Sisters of the Sun Slot Review

The sun god Ra has bestowed magical powers to the goddesses Sekhmet, Hathor and Bastet in the Sisters of the Sun slot, an unusual ancient Egyptian-themed game from Play ‘n GO. Played on a 5x5 grid, wins are formed by landing 3 or more matching symbols vertically or horizontally. Symbol drop wins create wilds which can boost your winning chances. Land a win that includes 1 of 5 randomly chosen symbol positions and it brings an increasing multiplier into the mix. The 3 Goddesses can each deliver a special wild or symbol swap modifier. These can combine during the Sisterhood feature. There’s also a Free Spins feature where the modifiers can really work some magic. Find out more in our complete Sisters of the Sun review.

Sisters of the Sun Slot RTP, Details & Wager Limits

The Sisters of the Sun slot is played on a 5×5 symbol drop grid. Create winning combination by landing 3 or more matching symbols vertically or horizontally.

Stakes in this game range from between 20p and £100 per spin. With 5 bet levels appearing below the reels, click on the plus and minus buttons to adjust accordingly. In some countries, there are AutoPlay and Turbo Mode functions.

The Sisters in the Sun RTP is 96.2% which is Play ‘n GO’s default return to player rate and above the 96% average. Many slots from this provider are extremely volatile. This Egyptian adventure isn’t as stratospheric as some but it’s fiery enough.

On a scale of 1 to 10, I’d put the Sisters of the Sun volatility at 8. The maximum win here is 15,000 x your total stake from a single spin. The chances of winning this is 1 in 1 billion spins.

Theme – Audio & Design Features – join ancient Egyptian Sun goddesses  


With an ancient Egyptian theme, the Sisters of the Sun is based on sun goddesses Sekhmet, Hathor and Bastet who Sun God Ra has bestowed powerful gifts upon. With plenty of visual flair, there’s an obvious Egyptian flavour to the design but it’s a bit different from the usual collection of symbols and objects found in slots with this theme.

You’ll see an animated goddess floating alongside the game grid. This indicate which goddess is active which can impact on the modifiers. The modern design here is stylishly done.

Set against a desert backdrop with pyramids in the distance, the reels are made up of stylized versions of standard Egyptian hieroglyph symbols. The most rewarding symbols are the 3 Goddesses who each pay 0.3, 1.2 or 10 x your total stake if you land 3, 4 or 5 on a payline.

Any combination of 3 or more goddesses also delivers a payday of 0.2, 0.8 or 5 x stake. The wild can only appear following a symbol drop. This replaces all the standard symbols and offers payouts of 1, 4 or 30 x your total stake. There’s also a scatter.

Sisters of the Sun has been fully optimised for play on all devices including mobiles and tablets as well as desktop computers. The stylish visuals mean you won’t lost anything by playing Sisters of the Sun on a handheld device.

Sisters of the Sun Bonus Features

If you like slots that deliver varied gameplay, you’ve come to the right place in Sisters of the Sun. As well as symbol drop wins, you’ll find a host of special modifiers, multipliers, free spins and other goodies in this Egyptian extravaganza. In total, there are 5 bonus features.

Cascading Wins feature

When a winner is formed, those symbols are removed from the grid. Called the Cascading Wins feature, a wild appears in the middle position when a 3-symbol winner is removed.

If you manage to clear the whole of the reels of symbols, you’ll receive a bonus prize equal to 50 x your total stake. The only exception being if you clear the grid during the Sisterhood feature. I’ll look at this in detail below.

Eye of Ra feature

On each spin, 5 randomly chosen positions on the game grid will appear the Eye of Ra feature. If you land a winning combination on an Eye of Ra, it increases the win multiplier by 1x. These can increase during a set of symbol drop wins. The multipliers resets with each new spin.

Goddess Power feature


The Goddess Power feature can trigger at random on any winless spin. You’ll then benefit from 1 of 3 modifiers. Which one you get depends on which goddess is currently active on the screen:

  • Sekhmet: transforms 1 set of symbols into another symbol
  • Hathor: adds 1 or 2 Wild symbols to the reels
  • Bastet: removes 2 sets of symbols from the reels

A new payout consideration follows after the modifier has been activated.

Sisterhood feature

Trigger the Sisterhood feature by landing just a single scatter symbol. You’ll then receive 1 free spin with the multiplier reset to 1x. A series of symbol drops then follow with the Sekhmet, Hathor and Bastet modifiers playing out in turn, complete with potential Eye of Ra multipliers.

Free Spins feature


Trigger the Free Spins feature by clearing the whole of the game grid of symbols. Any multipliers active from the Sisterhood Feature carry over into the free spins.  Then choose 1 of the 3 Goddesses:

  • Sekhmet = 4 free spins
  • Hathor = 5 free spins
  • Bastet = 8 free spins

During the free spins, the number of Eye of Ra symbol positions doubles from 5 to 10 which boosts your chances of bringing multipliers into play. On every winless free spin, your chosen Goddess’s modifier triggers.

Land scatters to add extra free spins to your total too. Sekhmet, Hathor and Bastet receive 4, 3 or 2 extra spins for each scatter that lands. It’s possible to land up to 150 free spins during this round.

Sisters of the Sun Review Summary – action-packed trip to ancient Egypt

The theme in the Sisters of the Sun slot might by very familiar but the design and gameplay are a little different from your common or garden trip to ancient Egypt. In fact, when it comes to gameplay, it’s a sequel to Moon Princess which has a Japanese Manga theme.

However, Play ‘n GO has ramped things up by offering bigger max wins compared to Moon Princess (15,000 x stake vs 5,000 x stake). The RTP is lower (96.2% vs 96.5%) but there potential makes up for this.

Sisters of the Sun is stylishly put together with the features offering plenty of variety. If you enjoy a classical age adventure but fancy trying something a bit unusual, this game ticks just those boxes. In summary, we had joy, we had fun, we had Sisters of the Sun (sorry, couldn’t help myself).

If you want more trips to ancient Egypt, Play ‘n GO’s very own Book of Dead has become the go-to slot. I would personally opt for Cleopatra 2, by IGT, which comes with multipliers up to 50x in the free spins as well as 50,000 x stake max wins.
