What Is Sun Princess?

Sun Princess follows Celeste, an anime-styled Sun Princess, continuing Hacksaw's run of magical-girl aesthetic releases in the same visual family as Rainbow Princess. The presentation leans into warm, glowing golds and oranges befitting a solar theme, with a noticeably larger playing field than most of the studio's other cluster-pays titles.

The grid runs on a spacious 7-reel, 7-row layout using cluster pays, where 5 or more matching symbols connected horizontally or vertically form a win — one of the largest grids in Hacksaw's current catalog, giving Sun Ray Frames considerably more room to spread across.

Sun Ray Frames and Chain Reactions

How Sun Ray Frames Spread

Sun Ray Frames are the game's signature mechanic, spreading across the grid in up to four directions at once and transforming whatever symbols they pass through along the way. When a spreading frame makes contact with a Wild symbol, that Wild gains a x2 multiplier, and these multipliers stack further should additional Wilds be touched during the same sequence. A Chain Reaction can extend the effect considerably: whenever a Sun Ray Frame passes through a symbol that has a matching twin elsewhere on the grid, the frame spreads onward to that second symbol as well, letting one initial frame potentially cascade across a large portion of the 7x7 board.

Solaris Grove, Sunfire Palace and Golden Eclipse

Three scatters trigger Solaris Grove, ten free spins with a noticeably increased frequency of Sun Ray Frames appearing. Four scatters unlock Sunfire Palace, ten spins where Wild multipliers become sticky at their doubled x2 value rather than resetting, letting repeated frame contact compound considerably further across the round. Five scatters reveal Golden Eclipse, guaranteeing at least one Sun Ray Frame on every single spin — this mode is non-purchasable, reachable only through natural play. Landing 2 or 3 additional scatters during any mode adds 2 or 4 extra spins respectively.

Three feature buy options are available: Bonushunt FeatureSpins at 2x the bet, Stellar FeatureSpins at 50x, Solaris Grove at 80x, and Sunfire Palace at 200x — each offered across medium, high and very high volatility variants, letting players pick their preferred risk profile alongside the bonus mode itself.

RTP, Volatility and the Realistic Odds

Base game RTP is 96.29%, with the Bonushunt feature buy running slightly higher at 96.38% and the other bonus buy options ranging between 96.25% and 96.31%. Volatility is rated medium, a reasonable fit for a game whose spacious 7x7 grid already gives Sun Ray Frames plenty of natural room to chain without needing extreme volatility to compensate.

The 10,000x max win is most realistically chased through Sunfire Palace, where sticky doubled Wild multipliers give repeated Sun Ray Frame contact its best chance to compound across a full ten-spin round. Bets run £0.10 to £100 per spin.

Similar Slots Worth Exploring

Fans of Hacksaw's anime magical-girl catalog should also try Rainbow Princess, another cosmic-styled release from the same visual family, built around a more compact 6x5 grid instead. Players drawn to a spreading-frame mechanic specifically might also appreciate Le King's own Golden Squares system, applied to a very different Vegas setting.

Our Verdict

Sun Princess makes the most of its unusually large 7x7 grid, and the combination of spreading Sun Ray Frames with a genuine Chain Reaction mechanic gives the game a satisfying sense of scale that a smaller board simply couldn't replicate. Sunfire Palace's sticky doubled multipliers reward a longer bonus round nicely, and Golden Eclipse's guaranteed frame-per-spin structure gives the top bonus real consistency without an inflated buy price attached to it. Medium volatility keeps the whole package approachable, making this a solid pick for players drawn to the anime aesthetic who want steady, visually satisfying sessions.
