Underneath the anime charm lies a well-balanced slot filled with innovative features like Sun Ray Frames, Chain Reactions, and three powerful bonus games: Solaris Grove, Sunfire Palace, and the mysterious Golden Eclipse.
Whether you’re drawn in by its glowing visuals or the promise of a 10,000x max win, Sun Princess represents Hacksaw Gaming at its most confident — bold, playful, and polished.

What Makes This Version Different?
We’re no strangers to Hacksaw Gaming’s anime slots — we’ve had encounters with both “Cloud Princess” and “Rainbow Princess” in October 2024 and August 2025.
This time, Hacksaw Gaming has gone bigger and better, extending the grid from a 6×5 to a symmetrical 7×7.
Like the recently released Rainbow Princess, Cluster paylines are used once more, and there’s a max win shared by all three of 10,000x. Volatility remains unchanged, with a medium risk rating, although the high frequency increases to approximately 47%.
Put simply, it’s a bigger, better version of the anime titles that precede it.

Slot Mechanics
Sun Princess offers the biggest grid of all previous “Princess” titles from Hacksaw Gaming — a 7×7 grid offering a whopping 49 symbol spaces.
Winning combinations are paid out with a cluster system—meaning five or more identical, touching symbols will pay out.
Vertical, horizontal, and four-way Sun Ray frames can land on a low-paying, high-paying, or Wild symbol at the start of a spin:
- Vertical Sun Ray Frame: Spreads from the symbol it landed on vertically to either edge of the grid.
- Horizontal Sun Ray Frame: Spreads from the symbol it landed on horizontally to either edge of the grid.
- Four-way Sun Ray Frame: Spreads from the symbol it landed on both vertically and horizontally to either edge of the grid.
After spreading, new wins are awarded from the newly formed clusters. If the spread moves over a wild symbol, a 2x multiplier is added to the wild, multiplying the win.
A “Chain Reaction” can occur if a Sun Ray Frame spreads over a symbol of the same type that the Sun Ray landed on. A new Sun Ray Frame will then spread from the second symbol. This can continue until the entire grid is full.
Bonuses and Feature Buys
Sun Princess offers four different Bonus Buy’s, starting from 2x bet and extending to 200x bet:
- Bonus Hunt Featurespins: Each spin is 3x more likely to trigger a bonus game
- Stellar Featurespins: At least 1 Sun Ray Frame per spin
- Solaris Grove: 10 free spins with an improved chance of Sun Ray Frames – can also be triggered by landing 3 FS scatter symbols at the same time.
- Sunfire Palace: 10 free spins with Sticky Wild Multipliers – can also be triggered by landing 4 FS scatter symbols at the same time.
Sun Princess also boasts a Hidden Epic Bonus — the Golden Eclipse game.
This can be activated by landing 5 FS scatter symbols during a single round to earn 10 free spins. The Sticky Wild Multipliers from the Sunfire Palace game remain, but this time, there’s a minimum of 1 Sun Ray Frame guaranteed on every spin!
RTP and Volatility
The theoretical return to player (RTP) for Sun Princess is 96.29%. This changes to 96.38% with the Bonus Hunt Featurespins, 96.30% with the Stellar Featurespins, 96.25% when playing the Solaris Grove bonus game, and 96.31% when playing the Sunfire Palace bonus game.
Volatility is medium (6/10) with a maximum win of 10,000x. Overall, the game is well-balanced, best suited to casual players.
Final Thoughts
Hacksaw Gaming’s latest anime-themed slot, Sun Princess, is a fantastic addition to the Princess lineup.
A large 7×7 play grid feels enormous compared to the earlier titles, and there are just enough features and bonus games to keep players on their toes. Fans of super feature-dense games may find the title a little underwhelming, but it’s perfect for easy playing.
A high base RTP of 96.29%, medium volatility, and a 10,000x max win make this fantastic for casual players to enjoy. It’s a real lazy Sunday kind of game with a killer theme and great gameplay.
You can find this new slot at top sweepstakes casinos, many of which offer generous sweeps promo codes for new users.
