Sisters of the Sun Review

If you’ve ever played Moon Princess, then you’ll instantly know what Sisters of the Sun is all about. Despite the radically different Ancient Egyptian theme on display, complete with a sand-swept desert in the background, the slot’s cascade mechanics and 5×5 game grid will feel pretty familiar. The team at Play’n GO have done a great job at retaining all the popular features of its predecessor whilst tweaking the stats to give this game a bigger max potential of 15,000x your bet. However, the change to the way free spins are triggered could be a sticking point for some. So, will Sisters of the Sun shine on brightly or get lost in a heavy sandstorm? Read our complete review now to find out!

Sisters of the Sun Bonus Features

Sister of the Sun follows in the footsteps of Moon Princess when it comes to the raft of bonus slot features on offer. Cascade mechanics are employed here, and lines of 3 or more symbols disappear from the grid, leaving a wild behind. 5 wilds in a winning line gets a 30x your stake reward, whilst clearing the grid entirely rewards 50x your bet. Wins occurring on a highlighted Eye of Ra space will increase the progressive multiplier, and this does not reset in the free spins bonus feature. Any of the 3 randomly triggered Goddess Power modifiers will bring extra benefits, plus all 3 will activate in sequence if the Sisterhood feature is triggered. Clearing the grid during that feature is your ticket to the lucrative free spins round and a shot at the slot’s 15,000x your bet max potential.

Cascade Mechanics

When a connected line of 3 or more matching symbols forms on the grid, they will evaporate, allowing the symbols above to cascade down and fill in the gaps. Any further wins will trigger yet more cascades and potential wins from a single paid spin. A 50x your bet prize is awarded for entirely clearing the grid of symbols before being multiplied by the current win multiplier amount. This won’t apply during the Sisterhood feature.


Look out! There are two snakes on the grid, but they are friendly, acting as the wild symbol and substituting for all paying symbols they award 30x your stake if 5 appear in a winning line. Each time a combination of 3 symbols disappears from the grid, it leaves a wild behind in the central spot.


A glowing scroll symbol appears as the scatter in Sisters of the Sun, and you’ll only need to land 1 to trigger the Sisterhood bonus feature.

Eye of Ra

5 random spaces will be highlighted with the Eye of Ra symbol before each spin. The win multiplier will increase by +1 when a winning combination forms over a highlighted position and resets before each new paid spin in the base game.

Goddess Power Feature

The Goddess Power feature can be triggered randomly on a non-winning spin, activating one of the following modifiers: Sekhmet – changes one symbol type into another. Hathor – places 1 or 2 wilds randomly onto the grid. Bastet – makes 2 symbol types vanish from the grid.

Sisterhood Feature

Landing a single scroll scatter will reset the win multiplier and award you with 1 free round of the Sisterhood feature. You’ll be awarded with a new Goddess Power feature on each non-winning symbol drop, cycling through all 3 of the Sister’s modifiers. If you manage to clear the grid here, the free spins round will automatically trigger.

Free Spins

Once the free spins round triggers, you get to choose a goddess, with Sekhmet, Hathor, and Bastet granting you 4, 5, and 8 free spins, respectively. Your selected goddess will also apply her modifier to the grid on each non-winning spin. For each scatter symbol appearing, you’ll claim an additional 4, 3, or 2 free spins for going with Sekhmet, Hathor, or Bastet, respectively. The good news is, the win multiplier doesn’t reset until the feature is finished, and any total gained in the Sisterhood feature will be carried over. You’ll also have 10 Eye of Ra symbols appearing on the grid with each spin.

Sisters of the Sun Jackpot

Praying to the Egyptian Goddesses for a jackpot won’t make one appear, but with a max potential of 15,000x your bet to chase, it’s not such an issue.

RTP and Volatility

You’ll encounter high volatility and a 96.20% RTP setting in Sisters of the Sun. Just be sure to check before you play, as some casinos may be offering some lower RTP ranges.
