Sun Princess

By Becky M. | Updated 24 October 2025

Sun Princess is a video slot developed by Hacksaw Gaming, released on 23rd October 2025. It marks a new chapter for Hacksaw Gaming, a studio renowned for its moody, comic-book signature style. This time, they have embraced a radiant anime-style aesthetic bursting with golden light and celestial charm. It is played across a 7×7 grid with cluster pays and glowing “Sun Ray Frames” that ignite chain reactions. The slot features Hacksaw Gaming’s familiar mechanics with an entirely fresh face. It’s elegant and unlike anything the studio has produced previously – a celestial curveball that proves Hacksaw’s darkest hearts have room to shine.

Technical Features

Sun Princess features a 7×7 grid with a cluster win mechanic: 5 or more matching symbols trigger a cascade. The game has an above-average RTP of 96.29%, while the 47% hit rate suggests steady activity throughout. The slot has medium volatility with a max win capped at 10,000x the bet per spin. Sun Princess is available on desktop and mobile devices from 10p to £100 per spin; however, the max bet per spin in the UK is capped at £5.

Design and Symbols

The Sun Princess rules over the realm and glows beneath perpetual daylight. Marble paths wind through gardens thick with emerald leaves and golden blooms. Every surface reflects the warmth of the sun, from the shining arches above to the white stairs leading to the princess’s radiant palace. A soft melody of harps and strings drifts through the air, giving the scene a calm that feels almost sacred. At the centre of it all lies the 7×7 reel grid, suspended within a transparent frame that seems to pulse with light, where matching clusters must form to earn the princess’s favour.

Low-value symbols are the deep green, ocean blue, royal purple, amber, and crimson gems, awarding between 0.1x and. 1x the bet for 5 of a kind. The higher-paying symbols are the brooch shaped like a sunburst, a wide-brimmed hat trimmed in gold, a delicate porcelain vase, a glowing orb of light, and a jewelled tiara. 5 matching symbols in a cluster award between 0.1x and 1x, but a full grid of matching high values award between 300x and 10,000x the bet. The Wild appears as a glowing green “W” woven in vines, and substitutes for regular symbols. The Sun Princess is the Scatter.

Features Overview

Hacksaw’s Sun Princess features Sun Ray Frames, Chain Reaction, Solaris Grove Bonus, Sunfire Palace Bonus, Golden Eclipse Hidden Epic Bonus, and a Feature Buy (not available in the UK).

Sun Ray Frames

Sun Ray Frames can land in any position on the 7×7 grid. They are marked with arrows that determine which way their light will travel – vertically, horizontally, or in all four directions. After any wins are evaluated, the frame triggers and sends beams of light through the grid, transforming every symbol it touches into the same symbol it initially appeared on. If the beam of light passes over a Wild, the Wild remains sticky and receives a 2x multiplier. If more than one frame hits the same Wild, the multiplier increases by 2x.

Chain Reaction

If a Sun Ray beam crosses a symbol that matches the one it originally landed on, a Chain Reaction triggers. A new frame appears in that position and its beams spread across the grid. The process continues if new matching symbols are formed, or until the entire grid is filled with matching symbols.

Solaris Grove Bonus

The Solaris Grove Bonus Game triggers when three Scatters appear in the base game, awarding ten free spins. The feature plays the same as the base game, but with a higher frequency of Sun Ray Frames appearing on the grid. During the bonus, landing two or three additional Scatters awards between +2 and +4 extra spins, extending the round and increasing the potential for those luminous chain reactions to unfold.

Sunfire Palace Bonus

The Sunfire Palace Bonus Game triggers with four Scatters during the base game, awarding ten free spins. It follows the same structure as the Solaris Grove feature but introduces sticky Wild multipliers. When a Sun Ray beam passes through a Wild, it gains a 2x multiplier and remains sticky for the remainder of the round. Each time the same Wild is struck again, its multiplier increases by 2x, allowing the grid to build layers of glowing, multiplier-charged symbols as the spins progress.

Golden Eclipse Hidden Epic Bonus

The Golden Eclipse Hidden Epic Bonus Game triggers with 5 Scatters in the base game, unlocking ten free spins. It builds on the Sunfire Palace rules, retaining sticky Wild multipliers, but at least one Sun Ray Frame is guaranteed to appear on every spin.

Feature Buy-In (Feature Buy is not available in the UK.)

The Feature Buy menu allows players to buy into the special features for an additional cost:

2× – Bonushunt Featurespins – Three times more likely to trigger a bonus.

50× – Stellar Featurespins – Guarantees at least one Sun Ray Frame on every spin.

80× – Solaris Grove Bonus – awarding 10 free spins.

200× – Sunfire Palace Bonus – awarding 10 free spins.

Conclusion

Sun Princess, developed by Hacksaw Gaming, is one of the studio’s most striking releases in its ‘Princess’ series. It combines a rich anime-inspired theme with unique mechanics that keep the action flowing. The Sun Ray Frames power the game, illuminating the 7×7 grid with transforming symbols and increasing multipliers. The three progressive bonus rounds build momentum. The 10,000x max win combined with a bright, energetic presentation, Sun Princess is a confident entry in Hacksaw Gaming’s Princess series – refined, rewarding, and built to impress.
