Sisters of the Sun: Slot Overview
According to the Law of Polarity, everything in the universe has an opposite - commonly known as yin and yang. An old text called the Kybalion builds on this by saying, 'opposites are identical in nature, but different in degree, extremes meet, all truths are but half-truths; all paradoxes may be reconciled.' That brings us to Sisters of the Sun by Play'n GO which is the yin to Moon Princess' yang. The two games have more similarities than opposites, though. What's different is the theme and a couple of feature tweaks which have tripled the older game's winning potential.
You could say the opposite of the moon is the sun, and Sisters of the Sun takes place in one of the sunniest spots on earth. We are talking about the hot sands of Ancient Egypt, where the sisters of the tale are three daughters of the Sun God Ra – Sekhmet, Hathor, and Bastet. The gaming occurs on a 5x5 sized grid where winning combinations are formed when three or more matching symbols land adjacently, horizontally or vertically. Egypt is a common theme, as you are no doubt aware, though Sisters of the Sun's representation of it isn't quite so typical. The Pyramids are there, yet the view alternates between a fiery canyon on Mars-like scene to a cloud-filled sky. It doesn't have the fun cheesy anime feel Moon Princess had, but it is an exotic entry into the grid slot genre.
Play'n GO has tinkered with the math model while changing the looks, where potential has received the biggest change. Default RTP is slightly lower than Moon Princess at 96.2%, while volatility remains high at 8 out of 10. Be aware as RTP varies depending on the market, so it can be set to lower levels than the default value. Playable on most devices, stakes range from 20 p/c to $/€100 per spin.
Checking up on the paytable reveals seven paying symbols, a wild and a scatter. Starting with the lower value pay symbols, you'll come across leaves, cats, jewellery, and snakes at the bottom end. Bastet, Hathor, and Sekhmet are the three premium symbols; these are all worth 10 times the stake for a line of five. You can mix the premiums as well to trigger a reward of up to 5 times the stake of five if any of the characters line up.
Worth even more, at 30x the bet for five of a kind is the dual snaked wilds symbol. As well as being the most valuable tile, it substitutes for all symbols except the scatter. Wilds only appear from the cascading feature covered below.
Sisters of the Sun: Slot Features
Overall, the features in Sisters of the Sun are similar to those available in Moon Princess. However, there aren't exact copies, and the changes can now lead to much more lucrative results. When players land a winning line, the respective symbols are removed from the grid, and the remaining symbols drop down to potentially create new hits. The cascading mechanism continues as long as new wins continue to land.
When a combination of 3 symbols is removed, a wild symbol is placed in the empty middle position. If the grid is cleared of symbols, then 50x the bet is awarded (except in the Sisterhood feature, explained below) and is multiplied by the active win multiplier.
On each spin, 5 random positions on the grid are marked with the Eye of Ra. If a win occurs over an eye position, the win multiplier increases by one. In the base game, the win multiplier resets between each paid spin.
Next is the Goddess Power feature, triggered randomly on non-winning spins. Whichever sister is displayed on screen unleashes her modifying abilities:
- Sekhmet – converts a set of one symbol type into another symbol type.
- Hathor – adds 1 or 2 wilds to the grid.
- Bastet – removes two symbol types from the grid.
Keep an eye out for the glowing scroll symbol. This is the scatter and landing just one triggers the Sisterhood feature. One free round is awarded, and the win multiplier is reset. During the Sisterhood feature, a Goddess Power is awarded on each non-winning symbol drop until all three goddesses have performed their modifier. Moreover, clearing the grid during this feature triggers free spins.
Before the bonus begins, players choose Sekhmet, Hathor, or Bastet to collect 4, 5, or 8 initial free spins, respectively. As is the case with Moon Princess, the option with fewer spins means higher risk/rewards, and vice versa. The win multiplier carries over from the Sisterhood feature and does not reset until the feature is over. In addition, extra Eyes of Ra appear on the grid, now 10 are used. Whichever goddess is chosen, her power is triggered on every non-winning spin. The scatter symbol still appears too, so landing one in the Sekhmet, Hathor, or Bastet round awards +4, +3, or +2 free spins, up to a maximum of 150.
Sisters of the Sun: Slot Verdict
Like its predecessor, there is a lot going on in Sisters of the Sun, and it gets outrageously manic at times – increasingly so due to the updates. Sisters of the Sun is a tougher, more volatile game because of the changes, and some players will relish the challenge, while others might prefer the technically 'softer' option of Moon Princess since both offer a similar style of gameplay.
One of the big challenges is triggering free spins. Now it can only be done by clearing the grid during the Sisterhood feature, compared to at any time in Moon Princess. There is a consolation prize of clearing the grid outside the Sisterhood. Yet even that has been reduced to 50x the bet from the 200x you can collect for doing so during Moon Princess' free spins.
Rule changes like this, as well as needing Eyes of Ra to increase the multiplier, make Sisters of the Sun harder to get up to speed, but once it gets going, it'll power past Moon Princess and leave it in the dust. For one, you can win a lot more free spins this time – 150 compared to 20, plus there is no mention of the win multiplier being capped at x20 like it was before. Add these changes together, and players can now win up to 15,000 times their stake, triple the princesses.
Play'n GO has increased the risk/reward quotient for Sisters of the Sun, but it doesn't automatically eclipse Moon Princess, though. The original blended chaotic action with an equally off the wall theme, all Bandai, Moon Sailor rolled into a shojo manga bonanza. Sisters of the Sun is arguably better suited to a different type of gambler, one keen to take on a more challenging game to potentially reap greater rewards - should it shift out of second gear.
Don't Miss
Play'n GO has also created a Christmas version of this game titled Moon Princess Christmas Kingdom. Based on the original Moon Princess slot released back in 2017, it offers wins of up to 15,000 times your stake.
