Ra vs Osiris by Pragmatic Play turns a confrontation between Egyptian gods into a five-reel line game with expanding multiplier Wilds. You choose between Ra and Osiris modes before playing. The central event is a Wild contributing to a win: it expands vertically, then gains a longer-lasting role when Free Spins turn it into a walking Wild.
Quick take: A winning Wild can fill a reel, then walk left through the bonus while keeping its multiplier.
Theme and Gameplay
The Egyptian rivalry provides a reason for the opening choice. Osiris produces less frequent bonuses with higher average bonus wins, so the selection changes the balance of the feature chase rather than merely choosing a god's name.
Ordinary play uses a 5×5 grid and fifteen paylines. Three to five matching symbols pay on adjacent reels from the leftmost reel. The tall board leaves plenty of positions to scan, but a scattered collection of matching icons still needs to follow a paying line.
A Wild expands vertically when it contributes to a win and receives a multiplier. That qualifying win matters: the presence of a Wild by itself does not establish that it will expand.
Slot Features
Free Spins start with six turns and a minimum Wild multiplier. During the feature, expanding Wilds retain their multipliers, grant respins and walk one reel to the left until they leave the grid. Their position becomes part of the sequence, because a Wild's next location can affect which lines it helps complete.
This gives the feature continuity between reel stops. A multiplier-bearing Wild can remain involved as it crosses the board, rather than disappearing immediately after its first result.
Retriggers add another six spins and raise the minimum multiplier. The round can therefore develop through both the Wilds already moving across the reels and an improved starting value for subsequent Wilds.
Feature focus: Follow an expanded Wild's column as it moves left; its retained multiplier matters when that position helps form another paying line.
RTP and Win Potential
When multiple expanding Wilds are involved, their multipliers add together. Individual expanding-Wild multipliers can reach 1,000x. The useful distinction is addition: several multiplier labels do not mean their values are multiplied by one another, and a large Wild multiplier still depends on the line wins it affects.
My Thoughts On This Slot
The walking Wild is a strong fit for a taller line game. Its movement gives the next reel stop a specific point of interest, while retaining its multiplier makes that movement consequential. The requirement for a winning contribution also keeps the base-game expansion tied to an actual result.
The mode choice deserves attention from anyone mainly interested in reaching the bonus. Osiris's higher average bonus win comes with less frequent entries. Ra vs Osiris is most appealing when you enjoy following a powerful symbol through several changing positions.
Final Take: The Egyptian duel earns its place through multiplier Wilds that keep moving the bonus forward.
