3DS Random Game Launcher is a Nintendo 3DS homebrew application that randomly selects, displays and then launches an installed game from the SD card. It scans installed titles, filters out system applications, and picks a random game to launch.

The title database contains 4,135+ 3DS game entries with title IDs and names, sourced from the 3dsdb community database.

Originally created by einso as a proof-of-concept, it was later expanded by selloa with improved error handling, title filtering, and additional features. The project uses code from the devkitPro 3ds-examples app_launch template.
