Ra vs Osiris

Ra vs Osiris Slot Review

The first time a walking Wild moves across Ra vs Osiris and settles next to a stack of premium symbols, the choice between RA and OSIRIS suddenly feels like it matters more than the Egyptian theme it sits inside. Pragmatic Play have built something here that’s less about temple imagery and more about giving the player a genuine mathematical decision before each session: play RA for more frequent Free Spins with a lower average result, or commit to OSIRIS and accept fewer bonus triggers in exchange for stronger average potential. That’s a meaningful distinction in a crowded slot catalogue, and it lifts Ra vs Osiris well above the standard ancient-Egypt fare. The high volatility rating and a five-figure maximum win make the stakes clear from the outset, and the expanding multiplier Wild system that drives the bonus is the kind of mechanic that rewards patience with genuine build-up.

Base Game & Features

Ra vs Osiris runs on a 5×3 grid with 15 paylines. It’s a conventional layout that doesn’t attempt to distract from the mechanics, and that restraint is deliberate. The visual presentation shifts meaningfully depending on the active profile: RA runs warmer and brighter, with a golden palette, while OSIRIS leans into darker, more dramatic tones. The music and audio effects intensify noticeably whenever an expanding Wild appears or begins its movement across the grid.

Bets run from 0.10 to 250 per spin. The hit frequency is one win in every 6.76 spins, which gives the base game a reasonable level of activity between the bonus rounds that matter most. Free Spins land roughly once in every 204.76 spins organically.

Wild Symbol

The standard Wild symbol substitutes for all symbols except the Scatter and appears across all five reels. It acts as a conventional filler for incomplete payline combinations.

Expanding Wilds with Multiplier

Expanding Wild symbols also appear on all reels during the base game. When one lands and there would be a win after expansion, it stretches vertically to cover the entire reel and receives a random multiplier. The multiplier range runs from 2x up to 1000x, with intermediate steps at 3x, 4x, 5x, 6x, 7x, 8x, 9x, 10x, 15x, 20x, 25x, 50x, 100x, 250x and 500x. The multiplier applies to all winning combinations that the Wild contributes to. Crucially, when more than one Expanding Wild is part of the same combination, their multipliers add together rather than multiply against each other.

RA and OSIRIS Profile System

Before play begins, the player selects either the RA profile or the OSIRIS profile. In RA mode, Free Spins land more frequently but the average result per bonus is lower. In OSIRIS mode, Free Spins trigger less often but carry stronger average potential. The game’s visual presentation, audio and pricing all reflect the chosen profile. Switching profile changes not only the aesthetic but the mathematics and the cost structure throughout.

Scatter Symbols

Landing three, four or five Scatter symbols triggers the Free Spins round. The Scatter count at trigger sets the minimum multiplier floor for Expanding Wilds during the bonus: three scatters set the floor at 2x, four scatters at 4x and five scatters at 8x.

Special Bets – Super Spins

Both profiles offer three Super Spin tiers, each costing a multiple of the base stake and guaranteeing a modified Expanding Wild on that spin. Normal play costs 10x the base bet per spin. The Super Spin options are:

RA profile Super Spins:

• Super Spin 1 (20x bet) – guarantees one Expanding Wild per spin with a random multiplier. RTP 96.55%.
• Super Spin 2 (100x bet) – guarantees one Wild per spin with a minimum 8x multiplier; can become a Walking Wild with respins. RTP 96.55%.
• Super Spin 3 (1000x bet) – guarantees one Wild per spin with a minimum 100x multiplier; can become a Walking Wild with respins. RTP 96.51%.

OSIRIS profile Super Spins:

• Super Spin 1 (40x bet) – RTP 96.58%.
• Super Spin 2 (200x bet) – RTP 96.54%.
• Super Spin 3 (2000x bet) – RTP 96.52%.

Ra vs Osiris Bonus Features

Free Spins

The Free Spins round awards six free spins whenever the trigger lands (three, four or five Scatters). Special reels are in play during the bonus. The minimum multiplier floor for Expanding Wilds is set by the Scatter count at trigger, as described above.

During Free Spins, all Expanding Wild symbols also become Walking Wilds. When a Walking Wild lands and expands, a random multiplier is assigned and then a respin begins. On each respin, the Wild moves one position to the left, holding the same multiplier. When it reaches reel one and moves off the grid, no further respins are triggered for that symbol. If two or more Walking Wilds are active simultaneously, respins continue until all of them have left the grid.

Retriggering is possible: landing three, four or five Scatters during the Free Spins round awards six additional spins, and each retrigger advances the minimum multiplier floor by one, two or three steps on the value list respectively.

One cap applies: if the total win from the Free Spins round reaches 13x the bet, the round ends immediately.

Bonus Gamble Wheel

Before the Free Spins round begins, the player can use a Bonus Gamble wheel to try to improve the minimum multiplier floor. A spin of the wheel results in either a win – advancing the floor to the next higher value on the multiplier list – or a loss, which forfeits all six Free Spins and ends the round immediately. The gamble can be repeated up to a ceiling of 100x minimum multiplier, and the win probability for each attempt is displayed in-game under the wheel.

Super Free Spins

Super Free Spins is an enhanced version of the standard bonus where every Expanding Walking Wild is guaranteed a minimum multiplier of 8x. The higher floor means that every Wild that connects with a payline during the bonus carries meaningful value immediately. Super Free Spins is available as a direct bonus buy option in both profiles.

Buy Feature

The Buy Feature allows immediate access to the Free Spins or Super Free Spins round. Pricing reflects the profile chosen:

• RA Free Spins – 100x total bet (RTP 96.55%)
• RA Super Free Spins – 250x total bet; all Expanding Wilds receive a minimum 8x multiplier (RTP 96.51%)
• OSIRIS Free Spins – 200x total bet; all Expanding Walking Wilds receive the minimum multiplier based on scatter count (RTP 96.54%)
• OSIRIS Super Free Spins – 500x total bet; all Expanding Walking Wilds receive a minimum 8x multiplier (RTP 96.52%)

The pricing gap between profiles reinforces the underlying mathematical difference. OSIRIS purchases cost double their RA equivalents, reflecting the stronger average bonus potential that comes with the less frequent trigger rate. The profile choice affects costs throughout, not only during natural play.

Our Honest Verdict

Overall Rating: 7.8/10

Pragmatic Play’s Egyptian slot output has grown long and predictable, so Ra vs Osiris stands out by offering a decision that actually changes how the maths work rather than just how the symbols look. The base game has quiet stretches, but the Expanding Multiplier Wilds keep any spin capable of turning interesting. The Walking Wild system inside the bonus is where the game genuinely delivers: watching a Wild carry a 15x multiplier across the middle reels, then a second appear and overlap for a combined 23x on the same combination, is the kind of build-up that justifies the high volatility. Super Free Spins tightens the floor to 8x on every Wild, producing more consistent and immediate value than the standard round.

The RTP is 96.53% under the RA profile and 96.54% under OSIRIS in standard configuration, though operators can run lower settings (95.53% and 94.52% variants exist). The 25,000x maximum win is competitive for a game built around stacked Wild multipliers, though reaching it requires an exceptional Super Free Spins sequence where several Walking Wilds overlap at peak values. The Bonus Gamble wheel is the sharpest double-edged feature: losing the entire bonus on a failed spin is a genuinely punishing outcome, not just a mild setback. Players who’ve experienced that once tend to treat subsequent spins of the wheel with considerably more caution.

Comparisons to Wild West Gold (for the expanding multiplier Wild concept) and The Dog House Megaways (for the persistent multiplier Wild movement) are fair, but the profile-choice system gives Ra vs Osiris something distinctive. RA suits longer, natural sessions; OSIRIS works best as a shorter, more aggressive approach. That flexibility, combined with the bonus tension the Walking Wilds create, makes this worth returning to. Super Spin 3 at 1000x (RA) or 2000x (OSIRIS) is very difficult to justify for repeated play, but Super Spin 2 at 100x RA offers the 8x Wild floor without the extreme cost outlay. The profile system turns the Egyptian theme from familiar backdrop into a genuine point of difference.
