Puzzle Quest: Galactrix for Nintendo DS is a unique blend of sci-fi and puzzle genre elements. This match-three game evolves the concept by introducing a hexagonal grid and a gravity mechanic that alters gem direction based on the board's orientation in space. Players engage in battles, hacking, and mining by matching colored gems to power ships and skills. It combines RPG elements such as story, character progression, and side quests with deep strategy, providing a rich and immersive experience that expands the boundaries of traditional puzzle games.
