About this Slot
Ra vs Osiris is an ancient Egypt-themed slot by Pragmatic Play with an RTP of 96.53%, high volatility and a maximum win of 25,000x. The game runs across 5 reels and 15 paylines.
Expanding Wilds appear on any reel and stretch to full width when they form part of a winning combination. The multiplier attached to an Expanding Wild ranges from x2 to x1,000, with the value determined by which character-Ra or Osiris-is active in the chosen game mode.
Three scatters trigger 6 free spins with a minimum wild multiplier of x2. Four scatters activate 6 free spins with a minimum multiplier of x4, while five scatters award 6 free spins with a minimum multiplier of x8. Additional scatters landing during the free spins round grant 6 extra spins and can retrigger the bonus, with each retrigger raising the minimum multiplier up to a maximum of x1,000.
During free spins, Expanding Wilds transform into Walking Wilds that move one reel to the left on each respin until they vanish off the grid. A Gamble feature becomes available during free spins and can increase the minimum multiplier, though losing a gamble ends the round immediately.
The game offers a choice between Ra mode and Osiris mode at the start of play. Ra mode provides access to three special bets and two feature buy options. Osiris mode is available at double the cost and features altered minimum multiplier levels throughout the game.
