Ra vs Osiris

Ra vs Osiris Review

Ra vs Osiris is a spiritual successor to Pragmatic Play’s Zeus vs Hades: Gods of War slot. It builds on a similar formula while adding several changes to the feature set and math model. The game also swaps the Greek pantheon for an Egyptian one, as Ra, the god of the sun and life, takes on Osiris, ruler of the underworld.

Loading the game prompts players to select their preferred deity and volatility level. Ra vs Osiris is played in two modes: Ra’s Kingdom uses a High volatility model, while the Underworld of Osiris raises it to Very High. You can switch between the two at any point in the base game. The selected side also affects the visuals. The backdrop looks more or less the same in both modes, but Ra turns the screen red, while Osiris covers everything in green.

The symbol set changes as well. Ra sits at the top of his paytable, followed by lions, birds, cobras, and scarabs. Osiris becomes the top-paying symbol in the other mode, while Ra’s animal characters are substituted with wolves, crocodiles, pythons, and scorpions, respectively. Both versions also use card ranks as lower-value symbols, although those found in the Osiris mode are sort of “mummified”, wrapped in bandages to fit the underworld theme.

Rules-wise, the Ra vs Osiris slot machine follows the concept established in Zeus vs Hades: Gods of War. The game is played on a 5-reel layout featuring 3 rows and 15 fixed paylines. Symbols create wins from left to right, from 3OAK and more.

In true Pragmatic Play fashion, the betting range is wide. Stakes start at €0.10 at the lowest and reach €250 at the highest. That’s not counting the plethora of bonus bets and feature buy options that the developer has absolutely stuffed the Ra vs Osiris online slot with.

As mentioned above, the game has two volatility modes, with Osiris offering less frequent bonus rounds but with higher average wins. Still, on average, free spins tend to trigger once every 204.76 spins.

Regular wins, meanwhile, occur once every 6.76 spins, translating to a hit rate of roughly 14.8%. What's most impressive is the figure those wins can reach – up to 25,000x the stake. However, the likelihood isn't most friendly at 1 in 7,250,580.

In terms of RTP, the Ra vs Osiris slot game follows the standard Pragmatic Play trend and is supplied to casinos in three possible versions: 94.52%, 95.53%, and 96.53%. The exact setting depends on the operator, so it is best to check the game’s information panel before playing for real money.

Ra vs Osiris Bonus Features

The Ra vs Osiris slot revolves around Expanding Multiplier Wilds, which are the key to achieving the biggest wins in here. There is also a round of Free Spins where these Wilds start roaming across the reels and can trigger respins along the way.

Wild and Expanding Wild Symbols

There are two types of Wilds in the game, regular ones and special VS symbols. The standard Wild can appear on all reels and substitutes for every regular paying symbol.

The red and green VS icons are more interesting. Whenever they land, they expand to cover their reel entirely, and a battle of Ra and Osiris initiates. Each god shows a random multiplier value, and the winner’s number is applied to the expanding symbol. Possible multipliers range from 2x to a staggering 1,000x.

That value is then applied to every winning combination that includes that Wild symbol. If several of them contribute to the same win, their values are added together.

Free Spins

Landing 3 or more Scatter symbols activates the Ra vs Osiris free spins bonus round, awarding 6 initial spins. The number of triggering Scatters – 3, 4 or 5 – also sets the minimum multiplier available for Expanding Wilds during the round at 2x, 4x, or 8x, respectively.

Before the feature begins, you can either accept the current minimum multiplier or gamble for a higher one. The gamble uses a wheel that can move the minimum multiplier one step up the available value ladder, all the way to 100x. Losing, however, removes all awarded free spins and returns you to the base game with empty hands.

During the bonus, every Expanding Wild becomes a Walking Wild. Each one triggers a respin sequence after the expansion. It then moves one reel to the left with every following respin. After reaching reel 1, the Wild leaves the grid. If several Walking Wilds are active at once, respins continue until all of them leave the screen.

Landing another combination of Scatters retriggers the feature with 6 additional spins. If 3, 4, or 5 Scatter symbols hit simultaneously, they also raise the minimum Wild multiplier by 1, 2, or 3 positions on the list, respectively.

Super Spins & Bonus Buys

The first set of extra gambling options comes in the form of three bonus bets, called Super Spins in the Ra vs Osiris slot. Each guarantees one VS Wild in a random position on the next spin, but applies different multipliers. Also, they may turn into Walking Wilds randomly.

• Super Spin 1 – uses a randomly selected Wild multiplier and costs 20x the base bet in Ra mode or 40x in Osiris mode.
• Super Spin 2 – raises the guaranteed minimum multiplier to 8x, with the price increasing to 100x or 200x, respectively.
• Super Spin 3 – guarantees a multiplier of at least 100x and costs a massive 1,000x in Ra’s mode or 2,000x in the Osiris one.

There are also two ways to buy the Free Spins round directly. In Ra mode, the regular feature costs 100x the stake, while the Super option is priced at 250x. Osiris raises those figures to 200x and 500x.

The standard purchase starts with the Walking Wild minimum multiplier set at 2x, 4x, or 8x randomly. The Super free spins feature buy removes the lower possibilities and guarantees an 8x minimum multiplier from the beginning.

Pros And Cons Of Ra vs Osiris Online Slot

Final Thoughts

Ra vs Osiris is a nice addition to Pragmatic Play’s catalogue. I like that the developer did not simply put a new Egyptian skin on the existing Zeus vs Hades formula. The addition of Walking Wild respins makes the gameplay feel properly refreshed, and I also appreciate that they've raised the possible multiplier values up to 1,000x.

I do feel that the maximum win could have been higher, though. The 25,000x cap is on par with Zeus vs Hades: Gods of War 250, even though that version caps its multipliers at 250x and has no respins. On top of that, the probability of hitting the maximum payout is less than half as high in Ra vs Osiris.

All in all, it is a solid game and has enough new material to justify its place in Pragmatic’s collection. The two volatility modes give players some control over the math, while the roaming Wilds and multipliers create the kind of big-hit potential that should help Ra vs Osiris find its audience.
