Ra vs Osiris

Ra vs Osiris Slot Overview

Ra vs Osiris isn’t the first online slot where you can choose the game’s volatility, but forget about low-risk options, as you can choose between High or Very High options.

• Ra (High Volatility): Your chances of triggering the Free Spins are higher, but the average win is lower.
• Osiris (Very High Volatility): Free Spins don’t trigger as often, but the average win will be higher.

The game is otherwise about landing regular wins and ideally with the help of the expanding wilds with multipliers of up to 1,000x.

Triggering the Free Spins will give you the option to gamble for a higher multiplier or settle with what you have. Just be aware that a failed gamble makes you lose all the bonus spins.

The Free Spins are otherwise the highlight of this game as the expanding wilds trigger respins as long as they are in view. Landing several of them can create some very exciting situations.

Ra vs Osiris is scheduled for release in the UK on September 3, 2026, and the max win is 25,000x the bet.

CasinoWizard’s verdict: Ra vs Osiris ticks all the boxes & is exciting and entertaining (7.5 out of 10)

Ra vs Osiris isn’t unique in any way, but that doesn’t take away the fact that this is a brilliant online slot.

The theme is exciting, the graphics are impressive, and the VS symbols with expanding wilds with multipliers just work. Yes, you know these from Wanted Dead or a Wild and many other slots.

What’s great in this version is that when they appear in the Free Spins, they trigger respins and move one step to the left until gone. The respins continue as long as at least one expanding wild is in view.

This also seemed to be the key to accumulating big wins, as when you have several expanding wilds with high multipliers in favourable positions with a few respins left to enjoy, huge wins can happen.

The gambling feature before the free spins can be discussed at length, though, as these create a tempting but unnecessary/risky gambling element. Will you be disciplined enough to settle with the starting multiplier that you got, or will you risk it all for a higher one?

Ra vs Osiris is a great and entertaining online slot that reuses what has worked many times before. It’s still awesome, nevertheless.

Final verdict: 7.5 out of 10.

Ra vs Osiris is officially released on September 3, 2026.
