Celestial Sisters Megaways: Slot Overview

Big-eyed cartoon heroines, hazy fantasy backdrops, and anime vibes—no, this isn’t yet another take on Moon Princess from Play’n GO, but Celestial Sisters Megaways from rival studio Blueprint Gaming. The two titles may look a little alike at first glance, but that’s pretty much where the overlap stops. In practice, Celestial Sisters Megaways feels far closer to Blueprint Gaming’s Bison Rising Megaways Build A Bonus. As with that release, you get the usual Megaways add-ons plus a feature buy that can reach potentially Brobdingnagian levels—something that may appeal to players who enjoy going big, very big. And yes, there are jackpots too.

Switching from bison to anime is about as sharp a turn as it gets, and Celestial Sisters Megaways is set in a bright cartoon realm of glittering oceans, cloudy skies, moons, stars, wings, and similar celestial scenery. It leans heavily into Moon Princess territory, which is probably unavoidable with this kind of theme. Beyond that, there isn’t a great deal to add about the visuals. If this style is your thing, you’ll likely be happy; if not, you can safely head elsewhere.

Hovering above the water sits the Celestial Sisters Megaways reel set. It features 6 main reels plus a 4 symbol tracker reel across the top that spins horizontally. The main reels land varying symbol counts, creating a win-ways range from 324 up to 117,649—and when purchasing the bonus, it’s possible to lock in a minimum Megaways level. Stakes run from 10 p/c to $/€10, and the jackpot system can be played at any bet size. Rated medium-high volatile, Celestial Sisters Megaways has an RTP of 93.99%, while the bonus buy RTP is 94%.

Celestial Sisters Megaways includes 10 paying symbols split into three tiers. The heart, moon, and star are the low symbols, paying 1x the bet for six. Next are the winged star, bell, and golden moon-like symbol, which return 1.5x the bet for six. At the top are 4 character premiums, paying 2 to 50 times the stake for a 6 OAK hit. With the cascading mechanic, winning symbols are removed and replaced by new ones dropping in from above on the main reels or sliding in from the side on the top tracker reel. Cascades continue until no further wins appear. Assisting with combinations is the wild, which appears only on the tracker reel and substitutes for any standard paying symbol.

Celestial Sisters Megaways: Slot Features

Celestial Sisters Megaways combines familiar mechanics such as mystery symbols and free spins with an increasing multiplier, alongside operator-linked jackpots and a Build a Bonus add-on.

Mystery Symbols

Whenever mystery symbols appear, every one shown reveals the same random symbol. Any symbol can be chosen except the scatter symbol or the wild.

Free Spins

The free spins feature triggers when at least 4 scatter symbols land. If more than 4 scatters activate the bonus, extra free spins are added based on the chosen free spins option. Before the round starts, players can select the volatility level from the following choices:

• 15 free spins with a starting win multiplier of x1. Each extra triggering scatter awards +4 free spins.
• 10 free spins with a starting win multiplier of x5. Each extra triggering scatter awards +2 free spins.
• 5 free spins with a starting win multiplier of x10. Each extra triggering scatter awards +1 free spin.
• A random number of free spins with a random starting win multiplier from the available free spins and multipliers.

During free spins, the win multiplier is increased by +1 after every reaction, and hitting 3 or 4 scatter symbols grants +5 or +10 more free spins, respectively.

Pot System

This bonus begins when 6 overlay symbols land. Progress is made by climbing a win ladder, and reaching the Super feature area is where jackpots can be won.

Build A Bonus

Build A Bonus functions like a high-powered feature buy menu. Using Build A Bonus, players can select 10 to 20 free spins, a starting win multiplier of x1 to x10, and a minimum number of Megaways from 324 to 117,649. Pricing ranges from 52 to 7,378 times the bet.

Celestial Sisters Megaways: Slot Verdict

After spending time with Celestial Sisters Megaways, it’s not entirely straightforward to pin down. On the one hand, it delivers a very typical Megaways toolkit—mystery symbols, reactions, and a four-way free spins pick with a climbing win multiplier. It’s all fairly standard stuff you’ll see across plenty of other titles. The free spins selection is a bit less common, but the rest is as familiar as it gets. On the other hand, Celestial Sisters Megaways throws in a few surprises, with the standout being the Build a Bonus option, which becomes genuinely intimidating when pushed to the top end and probably isn’t something to treat casually.

That leads into another point: Celestial Sisters Megaways brought back the question of whether bonus buy results should be viewed as multipliers of the base stake or multipliers of the purchase price. The reason is that while the base game tops out at 10,000x, Build Your Bonus can reach up to 250,000x the base bet. That’s huge, but it equates to roughly 33.88x the cost of the priciest buy. Granted, paying 7,378x does load the feature with plenty—maximum Megaways for the entire session plus 20 free spins starting at x10. Still, that’s a serious outlay. To be fair, there are also far more affordable configurations.

Alongside Build a Bonus, two more draws are the jackpots and the Moon Princess anime/manga styling. Even so, Celestial Sisters Megaways remains a bit of a head-scratcher. If you’re looking to go big—really big—it offers a huge chance to do exactly that, much like Bison Rising Megaways Build A Bonus, which Celestial Sisters Megaways essentially mirrors, only with jackpots added. Yet by wrapping the whole package in an anime coating, Celestial Sisters Megaways ends up feeling fairly distinctive. Whether that’s a good kind of unique is debatable, but it’s easy to see how some players could be tempted by the high-stakes buy potential and/or the jackpots.
