Mystery Matters is a narrative-driven hidden object game played in portrait orientation. Players investigate detailed scenes by tapping to find clues and inventory items, which are used to solve environmental puzzles and advance the story.

The gameplay revolves around exploring interconnected locations, combining items, and deciphering codes from discovered documents. A hint system assists if progress stalls. The story unfolds through dialogue and collected case files.

Cases are presented episodically, with each offering a self-contained mystery to solve through observation and logical deduction. The touchscreen interface is designed for precise interaction with the game's intricate scenes and puzzles.
