Ra vs Osiris Guide: Rules, Two Modes, Walking Wilds and Free Spins Gamble

By the CasinoDemo editorial team · Updated 2026-11-09 · How we review

Ra vs Osiris is a Pragmatic Play slot where you pick your god before you spin. The Kingdom of Ra is the high volatility profile, the Underworld of Osiris is marked very high, and the two change the look of the game, how often free spins land and what the bonus buys cost.

We played the demo at a $2 bet with no Super Spin active, read all ten rules pages and bought all four bonus options, two per mode. Every figure below comes from the rules screens or our own screenshots.

How Ra vs Osiris works

The game runs on five reels and five rows with 15 fixed paylines. Symbols pay left to right on adjacent reels starting from the leftmost reel, only the highest win is paid per line, and wins on several lines are added together.

At a $2 bet, 5 of the top god symbols (Ra in one mode, Osiris in the other) pay $40, which is 20x the bet, 4 pay $20 and 3 pay $4. The two animal premiums below it pay $20 for 5, the snakes and the scarab or scorpion pay $10 for 5, and every card symbol from A down to 10 pays $2 for 5, $1 for 4 and $0.20 for 3. The WILD substitutes for everything except the scatter, appears on all reels and pays the same as the top symbol.

The mode choice is on the right of the reels. The rules say plainly that in RA mode the free spins trigger more often but pay less on average, while in OSIRIS mode they trigger less often and pay more on average.

Expanding wilds with multipliers

The VS symbols are EXPANDING WILDS and can land on any reel. When one hits in the base game or free spins, and there would be a win after it expands, it fills the whole reel and takes a random multiplier: 2x, 3x, 4x, 5x, 6x, 7x, 8x, 9x, 10x, 15x, 20x, 25x, 50x, 100x, 250x, 500x or 1000x. The multiplier applies to every winning line the wild is part of, and when two or more wilds share a line their multipliers are added together, not multiplied. Our screenshots showed this on a single line: three A symbols plus a 15x wild paid $0.20 x 15 = $3.

Free spins, walking wilds and the gamble wheel

The sun scatter in Ra mode and the dark eclipse scatter in Osiris mode trigger the feature. Hit 3, 4 or 5 and you get 6 free spins with a minimum multiplier of 2x, 4x or 8x for the expanding wilds.

Before the round starts you can gamble that minimum. A wheel spins: a win moves the minimum to the next value on the list, a loss ends the round with no free spins at all. The chance is printed under the wheel at each step, and you can only gamble up to a 100x minimum. When we started at 8x the wheel showed 54.33% to reach 15x. In the Osiris round that started at 2x it showed 62.96% to reach 4x, and at 8x in Osiris it showed 52.13%.

During free spins every expanding wild also walks. It expands, gets its multiplier, then the game respins as the wild moves one reel to the left each time, keeping its multiplier, until it leaves through reel 1. With several on screen, the respins go on until all have left. Landing 3, 4 or 5 scatters again adds 6 spins and pushes the minimum up 1, 2 or 3 steps on the list. Once 1000x is the minimum, retriggers only add spins. Special reels are used during the feature.

Bonus buy options and our four demo buys

Each mode has its own Buy Feature menu with two options. In Ra mode, Free Spins cost 100x the base bet ($200 at $2) with an RTP of 96.55%, and Super Free Spins cost 250x ($500) with every walking wild getting at least 8x, RTP 96.51%. In Osiris mode, Free Spins cost 200x ($400) with a minimum of 2x, 4x or 8x, RTP 96.54%, and Super Free Spins cost 500x ($1,000) with an 8x minimum, RTP 96.52%.

Ra Free Spins, $200: five suns landed for an 8x start, and we took the gamble once and won, moving to a 15x minimum. That paid off. Stacked 15x and 25x walking wilds, and one at 50x, built a $1,380 total, 690x the base bet.

Ra Super Free Spins, $500: we collected the 8x. Pairs of 8x and 9x wilds walked across several times and the round paid $879, about 440x the bet.

Osiris Free Spins, $400: only three scatters, so a 2x start, which we kept. Wilds of 3x to 7x did the work and the round paid $440.40, about 220x the bet.

Osiris Super Free Spins, $1,000: 8x start, collected, with 9x wilds early. It paid $331.20, about 166x the bet and well under the price.

Those are four single rounds, not averages. Two of them returned less than their cost and the cheapest buy paid the most, which is a fair picture of how swingy this game is.

Super Spins (special bets)

Normal play uses a 10x bet multiplier. The Special Bets menu offers three Super Spin modes in each profile, and each one guarantees a wild with a random multiplier on every spin, which expands if there is at least one winning combination. Super Spin 1 can turn the expanding wild into a walking wild. Super Spin 2 guarantees a minimum x8 and Super Spin 3 a minimum x100, and in both the wild can randomly start walking and respin until it leaves through reel 1.

In Ra mode the multipliers are 200x, 1000x and 10000x, with RTPs of 96.55%, 96.55% and 96.51%. In Osiris mode they are 400x, 2000x and 20000x, with RTPs of 96.58%, 96.54% and 96.52%. At our $2 base bet the Osiris menu priced them at $80, $400 and $4,000 per spin. We did not play these modes.

RTP, max win, volatility and bet range

The theoretical RTP is 96.53% in Ra mode and 96.54% in Osiris mode. The rules page carries a high volatility badge, and the in-game switch labels Ra as High and Osiris as Very High. The maximum win is 25,000x the bet in base game and free spins; a free spins round that reaches it ends at once and the rest of the spins are forfeited. The game data puts the odds of the max win at 1 in 7,250,580 in Ra mode and 1 in 4,665,049 in Osiris mode. The rules screen lists a minimum bet of $0.10 and a maximum bet of $500,000.

Our verdict

Ra vs Osiris is really two slots sharing one set of rules, and the choice matters more than the theme. Ra gives you cheaper buys and more frequent free spins, Osiris doubles the buy prices in exchange for bigger average rounds, and the gamble wheel lets you trade free spins for a higher minimum multiplier at odds the game shows you. Walking wilds with added multipliers can snowball fast, as our 690x Ra round showed, but two of our four buys came back under cost. Use the demo to find which mode suits your nerves before anything else.
