We observed that this slot skillfully employs cluster pays for combinations to deliver thrilling gameplay. While we noticed some similarities with Hacksaw Gaming’s previous titles, Sun Princess stood out due to its unique 7x7 grid and innovative spreading mechanics.

Everything About the Graphics and Sound of the Sun Princess Slot

We observed ethereal settings which resemble Hacksaw Gaming's other princess slots are known for but with a brighter gold hue overall. The base game takes place in front of a short stairway leading into a palace with tall arches all draped with leaves and bushes. To the right of the grid, we find the princess in a white and gold dress fit for a Greek goddess.
The score of the game provides a subtle and appropriate assortment of wind and string instruments in a repetitive loop which we found enchanting.

How to Play the Sun Princess Slot
Sun Princess features a 7x7 grid with winning combinations forming when at least 5 matching pay symbols connect in a cluster. The Chain Reaction feature is linked to the slot’s spreading mechanic, which adds a unique twist on the base game and bonus game. Don’t worry, we'll explain it below.
Betting ranges from 0.10 to 100 per spin. Clusters comprising 5 symbols pay 0.1x to 1x the bet, while a full grid of 49 matching symbols can be worth up to 10,000x your bet. Wild symbols help by substituting for all paying symbols. Manually the game can feel a bit slow, especially if you don’t activate any Bonus Buys. But you can use the auto-spin feature to keep making plays on your behalf.
Give the Sun Princess Demo Version a try
Given the game’s unique spreading mechanics and layered bonus features, which differ from most cluster pay games, we really believe players should give it a test run with the free Demo Version to understand the slot. It allows you to explore how Sun Ray Frames interact with Wilds and Multipliers, and we found it super helpful for understanding when to engage Bonus Buys.
Bonus Features in the Sun Princess Slot
We found that Sun Princess’s unique features and mechanics truly add depth and excitement. Here's what stood out:
Sun Ray Frames & Chain Reaction
Sun Ray Frames that land on symbols or wilds at the start of a spin activate after wins are evaluated. When triggered, they spread in straight lines, transforming all symbols in their path into the same as the original. These rays can spread vertically, horizontally, or in all four directions to the edges of the grid to provide additional wins. But it doesn’t stop there! If a Sun Ray hits a wild, it adds a 2x multiplier, which increases by 2x each subsequent time it is struck.
Multiple multipliers in the same win are then compounded before being applied. We also observed that only one Sun Ray Frame can land at the start of a spin, but if it spreads over a matching pay symbol or wild, it triggers a Chain Reaction, placing a new Frame on that symbol, which can continue until the grid is filled.

Bonus Games
What we really looked forward to was landing multiple Sun Princess symbols (FS Scatters) on the grid to trigger the bonus games. Land 3 FS Scatters and you get Solaris Grove, 4 FS Scatters get you to Sunfire Palace, and, if you’re lucky enough to land 5 FS Scatters, welcome the Golden Eclipse!
The bonus games maintain the base game mechanics, but each adds an extra reward. So let’s first talk about similarities. Each bonus game kicks off with 10 free spins and landing 2 or 3 FS scatters awards an extra +2 or +4 free spins, respectively, extending the bonus game duration.

Now for the nuance. In the Solaris Grove, we saw a heightened chance of landing Sun Ray Frames with each spin. In the Sunfire Palace, if a Sun Ray Frame spreads through a Wild symbol, not only does the Wild symbol trigger a 2x multiplier, it gets sticky and remains on the grid throughout the bonus game, leading to constantly climbing multipliers! Now for the premiere Golden Eclipse. It keeps the functions of Sunfire Palace but doesn’t leave much to chance by guaranteeing at least one Sun Ray Frame per spin.

Bonus Buys
If you’re willing to up your stake, there’s a bunch of Bonus Buys you can activate:
- BonusHunt FeatureSpins (2x bet): This feature makes it 3 times more likely to trigger a bonus game.
- Stellar FeatureSpins (50x bet): This guarantees at least 1 Sun Ray Frame on each spin.
- Solaris Grove (80x bet): Directly buys into the Solaris Grove bonus game.
- Sunfire Palace (200x bet): Gets you a guaranteed entry into the Sunfire Palace.

Winning Strategies for Sun Princess Slot

We found that the game can seem dry and unrewarding if not played correctly. Once you’re familiar with the slot’s mechanics, focus on refining your strategy. The following are a few key strategies to keep in mind:
- Target Chain Reactions and Sticky Multiplier Wilds: We observed that Chain Reactions are critical because the game lacks cascading mechanics. Additionally, the way Wild symbols gain growable multipliers when hit by the spread makes their stickiness in the Sunfire Palace and Golden Eclipse bonus rounds something we'd recommend players aim for.
- Apply Bonus Buys: We observed that Bonus Buys can raise win possibilities exponentially, especially the pricier bonus game activators. We didn’t see the low-priced BonusHunt feature rewarding, but the rest can really be worth it.
All the Technical Details
Sun Princess operates on a 7x7 grid with wins formed by cluster pays by landing 5 or more matching symbols. The game runs on a medium volatility model with a maximum RTP of 96.29%. The bet range is 0.10 to 100. Payouts for low-value gem pieces range from 0.1x to 1x the bet for 5 matching symbols, while premium anime-type objects offer higher returns. The maximum win potential can reach 10,000x your bet. The game features a spreading mechanic and Chain Reactions.
Best Alternatives to the Sun Princess Slot
If you enjoyed Sun Princess, here are some other slots we think you might also enjoy:
- Starlight Princess by Pragmatic Play: A high-volatility slot thematically aligned with Sun Princess, featuring a dreamy anime world with bright jewels and vibrant symbols. Hosting a 5x6 grid and cascading mechanics, it delivers intense gameplay and the potential for a maximum 5000x payout.
- Sugar Rush 1000 by Pragmatic Play: Building on its predecessor, Sugar Rush 1000 is a vibrant and exciting slot hosting a 7x7 grid. The game features cluster pays but with the more conventional cascading features. The slot takes us into a more playful animated world than Sun Princess, but is similar in its feel good vibrance.
Our Verdict
Sun Princess is a cluster pay slot in a league of its own. It eliminates the traditional cascading features and introduces a range of unique mechanics, including bonus games, sticky Wilds, and more. Free spins are where the game shines, with increased Sun Ray Frame and sticky wild possibilities, the win potential goes through the roof!
However, we did note that as exciting as the game can be with special features, the base game is otherwise dull, making it almost necessary to purchase Bonus Buy features to keep oneself from falling asleep.
