Sisters of the Sun Slot Overview
Sisters of the Sun is a 5x5 video slot from Play'n GO, released on 2021-09-02. It uses a grid layout rather than fixed paylines, with wins formed by 3 or more matching symbols in horizontal or vertical connections. From a math perspective, the key hook is the carried multiplier from Eye of Ra, which can scale the 50x full-clear award inside Free Spins.
I see a high-volatility profile here, rated 8/10 in one source, with default RTP at 96.20% and max exposure at 15,000x. The numbers tell you the game is built around bonus conversion rather than steady base-game return. The base game can drag a bit, but the one-scatter trigger for Sisterhood keeps the feature entry logic unusually accessible.
Sisters of the Sun Symbols: Paytable & Payouts
5 reels and 5 rows are filled with low pays such as green plant, cat, white pearl and cobra, while Bastet, Sekhmet and Hathor are the premium symbols. Looking at the paytable structure, 5 low symbols pay 2x to 3x, while 5 of any single goddess pay 10x. A mixed 5-symbol combination of the three goddesses pays 5x.
Wilds substitute for standard symbols but not for the scatter. One source adds a mechanical detail that matters, a wild is created on the middle reel after removing a winning 3-symbol combination. Scatter is the entry symbol for Sisterhood. Eye of Ra is not a pay symbol in the normal sense, it is the multiplier engine.

Sisters of the Sun Slot Features
Cascade removal is the base engine. After each win, matched symbols disappear and the remaining symbols fall. On non-winning spins, Goddess Power can trigger randomly. Sekhmet converts one set of symbols into another, Hathor adds 1 or 2 wilds, and Bastet removes 2 sets of symbols. That means dead spins are not always dead, which changes the usual high-volatility rhythm.
One scatter starts Sisterhood. During this feature, every no-win result activates all three goddess powers in sequence, Sekhmet first, then Hathor, then Bastet. If that sequence clears the whole grid, Free Spins begin. I like the conversion logic here because the trigger path is staged, scatter first, full clear second, so bonus access is easier than bonus completion.
The free spins choice changes both spin count and re-trigger value. Sekhmet gives 4 spins and each scatter adds 4 more, Hathor gives 5 spins and each scatter adds 3, Bastet gives 8 spins and each scatter adds 2. The maximum is 150 spins. From a math perspective, Sekhmet is the highest-risk option, Bastet is the longest-session option, and the carried multiplier is the main EV driver in all three.

Sisters of the Sun Volatility: Win Potential & RTP
96.20% RTP, high volatility and a 15,000x maximum win define the model. No source provides hit frequency, so I would not force a number. What I can say is that the return concentration is clearly top-heavy. The 50x full-clear payout only applies in free spins and is multiplied by your current multiplier, which is where the largest outcomes sit.
Five Eye of Ra symbols are present on base-game spins, and each one included in a win adds 1 to the multiplier. The multiplier resets to 1x after a non-winning cascade chain in the base game, but in free spins it carries between spins and the number of Eye of Ra symbols rises to 10 per spin. The numbers tell you the bonus has a much stronger snowball effect than the base game.
