Pragmatic Play just dropped Ra vs Osiris (September 2026), and if you played Zeus vs Hades - Gods of War, you're going to feel right at home here. It shares that game's 5x5 board and 15 lines. They've kept the cool "choose your volatility" mechanic but swapped the Greek gods for an Egyptian theme. The biggest change, though? They've ditched the sticky wilds for a walking multiplier mechanic, and it completely changes the vibe of the game.

Ra vs Osiris base game on the Ra side with two expanded wilds, 2x on reel 1 and 3x on reel 3, paying 194x the bet
Two wilds expanded at once, 2x and 3x, and because their multipliers add, every line through both of them paid five times over.

How the Bonus Actually Plays

The bonus round is where the magic (and the stress) happens. Landing 3 to 5 scatters gets you 6 free spins with a guaranteed minimum multiplier of 2x, 4x, or 8x.

This is what a walking wild buys you: the 5x has stepped all the way to reel 1, so every one of the 15 lines now starts on a multiplier, and the free spin counter hasn't moved.

Before the spins start, the game gives you a gamble wheel where you can try to push that minimum multiplier all the way up to 100x. But fair warning: if you lose the gamble, your bonus is gone. It's a sweaty feature, and I usually skip it unless I'm feeling incredibly lucky.

The gamble in plain numbers: roughly a five-in-eight shot at doubling the floor from 2x to 4x, and a loss means no free spins at all. I took the 2x.

Once you're in the bonus, it's all about the walking wilds. If a wild lands and completes a win, it expands, grabs a random multiplier, and triggers free respins. With every respin, the wild takes one step to the left until it falls off the board. The best part is that these respins don't eat into your 6 free spins. If you manage to get a couple of wilds walking at the same time, their multipliers add together, and the round can go on for ages.

The Highs and Lows of Buying the Bonus

You have to choose between playing as Ra or Osiris, and Osiris is the "extreme" mode. Because of this, everything on the Osiris side costs exactly double. A standard bonus buy is 100x your bet on Ra, but 200x on Osiris.

On the Osiris side the buys cost double what Ra charges, 200x for the regular round and 500x for the one that locks the floor at 8x.

In my session, I saw both sides of this brutal volatility.

  • The Good: I bought a 200x Osiris bonus and started with the basic 2x floor. I landed one wild that walked for a couple dozen respins and paid 187x. On the very next free spin, another wild dropped and walked for a dozen more, paying 239x. I more than doubled my money, and it was entirely because the free respins kept the board alive.
  • The Bad: Later, I splurged on the 500x Osiris "super buy" (which guarantees an 8x multiplier floor). I even landed a 20x wild during the respins, but the round still came up well short. I ended up getting back only about a third of what I paid. Ouch.

The 500x round at its best moment, a 15x and a 10x on the board together. The 8x floor lifts every wild that lands, and here two of them are working the same lines at once.

The game also lets you buy special base-game spins that guarantee a wild, costing anywhere from 20x up to a massive 1000x on Ra (and double on Osiris!). But the wild only expands if it completes a win. Paying that much money just to watch a wild sit there as a dead tile is a terrible feeling, so tread carefully with those.

How it Compares

Ra vs Osiris feels like a clear step up from Zeus vs Hades. They dropped the free spin count from 10 to 6, but they made up for it by raising the wild multiplier limit to 1000x, bumping the max win to 25,000x, and slightly increasing the RTP to 96.53%.

It reminds me a bit of NetEnt's Jack and the Beanstalk 2 because of the walking respins on a 5x5 grid, but the massive random multipliers here make it way more explosive. Pragmatic also has Thunder vs Underworld 250 if you want this same grid with locking wilds and a friendlier, medium-volatility math model.

If you like high-risk, high-reward slots, this is a great release. The walking wilds make the leftmost reels incredibly valuable and the bonuses feel much more dynamic than the old locking wilds. Just respect the volatility, especially on the Osiris side, because this game can drain your balance just as fast as it can multiply it.
