This is a slot created by Play’n Go, and it is has a grid construction of 5×5. It has a cascade system in place, meaning that symbols will fall down the grid to create winning combinations. The winning combinations in Sisters of the Sun are created when three or more symbols are in a row. The winning symbols are then removed, and new ones take their place.
There is a Wild symbol as well that replaces all other symbols, except the Scatters. The Wild can be created, and it appears in the middle of the grid when a winning combination is removed. The Wild is also removed when there are no symbols remained. There are two occasions in which the Wild appears: during the first spin, or during the Gift of Ra Mechanic, which will also see the Scatter added anywhere once the spin comes to an end.
During every spin, the Eye of Ra will fill out five random grid locations, and the multiplier will increase by one when there is a win over a location that has an eye, and it will reset before the new spins. This is not valid when the player has triggered free spins.
There is also a Goddess Power feature that will be activated at random times on non-winning spins. The goddess will help players to create a win, thanks to her unique ability. The order of the goddesses is fixed, and the active goddess will change each time the feature is activated. The order of the goddesses is the following:
- Sekhmet – it will change one set of symbols to other ones;
- Hathor – will add one or two additional Wild symbols;
- Bastet – will remove a couple of sets of symbols.
The next feature is the Sisterhood, which is activated with one Scatter symbol, and one free round will be handed to the player, with the multiplier resetting. Each symbol that does not provide a winning combination will be subject to a Goddess Power, and it will occur until the three goddesses have finished with their abilities. If the player clears the grid during this free round, they will activate the free spins.
Before the free spins begin, the player will need to choose one of the goddesses:
- Sekhmet – will award four spins;
- Hathor – will award five spins;
- Bastet – will award eight spins
During the free spins round, the location in which the Eye of Ra will be present will increase to ten, and the chosen goddess will be active on every non-winning spin. Here, the Sisterhood feature cannot be triggered. The Scatter will get players additional spins, and the maximum players can get is 150. Sekhmet will award four additional spins, Hathor will get players three, and Bastet will award two additional spins.
If the player clears the grid of all symbols, they will get an instant prize. This does not occur when the Sisterhood feature is active. The prize that they can get is 50x the bet multiplied by the win multiplier when the grid was cleared. Can be played here
