Moon Princess fills a 5×5 grid with symbols. Winning groups vanish and replacements drop down; each successive drop can increase the win multiplier. The three princesses change losing rounds in different ways: Love transforms symbols, Star adds Wilds, and Storm removes symbols.

Matching symbols charge the Princess Trinity meter for a combined re-spin. Clearing all 25 positions opens the free-spin sequence, where the chosen heroine's ability matters. The feature differs from Reactoonz's alien clusters because the princess powers and full-grid clear set the pace of a round.
