Moon Sisters (3 Oaks Gaming (Booongo)) – Review & Demo Play

Moon Sisters Symbols and Paytable

I see 8 pay symbols in Moon Sisters, split evenly into low and high pays. Low pays are the card ranks from J to A, all sharing equal values that peak at 2x your bet for a five-of-a-kind. High pays are a flower, a butterfly, and the two titular sisters. Payouts scale in a neat ladder: the second sister pays up to 8x, then 6x and 4x follow, while the more valuable sister can deliver up to 10x for five.

Specials include Fish Wilds and Moon Bonus symbols. I use Wilds to substitute and complete wins, while Moon Bonus symbols are tied to the Hold and Win core. Regular Moons carry cash values that can reach up to 25x your bet, and they are the pieces you want stacked when the feature lands. Jackpot Moon Bonus symbols also appear and can award fixed prizes: Mini worth 30x and Major worth 150x your bet, with all visible bonus values paid at the end.

Moon Sisters Slot Features

When 6 or more Moon Bonus symbols hit in a single spin, the Hold and Win feature triggers. All triggering Moons turn Sticky and 3 respins roll. Any new Moon symbol resets the counter back to 3, and the bonus keeps going until you run out of respins or fill the entire board. At the close, every Moon value in view is collected. I aim for the full screen, as that drops the Grand jackpot of 1,000x your bet on top.

Review Summary – Moon Sisters

Moon Sisters is a fairly adequate Hold and Win slot with an Asian theme centred on the two sisters. The production values are pretty average, though the package is serviceable. I like the focused experience: it really only has its Hold and Win feature to capture your interest. That means no free spins or extra frills, which some will miss. For me, it suits a quick session when I want straightforward respin action without juggling several mechanics at once.

The model sits at medium volatility with a theoretical RTP of 95%, which is a notch below the industry average. The grid is the familiar 5 reels, 3 rows and 25 betways, and the Grand jackpot clocks in at 1,000x your bet. Stakes run from £0.25 up to £60 per spin, so casual play and testing higher steps are both on the table. I found the maths steady enough, but the lower RTP does shave a bit off the long game.

As for highlights, the Hold and Win loop is tidy and can bring decent boards when Moons keep landing. Regular symbols can reach 25x and the Jackpot Moons add Mini at 30x and Major at 150x, with the full grid paying the Grand. Still, with no gameplay features aside from Hold and Win, it can feel a hard sell next to richer builds. I keep it for moments when I want that single-mode grind and a shot at the 1,000x.
