Sisters of the Sun by Play'n GO is a 5x5 grid slot set in Ancient Egypt, with a theme built around Ra, Sekhmet, Hathor and Bastet. The game uses a Wild symbol shown as the sun and a Scatter symbol shown as a scroll. It is a high-volatility title with an RTP range listed between 84.2% and 96.2%.
The main feature is Goddess Power, where one of the three goddesses can transform or remove symbols on the grid. This can trigger on random non-winning spins, while in Free Spins it is activated on every non-winning spin. Eye of Ra increases the win multiplier in the base game, and the effect is doubled during Free Spins.
Landing one Scatter starts Sisterhood, a round where all three goddesses use their powers in a single free round. If the grid is cleared in this feature, Free Spins are awarded. The demo version lets players play for free and practice before playing for real money while learning how the multiplier and bonus rounds work.
