Sun Princess: Slot Overview
We’ve already encountered the Cloud Princess and the Rainbow Princess, and now another royal arrives to take the spotlight—quite literally—because this game is Sun Princess. It’s the latest entry in Hacksaw Gaming’s anime-styled slot lineup, built around cluster pays for forming wins. As expected from the studio, the experience leans heavily on spreading mechanics to keep things lively and deliver the big moments. Hacksaw Gaming is known for inventive design, so even if seasoned players feel they’ve seen enough spreading tricks, Sun Princess still manages to add a few fresh ideas alongside its bright, regal cartoon presentation.
Hacksaw Gaming’s princess-themed slots also tend to share dreamy, otherworldly backdrops, and Sun Princess follows that pattern. The base game plays out in a lush outdoor scene—something like palace steps or a picturesque garden corner where a princess can wander off and do princess things, whatever that entails. For this particular heroine, that means posing playfully in a more grounded setting, dressed in a barely-there outfit, topped with a golden crown, and looking cheerfully inviting.

The action takes place on a 7×7 gaming area, where symbols form winning clusters when at least 5 matching pay symbols connect vertically and/or horizontally. There aren’t any cascades when a win lands, but a Chain Reaction element ties directly into the spreading system, as explained below. The game runs on a medium volatile math model, and with stakes ranging from $/€0.10 to $/€100 per spin, the top RTP is 96.29%.
The paytable is split between 5 lower-value gem symbols and 5 higher-value princess-themed anime items. A cluster of 5 matching symbols pays 0.1x to 1x the bet, while covering the entire 49-tile grid with the same symbol returns 300x to 10,000x the bet. Wilds assist by substituting for all paying symbols. A full screen of wilds awards the same payout as the highest-paying symbol.
Sun Princess: Slot Features

The spreading comes from Sun Ray Frames, which can also generate multipliers in specific cases and set off Chain Reactions. On the bonus side, there are three rounds—Solaris Grove, Sunfire Palace, and Golden Eclipse—plus feature buys.
Sun Ray Frames & Chain Reaction
Sun Ray Frames can appear on pay symbols or wilds at the start of a spin and activate once wins have been checked. When they trigger, they spread in a straight line, transforming every symbol they pass over into the same symbol type as the original. Vertical rays expand upward and downward, horizontal rays move across the grid, and four-way rays push out in every direction until they reach the grid’s edge. After that, wins are evaluated again.
When a Sun Ray hits a wild, it applies a x2 multiplier to that wild, increasing by x2 each additional time it’s struck. If more than one multiplier is involved in the same win, they are added together before being applied. Only one Sun Ray Frame can land at the start of a spin. If a Sun Ray spreads onto a matching pay symbol or wild, it triggers a Chain Reaction by placing a new Frame on that symbol. This process can keep going until the grid becomes fully covered.
Solaris Grove Bonus Game
10 free spins start when 3 FS scatters land in the base game. The bonus uses the same rules as the base game, but with a greater chance of landing Sun Ray Frames. Across all bonus rounds, landing 2 or 3 FS scatters grants an extra +2 or +4 free spins, respectively.
Sunfire Palace Bonus Game
Landing 4 FS scatters in the base game activates this round and awards 10 free spins. Along with the Solaris Grove rules, this feature adds the following: when a Sun Ray Frame spreads through a wild symbol, that wild receives an x2 multiplier and becomes sticky on the grid until the bonus ends. The multiplier increases by x2 each time that wild is hit again by a Sun Ray Frame.
Golden Eclipse Hidden Epic Bonus Game
The Golden Eclipse hidden epic bonus game is triggered and awards 10 free spins when 5 FS scatters land in the base game. In addition to the Sunfire Palace mechanics, this round guarantees at least 1 Sun Ray Frame lands on every spin.
Feature Buys
This is where you’ll find BonusHunt FeatureSpins priced at 2x the bet, which makes spins 3 times more likely to trigger a bonus game, plus Stellar FeatureSpins that ensure at least 1 Sun Ray Frame appears on a spin for 50x the bet. Two bonus rounds can also be purchased: Solaris Grove and Sunfire Palace for 80x and 200x the bet, respectively.

Sun Princess: Slot Verdict
It’s no secret that Hacksaw Gaming enjoys making things spread across a grid in all sorts of ways, but Sun Princess pushes that idea further than usual. Here, symbols can expand left, right, up, down, and even in all four directions at once. A less ambitious developer might have stopped there, resulting in a simpler—though still good-looking—anime slot. Instead, Hacksaw Gaming layers extra effects on top, giving Sun Princess more complexity while also boosting the impact of the Sun Ray Frames.
The first major addition is Chain Reactions. That matters a lot in a game where only one Sun Ray Frame can land per spin and there’s no cascading mechanic—something that often pairs naturally with cluster pays. With Chain Reactions, spreads can branch into sequences of matching symbols shooting off in multiple directions. And since the top symbols can pay extremely high amounts, Chain Reactions become especially valuable. Another crucial element is how wilds can gain scalable multipliers when struck by the spread, which makes their stickiness during Sunfire Palace and Golden Eclipse even more important. Put together, these touches make Sun Princess more advanced than it may initially appear, and capable of reaching its 10,000x maximum in any mode.
Hacksaw Gaming’s original Cloud Princess slot felt slightly unusual in a catalogue that also included titles like Rotten, Cursed Seas, and Hand of Anubis. Then Rainbow Princess arrived to keep it company, followed by Aiko and the Wind Spirit. With three Princess slots now in the mix, the studio has clearly embraced the direction, and Sun Princess not only provides a charming anime world to spin through, but also takes a mechanic Hacksaw Gaming already loves and strengthens it with several clever upgrades.
