The moon only shines as its surface reflects light from the Sun, so it is quite understandable why the Moon Princess slot is completely eclipsed by the new Sisters of the Sun slot. The new version is very similar to the original (let's be honest) but it is far from being a copycat. The theme of Ancient Egypt is made nobly and the anime factor of the predecessor is gone.

Slot details & Wager limit

The playing field consists of 5 reels and 5 rows and has no paylines as the slot uses the Cluster Pays system. You can choose the size of the stake from the range of €0.20-€100 per spin. Centered around sister deities, it is a highly volatile game with many modifiers and other bonus features. Cascading wins generate Wild symbols and if you manage to clear the entire grid, you win 50x the stake! But keep in mind that this win cannot happen during the Sisterhood feature. The multiplier depends on the multiplier you have earned. The multiplier is increased by +1 for every win that occurs on top of the marked position and is reset between spins during the main game.

Goddess Power feature is triggered at random times during non-winning spins. Here's a quick overview of what you can get:

  • Sekhmet converts symbols
  • Hathor adds 1 or 2 Wild symbols
  • Bastet removes 2 types of symbols from the board

Sisters of the Sun RTP and Volatility

7.9 
The game is very volatile with an RTP of 96.20%. 
This slot is unlikely to suit players for whom the phrase “high volatility” sounds more like a threat than a challenge. The game is very volatile with an RTP of 96.20%. 

Sisters of the Sun Theme

8.2 
Three sister goddesses, Bastet, Hator, and Sekhmet are the main heroines of this game. They appear on the playing field as well as in the background. The background is practically absent here, only the desert landscape is visible during the next strong storm, but it looks good. To be honest, we have been tired of the Egyptian theme for a long time, but here it does not look boring because of the provider's non-standard approach.
Sisters of the Sun Theme

Sekhmet pays up to 10x, Hathor pays up to 10x, Bastet pays up to 10x and a combination of any sisters pays up to 1x. Low-paying symbols are the Snake which pays up to 3x, the Sign of Isis - pays up to 3x, the Sphinx - pays up to 2x, and the Lotus - pays up to 2x. 

Every time you hit a winning combination, all winning symbols are removed from the grid. New and/or existing symbols drop out and fill in the blanks, and this process repeats as long as you keep winning. When 3 symbols are removed, a Wild is generated in the empty space in the middle. If you manage to clear the entire grid, you win 50x your stakes. This win does not occur during the Sisterhood feature.

Bonus Rounds & Free Spins

8.6 

To activate the Bonus Round you need to jump over several hoops.

You only need 1 Scatter anywhere to get the Sisterhood feature, which gives 1 free spin with a reset win multiplier. During this feature, the 3 sister deities take turns awarding their modifier on non-winning symbols until all modifiers have been played.

Sisters of the Sun - Bonus Rounds

Did you manage to completely clear the grid during the feature? Congratulations! You activate the Bonus Round. Then you can choose between Sekhmet, Hator, or Bastet to get 4, 5, or 8 initial free spins respectively. By the way, the multiplier from the Sisterhood feature is carried over and is not reset between free spins!

You can also win extra free spins, and their number will directly depend on which Goddess you have chosen.

Sisters of the Sun Max Win

8.8 
The maximum win is 15,000x.
This is where you are properly rewarded when everything finally goes the way you want it to. The 15,000x potential is 3x that of the Moon Princess game and you can get this maximum win by activating the free spins bonus round.

Overall Rating

8.1
This slot feels like Moon Princess but from a parallel universe. They are very similar but far from the same. The anime princesses have been replaced by 3 Egyptian deities that you will have to meet to unleash the game's potential. Visually, this slot also looks more serious and its volatility is bordering on extreme. The biggest problem here is triggering the bonus round. You need to activate the Sisterhood feature in advance to at least have a chance for it.
