Ra vs Osiris online slot review
Pragmatic Play returns to its god-versus-god format with Ra vs Osiris. The game arrives in September 2026, and its structure may feel familiar to anyone who has played Zeus vs Hades. In Evan Carrington’s GCCans review, Ra is presented as the high-volatility choice, while Osiris is described as the option for players prepared for even more severe swings.

Ra vs Osiris slot theme and first impressions
Pragmatic Play makes the two modes feel clearly distinct this time. The god-battle concept works more cleanly here than in Zeus vs Typhon, where the presentation could feel cluttered. Enter Ra mode and the screen takes on a red-and-gold desert atmosphere; choose Osiris and it shifts to a neon-green underworld. Each mode also has its own music.

Ra vs Osiris slot bonus features
On paper, Ra vs Osiris offers plenty: mode selection, expanding wilds, a gamble wheel, special bets and Bonus Buy. However, the review reports spending most of its 400 spins in the base game rather than in the feature rounds.
Ra mode vs Osiris mode
The initial choice comes before the first spin and genuinely changes the way the game behaves:
- Ra Mode: Free spins appear more often, although the usual payouts are lower. Theoretical RTP: 96.53%.
- Osiris Mode: The bonus may be difficult to trigger, but its hits can be stronger when it arrives. Theoretical RTP: 96.54%.
The review records 200 spins in each mode: Ra produced the bonus twice, while Osiris produced zero. Since the RTP difference is effectively negligible, the choice is really between tolerating long dry spells and taking the more punishing route.
Expanding wilds with multipliers
A VS wild can expand until it covers an entire reel, but only when that expansion contributes to a winning combination.
After expansion, a short Ra-and-Osiris battle animation plays. Each god receives a random multiplier ranging from x2 to x1000, and the winning god’s multiplier applies to every win on that line.
When more than one expanding wild contributes to the same win, their multipliers are added together.
The review says this feature produced most of the session’s larger wins. Although x1000 sounds spectacular and can technically occur, the observed results were mostly in the x2 to x10 range.
Free spins & gamble wheel
Landing 3, 4, or 5 Scatters triggers 6 free spins. The number of Scatters collected determines the round’s minimum wild multiplier: x2, x4 or x8.
A gamble wheel appears before the free spins begin. You can risk the entire feature to raise that minimum multiplier as high as x100, but landing on red forfeits the bonus.
During the feature, expanding wilds remain in place and move one reel to the left after every spin. They create respins until they leave the screen, with their multiplier staying active throughout.
The review’s gamble-wheel results were mixed. On the first attempt, it was played safely and returned 8.60x the bet; on the second, the gamble was taken and the whole feature was lost.
Special bets (Super Spins)
Players who want an immediate feature and accept the extra cost can choose one of the Super Spins:
- Super Spin 1: Guarantees one expanding wild for x20 the bet in Ra or x40 in Osiris.
- Super Spin 2: Guarantees a wild with a minimum x8 multiplier for x100 in Ra or x200 in Osiris.
- Super Spin 3: Guarantees a wild with a minimum x100 multiplier for x1,000 in Ra or x2,000 in Osiris.
The review says Super Spin 3 was tried three times, with close to 3,000 EUR spent in total and around 1,900 EUR returned. Paying for the wild does not ensure that it lands in a useful position, so the reviewer considered this a substantial risk for an uncertain result.
Bonus Buy
For players unwilling to wait for Scatters, the game also offers a direct route into the feature:
- Free Spins: 100x the bet in Ra mode or 250x in Osiris mode for the standard feature.
- Super Free Spins: 250x the bet in Ra mode or 500x in Osiris mode for a feature with a minimum wild multiplier of x8.
The reported 100 EUR Ra-mode purchase returned x191.30, while the 250 EUR Super Bonus purchase returned only x111.40. A guaranteed multiplier does not guarantee the right symbols, and the review’s poor result could differ from another player’s session.
What to expect when playing
The review put 200 spins through each mode at 1 EUR per spin. Free spins triggered twice in Ra mode, with the better round paying 8.60x; in Osiris mode, the bonus did not appear once in 200 spins.
The base game can consume a balance quickly. The review encountered Ra-mode dry spells of 20 to 30 spins and Osiris stretches of up to 50.
Interestingly, the session’s largest win, 319.20x, came from the base game rather than a bonus. It resulted from two expanding wilds carrying x10 and x7 multipliers on reels 2 and 3.
This is a slot for players with a substantial bankroll and plenty of patience. The review suggests that the wait for a major hit can be lengthy.
Win potential and volatility
Ra vs Osiris lists a maximum win of 25,000x the bet, exceeding Zeus vs Hades at 15,000x and Zeus vs Typhon at 10,000x.
The stated RTP is 96.53% for Ra and 96.54% for Osiris, slightly above the 96% figure often cited for comparable slots. Over time, that implies a somewhat smaller theoretical house edge, not a guaranteed return in any session.
The volatility is severe. Your balance can fall through spin after spin without a return, followed by a single expanding wild that changes the result dramatically.
The review reports starting with 100,000 EUR. After 200 spins in each mode at 1 EUR per spin, the reported balances were 100,211.70 EUR in Ra mode and 100,068.60 EUR in Osiris mode.
Mobile performance
The review’s quick Chrome mobile session was described as fast, with no lag and responsive touch controls. The reels fit reasonably well in portrait view, though multiple multipliers make the text harder to read. The bright red and green palette may also feel harsh on a small display, so lowering screen brightness could help.
How Ra vs Osiris compares - other slot titles
The review compares it with two Greek-themed slots from the same developer.
| Game | Provider | Volatility | Max Win | Special Features |
|---|---|---|---|---|
| Ra vs Osiris | Pragmatic Play | High / Very high | 25,000x the bet | Mode selection, expanding wilds (up to x1000), free spins with walking wilds, gamble wheel and bonus buy. |
| Zeus vs Hades: Gods of War | Pragmatic Play | High | 15,000x the bet | Mode selection, expanding wilds (up to x100), free spins with sticky wilds and bonus buy. |
| Zeus vs Typhon | Pragmatic Play | High | 10,000x the bet | Split grid with pays both ways, random multipliers that combine, Super Free Spins with a progressive multiplier and bonus buy. |
For the largest advertised win, Ra vs Osiris leads with its high prize cap and x1000 wild multipliers. Players seeking more frequent activity may prefer Zeus vs Typhon, which has 2,048 paylines and pays both ways.
Zeus vs Hades occupies the middle ground by retaining the dual-mode structure, although its sticky free-spin wilds do not expand as dramatically.
Verdict – is Ra vs Osiris slot worth playing?
Ra vs Osiris’ strongest feature is that the base game can produce large wins without reaching the bonus. Its harshest aspect is the potential loss of an entire free-spins feature when the gamble wheel, despite its +60% chance of winning, lands on red.
This slot is aimed at experienced high-volatility players who understand the nature of the risk. Anyone who needs regular wins to remain engaged may prefer a different game.
