Sisters of the Sun is a 5x5 grid slot game. Symbols cascade down the grid with the aim to create winning clusters which are achieved by getting three or more symbols in a row. Winning symbols are then removed for new symbols to take their place.
The Wild symbol substitutes for all symbols except Scatter. Wild symbols can only be created; appearing in the middle when a winning combination of three symbols is removed. Wild symbols are removed when no other symbols are remaining to completely clear the grid of symbols. The Scatter symbol can appear during the initial spin, or via the Gift of Ra mechanic where the Scatter is added randomly anywhere once the spin ends.
On each spin, five random grid locations are marked with the Eye of Ra. The win multiplier increases by one when winning over an eye location; resetting before each new spin (except when Free Spins are triggered). Winning combinations multiplied by the currently displayed value. The win multiplier only increases once per eye location won on.
The Goddess Power feature is triggered at random on non-winning spins. Depending on the active goddess shown on-screen, a unique ability is performed to help create a win. The game opens with a random goddess, with the order of goddesses fixed to Sekhmet – Hathor – Bastet. The active goddess changes after each Goddess Power activation
