Ra vs Osiris

Ra vs Osiris: the short version

Pragmatic Play released Ra vs Osiris on 3 September 2026. Five reels, three rows, 20 fixed paylines, 96.50% RTP, medium volatility and a 5,000x maximum win. Stakes from €0.20 to €100.00 a spin.

Egyptian mythology is the most heavily worked theme in online slots, and a duel between two gods is a familiar premise. Pragmatic already runs Thunder vs Underworld and Angel Vs Sinner Eternal Battle on the same versus concept, both returning 98.04%. Ra vs Osiris returns a point and a half less than either, which is the first thing worth knowing about it.

Our rating: ★★★½☆ (3.5/5): solid, unremarkable maths on a familiar build. The 96.50% return is fine and the medium volatility makes it easy to plan around, but Pragmatic’s own back catalogue does the versus idea considerably better.

Key stats

How it plays

Twenty fixed lines on a 5×3 grid, one stake control, all lines live on every spin. Scarabs, the Eye of Horus and the two named deities populate the paytable against pyramids and temple stonework.

The medium volatility rating held up across a demo run at €0.20. Returns came in at a steady clip, most of them small, with the balance drifting slowly downward between the occasional line hit in the 10x to 25x range that pushed it back up. Over about 250 spins nothing approached the 5,000x ceiling, which is the expected outcome: on a medium-volatility 20-line slot the cap is a theoretical maximum, not a session target.

Pragmatic’s studio toolkit includes PowerNudge, a mechanic that nudges reels down after a winning combination to look for another, and the Drops & Wins tournament layer many operators enable across the catalogue. The game data does not confirm either for this title specifically, so read the info screen once you load it. Drops & Wins eligibility is set per operator and shifts between promotional periods.

Symbol clarity is good, which matters on a 15-position board where a busy background makes results harder to parse. It reads cleanly on a phone.

RTP, volatility and bankroll

96.50% return puts the theoretical house edge at 3.50%. Pragmatic’s 875 catalogued games average 96.41%, so this release lands 0.09 percentage points above the studio norm: technically better than average, practically indistinguishable.

The comparison that carries weight is against the studio’s versus-themed high-RTP titles. Thunder vs Underworld and Angel Vs Sinner Eternal Battle both return 98.04% and reach 15,000x. Against Ra vs Osiris that is 1.54 percentage points more return and triple the ceiling. On a €500 turnover the return difference is around €7.70 in your favour, and the higher cap gives the upside somewhere to go.

Medium volatility means the 96.50% comes back in a flat, frequent pattern. Bankroll requirements are modest and session length is predictable, which is the genuine advantage of this configuration over a high-volatility build at the same RTP.

Betting and bankroll maths

A 3.50% edge costs 3.5 cents per €1 staked. Three worked examples across a 500-spin session:

• €0.20 a spin: €100.00 staked, expected loss around €3.50. A €25 bankroll covers it comfortably.
• €1.00 a spin: €500.00 staked, expected loss around €17.50. Hold €120–€150 for variance.
• €5.00 a spin: €2,500.00 staked, expected loss around €87.50. Budget €600 upward.

The working rule for a medium-volatility 20-liner is 120 to 150 times your spin stake held in reserve for 500 spins. Below that, an ordinary dry stretch of 60 or 70 spins can end the session before the distribution has had a chance to even out.

At the €0.20 minimum a €10 deposit buys 50 spins. That is a thin sample. If deposit size is your constraint, the €0.10-minimum releases in this batch give you twice the playing time for the same outlay.

Where it sits in Pragmatic Play’s range

Pragmatic Play was founded in 2015, operates from Gibraltar under chief executive Julian Jarvis, and is licensed in more than 40 regulated jurisdictions. Its 875-game catalogue is among the largest in the industry and averages 96.41% return.

Ra vs Osiris is a template build. Its full specification (96.50% RTP, medium volatility, 5,000x cap, 5×3 grid, 20 fixed lines, €0.20 to €100.00 stakes) matches Eastern Fury and Hearts of Venus exactly, both released within the previous week. Lucky Drums 88 shares everything except its far smaller 888x cap. Gates of Olympus POP is the only release in that window to change format, moving to a 6×5 grid and high volatility. Choosing among the 5×3 four comes down to which artwork you prefer.
