How to play Sisters of the Sun mobile slot

The Sisters of the Sun slot is played on a 5×5 grid where 3 goddesses fight to give you huge riches and a top win of 15,000x your bet.

This is not a cluster pays slot in the traditional way, but it has got the same kind of elements. For one, wins are achieved by getting 3 or more symbols in a row horizontally or vertically, anywhere on the reel.

For two, every win explodes, and more tumble down from above, giving you another chance at a win. It’s this energy that livens every spin of this Sisters of the Sun mobile slot, especially with that gorgeous Ancient Egyptian slot theme.

If you’ve ever played on the Rise of Olympus online slot, you’ll recognise many of the mechanics here. If you haven’t now you know that if you like one, you’ll definitely like the other.

Sisters of the Sun slot has three main features

And three main goddesses. See the connection? They sit by the side of the reels, and on a non-winning spin they might pop in and randomly trigger any of the following:

  • Sekhmet: Upgrades one symbol into another
  • Hathor: adds 1 or 2 Wild symbols to the reels
  • Bastet: removes two sets of symbols to give you another win

And that’s not the only time you’ll get this feature. In fact, if you get just one scatter you’ll trigger The Sisterhood Feature, where each of the goddesses take turns triggering each of the features. And if you clear the grid you’ll trigger the free spins bonus round.

How the Free Spins and Multipliers Work Together

On every spin, the Eye of Horus covers 5 squares of the grid. Get a win on the cases and the multiplier increases by 1 on each cascade, and then reset on the next spin. That’s the base game.

But if you trigger the Sisters of the Sun free spins, you’ll get 10 cases instead of 5, which is where the multipliers really go into overdrive as they don’t reset between spins and you have a higher chance of getting more wins over the cases.

You might have to take a bigger gamble than you think, as you’ll have to pick from one of the goddesses who, on a losing spin, will always trigger. However, 4 free spins are not always enough, and this Sisters of the Sun slot game is more volatile than most.

A great addition to the Play’n GO slots collection, sitting next to the strangely brilliant Gold Volcano slot or the Twisted Sister game.

Bonus Features

Eye of Ra Multiplier: Before you spin, 5 random grid locations are marked with the Eye of Ra. When you get a win on an Eye of Ra, the multiplier increases by 1x. This can continue growing with each avalanching win on an Eye of Ra.

Tumbling Reels: On every win, the symbols explode, and more tumble down from above to potentially create new wins.

Wild Creation: The wild symbols substitute for all symbols except Scatter. However, you can only create a wild symbol in the middle of a winning combination.

The Goddess Power Feature: Triggered at random on a non-winning spin, depending on the goddess on-screen, you'll trigger one of the following reels:

  • Sekhmet: coverts one set of symbols into another symbol.
  • Hathor: adds 1 or 2 Wild symbols to the grid.
  • Bastet: removes two sets of symbols from the grid.

The game opens with a random goddess, and changes in the following order: Sekhmet – Hathor – Bastet.

The Sisterhood feature: triggered with 1 Scatter symbol, you'll get one free re-spin with the win multiplier reset.

In this feature, each one of the three goddesses will perform their respective abilities on each symbol drop that does not provide a winning combo. If you clear the grid during this bonus round it will trigger the Free Spins only; no instant prizes.

Free Spins: If you clear the grid on this sisterhood feature, you'll trigger the free spins. You'll then be able to choose between the following features:

  • Sekmet 4 free spins
  • Hathor 5 free spins
  • Bastet 8 free spins

Every single scatter provides extra free spins up to a maximum of 150 spins. The multiplier from the Eye of Ra feature is carried over from the base game and you get 10 spaces instead of 5. During the free spins, the multiplier doesn't reset per spins, but keeps on climbing.

If you do get a losing spin, the feature of the goddess you've chosen will trigger.

Clear the Grid: Completely clear the grid of symbols (except during the Sisterhood feature) and you'll get an instant prize of 50x your total bet multiplied by the Eye of Ra Multiplier.


  • High 15,000x bet max win
  • High 96.2% RTP
  • Free spins with multipliers
  • Tumbling reels for more action


  • Too high variance for some

Sisters of the Sun Review Conclusion

The Sisters of the Sun slot is a brilliant grid game that follows along with the pattern of so many great Play'n GO slot machines.

From the avalanching reels that give you bigger multipliers on wins to three goddesses who give you features often.

The RTP of 96.20% is healthy and the low minimum bet of 0.20 a spin makes it very playable. Especially as with a mid to high variance machine, the top win of 15,000x your bet feels closer than in most other grid slots.

If you love the Moon Princess slot, you'll enjoy this Sisters of the Sun game.
