the Lord of the Dead
For a thousand years the balance held: Ra sailed his solar barque across the daytime sky while Osiris ruled the silent green halls of the Duat below. Then the eclipse came. As the sun vanished behind a ring of emerald fire, Osiris raised his crook and claimed the daylight for the dead. Ra answered with his flaming mace, and the desert split in two — one half burning gold, the other glowing with underworld light. Jackals, cobras, crocodiles and scorpions chose their sides, and the ancient pyramids became a battlefield of light against shadow. Now the gods hand the final choice to you: stand in Ra's fire for swifter blessings, or walk Osiris's poison-green corridors where fortunes come rarely but strike like a thunderclap. Whichever god you serve, the eclipse will decide your reward.
📋 Symbol Guide & Paytable — Ra's Fire vs Osiris's Shadow
Every symbol in Ra vs Osiris by Pragmatic Play exists in two versions: a fiery red-gold Ra variant and a glowing green Osiris variant. The artwork changes with your chosen profile but the payouts are identical. All symbols pay from left to right on adjacent reels starting from the leftmost reel across the 15 fixed paylines.
All values below are expressed as multipliers of the total bet (×). For example, 5 matching low-pay card symbols return 1× your total bet, while 5 God symbols return 20×.

🔮 How to Play Ra vs Osiris — Complete Mechanics Guide
Ra vs Osiris by Pragmatic Play is built in layers: a profile choice that changes the maths, an expanding-wild multiplier engine in the base game, a walking-wild Free Spins round, an optional gamble ladder and, for impatient players, Special Bets and Buy Feature shortcuts. Here is exactly how each element works.
1. Step One — Choose Your Volatility Profile
Before your first spin you select one of two profiles from the Choose Volatility panel. The entire look, soundtrack and symbol art change to match — and, crucially, so does the maths.
🔴 RA MODE — The Kingdom of Ra (High)
- Volatility: High
- Theoretical RTP: 96.53%
- Higher chance to hit the Free Spins feature
- Lower average win per Free Spins round
- Cheaper feature access: Buy Free Spins from 100× total bet
- Best for: steadier sessions, more frequent bonus rounds
🟢 OSIRIS MODE — The Underworld (Very High)
- Volatility: Very High
- Theoretical RTP: 96.54%
- Lower chance to hit the Free Spins feature
- Higher average win per Free Spins round
- Premium feature access: Buy Free Spins from 200× total bet
- Best for: max-win hunters chasing the 25,000× cap
The RTP difference between profiles is negligible (0.01%), so the decision is purely about hit frequency versus payout size. Ra pays more often but smaller; Osiris tests your patience but delivers far heavier bonus rounds.
2. Expanding Wilds with Multipliers — The Core Engine
The flaming VS symbol is an Expanding Wild that can land on all five reels in both the base game and Free Spins. Whenever it hits and there would be any win after expansion, it stretches vertically to fill the whole reel and is awarded a random multiplier from this list:
2× · 3× · 4× · 5× · 6× · 7× · 8× · 9× · 10× · 15× · 20× · 25× · 50× · 100× · 250× · 500× · 1000×
- The multiplier applies to every winning combination the wild is part of.
- If more than one wild forms part of the same win, their multipliers add to each other — a 250× wild plus a 500× wild gives a combined 750× on that line.
- Because a full reel of wilds also pays as its own combination, a single high-multiplier expansion can convert a modest line into a four-figure multiple of the total bet.
Worked example: a 5-of-a-kind God line pays 20× total bet. Combine it with two expanding wilds carrying 100× and 250× and the additive multiplier becomes 350× — turning that single payline into 7,000× the total bet. This additive stacking is the true engine behind the 25,000× cap.
3. Free Spins Feature — 6 Spins, Walking Wilds & Respins
Hit 3, 4 or 5 Scatter symbols anywhere on the grid to trigger the Free Spins feature. You always receive 6 free spins, but the guaranteed minimum multiplier for every expanding wild in the round scales with the number of scatters:
| Scatters Hit | Free Spins Awarded | Minimum Wild Multiplier |
|---|---|---|
| 3 Scatters | 6 | 2× |
| 4 Scatters | 6 | 4× |
| 5 Scatters | 6 | 8× |
During the round, every expanding wild is also a Walking Wild. When one hits, it expands, takes a random multiplier, and the game then respins while the wild moves one reel to the left, keeping the same multiplier. It continues walking until it reaches reel 1 and exits the grid. If several walking wilds are on screen at once, respins continue until all of them have left the screen — which is how a single free spin can chain into a long, escalating sequence of paid respins. Special reels are used throughout the feature.
Retriggers
Hitting 3, 4 or 5 Scatters during the round awards 6 additional free spins and pushes the minimum multiplier 1, 2 or 3 positions higher on the multiplier list respectively. Once 1000× is reached as the minimum, further retriggers award only the extra spins.
4. The Gamble Wheel — Risk Your Spins for a Bigger Minimum
Before the Free Spins round begins, Ra vs Osiris offers a pure risk/reward decision. You may collect the current minimum multiplier and start playing, or gamble on a wheel:
- Win: the minimum wild multiplier moves up to the next value on the list (e.g. 8× → 9× → 10× → 15×…).
- Lose: all free spins are lost and the round ends immediately.
- The gamble can be repeated up to a maximum minimum multiplier of 100×.
- The exact win probability of each gamble step is displayed under the wheel, so every decision is fully transparent.
A Free Spins round entered with a guaranteed 100× minimum multiplier is where Ra vs Osiris becomes genuinely explosive — every walking wild carries at least 100×, and they add together across shared paylines.
🎯 Special Bets — Three Guaranteed-Wild Super Spins
Ra vs Osiris does not use a classic Ante Bet. Instead, the Special Bets panel offers three Super Spin modes that guarantee a wild on every single spin. Costs differ between profiles, and all figures below are expressed as multiples of the total bet.
| Mode | Cost — Ra | Cost — Osiris | Effect | RTP (Ra / Osiris) |
|---|---|---|---|---|
| Normal Play | 1× (standard) | 1× (standard) | Standard game, all features available | 96.53% / 96.54% |
| Super Spin 1 | 20× | 40× | 1 wild with a random multiplier guaranteed in a random position every spin, expanding if it creates a win · can randomly become a Walking Wild | 96.55% / 96.58% |
| Super Spin 2 | 100× | 200× | 1 guaranteed wild with a minimum 8× multiplier every spin · can become a Walking Wild with respins until it leaves through reel 1 | 96.55% / 96.54% |
| Super Spin 3 | 1000× | 2000× | 1 guaranteed wild with a minimum 100× multiplier every spin · can become a Walking Wild with full respin chain | 96.51% / 96.52% |
Super Spin 3 is effectively a base-game version of a maxed-out bonus round: every spin delivers a wild with a minimum 100× multiplier that can walk across the reels. It is the most direct base-game route toward the 25,000× ceiling — and the most demanding on a bankroll.
💰 Buy Feature — Skip Straight to the Free Spins
The Free Spins round can be triggered instantly from the base game via the Buy Feature menu. Two options are available in each profile, and prices are expressed as multiples of the total bet.
| Buy Option | Mode | Cost | What You Get | RTP |
|---|---|---|---|---|
| Free Spins | Ra | 100× | Standard Free Spins — walking wild minimum multiplier of 2×, 4× or 8× | 96.55% |
| Super Free Spins | Ra | 250× | All expanding walking wilds receive a minimum 8× multiplier | 96.51% |
| Free Spins | Osiris | 200× | Free Spins with walking wild minimum multiplier of 2×, 4× or 8× — higher average payout profile | 96.54% |
| Super Free Spins | Osiris | 500× | All expanding walking wilds receive a minimum 8× multiplier in the Very High volatility model | 96.52% |
Remember: after any purchase you still get the gamble wheel decision before the round starts. Buying Super Free Spins for a guaranteed 8× minimum and then gambling upward toward the 100× cap is the highest-ceiling line of play in the entire game — but a single losing wheel spin forfeits the whole round.
📊 RTP Comparison Table — Every Mode in Ra vs Osiris
| Configuration | Ra Mode RTP | Osiris Mode RTP |
|---|---|---|
| Normal Play (base game) | 96.53% | 96.54% |
| Super Spin 1 | 96.55% | 96.58% (highest) |
| Super Spin 2 | 96.55% | 96.54% |
| Super Spin 3 | 96.51% | 96.52% |
| Buy Free Spins | 96.55% | 96.54% |
| Buy Super Free Spins | 96.51% | 96.52% |
The entire RTP spread across all twelve configurations is just 0.07% (96.51%–96.58%), which means no setting meaningfully punishes the player. Your choice should be driven by volatility preference and session length, not by return percentage.
❓ Ra vs Osiris — Frequently Asked Questions
Who developed the Ra vs Osiris slot?
Ra vs Osiris was developed and published by Pragmatic Play. It is an Ancient Egypt themed video slot played on a 5-reel, 4-row grid with 15 fixed paylines, featuring two selectable volatility profiles (Ra and Osiris), expanding wilds with multipliers up to 1000×, walking wilds in Free Spins and a maximum win of 25,000× the total bet.
What is the RTP of Ra vs Osiris?
The theoretical RTP is 96.53% in Ra mode and 96.54% in Osiris mode. Special Bets and Buy Feature options shift it only marginally: Super Spin 1 is 96.55% (Ra) / 96.58% (Osiris), Super Spin 2 is 96.55% / 96.54%, Super Spin 3 is 96.51% / 96.52%, Buy Free Spins is 96.55% / 96.54% and Buy Super Free Spins is 96.51% / 96.52%.
What is the maximum win in Ra vs Osiris?
The maximum win is capped at 25,000× the total bet in both the base game and Free Spins. If a Free Spins round reaches 25,000× the round ends immediately, the capped win is awarded and all remaining free spins are forfeited.
What is the difference between Ra mode and Osiris mode?
In Ra mode (High volatility) the chance to hit the Free Spins feature is higher but the average Free Spins win is lower. In Osiris mode (Very High volatility) the trigger chance is lower but the average Free Spins win is significantly higher. The visuals, symbols and soundtrack also change to match the chosen god, and Buy Feature / Special Bet prices differ between profiles.
How do the expanding wild multipliers work?
When a VS expanding wild lands and there would be a win after expansion, it covers the entire reel and receives a random multiplier from 2×, 3×, 4×, 5×, 6×, 7×, 8×, 9×, 10×, 15×, 20×, 25×, 50×, 100×, 250×, 500× or 1000×. The multiplier applies to every winning combination it forms part of, and when more than one wild is in the same win their multipliers add to each other — for example 100× + 250× = 350× on that line.
What are Walking Wilds in Ra vs Osiris?
During the Free Spins feature (and in Super Spin 2 and Super Spin 3), every expanding wild is also a Walking Wild. After it expands and takes its multiplier, the game respins while the wild moves one reel to the left, keeping the same multiplier. Respins continue until all walking wilds have exited the grid through reel 1, which can chain a single free spin into a long sequence of paid respins.
How many free spins does Ra vs Osiris award?
Hitting 3, 4 or 5 Scatters awards 6 free spins with a guaranteed minimum wild multiplier of 2×, 4× or 8× respectively. Hitting 3, 4 or 5 Scatters again during the round retriggers the feature for 6 additional free spins and raises the minimum multiplier by 1, 2 or 3 positions on the multiplier list.
How does the gamble wheel work before Free Spins?
Before the Free Spins round starts you can either collect the current minimum wild multiplier and play, or gamble on a wheel. A win moves the minimum multiplier up one step on the list; a loss forfeits all free spins and ends the round. You can keep gambling up to a maximum minimum multiplier of 100×, and the win probability for each step is displayed under the wheel.
Does Ra vs Osiris have an Ante Bet?
There is no classic Ante Bet in Ra vs Osiris. Instead, Pragmatic Play offers the dual volatility profiles plus three Special Bet Super Spin modes that guarantee a wild on every spin: Super Spin 1 (20× total bet in Ra / 40× in Osiris), Super Spin 2 (100× / 200×) and Super Spin 3 (1000× / 2000×).
Can I buy the Free Spins feature in Ra vs Osiris?
Yes. In Ra mode, Free Spins cost 100× the total bet and Super Free Spins (minimum 8× wild multiplier) cost 250×. In Osiris mode, Free Spins cost 200× and Super Free Spins cost 500×. All four buy options keep an RTP between 96.51% and 96.55%.
What is the highest paying symbol in Ra vs Osiris?
The God symbol (Ra in Ra mode, Osiris in Osiris mode) and the WILD are the top payers, each awarding 20× the total bet for 5 of a kind, 10× for 4 and 2× for 3. Mid-tier animal symbols pay up to 10×, the cobra/scarab tier pays up to 5×, and the card symbols A, K, Q, J and 10 each pay 1× for a 5-of-a-kind line.
How volatile is Ra vs Osiris?
Volatility is player-selected: High in Ra mode and Very High in Osiris mode. High volatility games pay out less often on average but offer a greater chance of big wins in a short time span — expect extended dry spells punctuated by large multiplier-driven hits, especially in Osiris mode.
What are the minimum and maximum bets?
The minimum bet is $0.10 and the maximum bet is $500,000.00, subject to operator limits. When a Special Bet or Buy Feature is active, the cost of the round is your total bet multiplied by the relevant figure (from 20× up to 2000×).
Is there a free demo of Ra vs Osiris?
Yes — a free-play demo version of Ra vs Osiris by Pragmatic Play lets you test both Ra and Osiris modes, the walking wild Free Spins, the gamble wheel, all three Super Spins and both Buy Feature options with virtual credits, with no deposit or registration required.
Can I play Ra vs Osiris on mobile?
Yes. Ra vs Osiris is fully optimised for iOS and Android in both portrait and landscape. The 5×4 grid, the Choose Volatility panel, the Buy Feature and Special Bets menus and the walking wild respin animations all scale seamlessly to smartphones and tablets.
🏆 Final Verdict — Should You Fight for Ra or Kneel Before Osiris?
Ra vs Osiris by Pragmatic Play takes the studio's proven "gods at war" formula and applies it to Egyptian mythology with a genuinely meaningful twist: the player, not the developer, sets the volatility. That single decision reshapes hit frequency, bonus value and even the price of every Special Bet and Buy Feature — and it makes the game feel like two slots sharing one cabinet.
Mechanically, the expanding VS wild is the heart of the game. Multipliers reaching 1000× that add together across shared paylines mean a modest 20×-paying God line can detonate into thousands of times the total bet in a single frame. Layer the Walking Wild respin chains of the Free Spins round on top, and every triggered feature carries genuine threat of approaching the 25,000× cap.
The gamble wheel is the boldest design decision here. Being able to escalate the guaranteed minimum wild multiplier all the way to 100× — with the exact probability of each step shown on screen — turns the pre-bonus moment into a transparent, high-stakes psychological duel. It will be divisive: risk-averse players will collect early, while thrill-seekers will push until the wheel bites.
Add three Super Spin tiers with guaranteed wilds, four Buy Feature routes and a remarkably tight RTP band of 96.51%–96.58% across every configuration, and Ra vs Osiris stands out as one of the most customisable Egyptian slots on the market. The trade-off is clear: this is a demanding, high-variance game. The base game can be quiet for long stretches, and the low-pay symbols return only 1× for a 5-of-a-kind — all the value is concentrated in the wilds.
The verdict: if you enjoy volatility you can dial in yourself, multiplier maths with a genuine four-figure ceiling and features you can buy, boost or gamble, Ra vs Osiris is one of Pragmatic Play's most complete high-volatility packages. Casual players should start in Ra mode; max-win hunters belong in the green glow of Osiris mode. Try both in the free demo before committing — the two profiles genuinely play like different games.
