Disco is a free daily music puzzle that combines visual problem solving with music discovery. Each day, a single piece of album artwork is cut into tiles and shuffled, and a song is hidden behind the completed image. The primary function of the app is for users to swap the tiles to reconstruct the original picture, at which point the associated song is revealed and plays directly in the interface. The core workflow involves a single daily challenge that is identical for all users. Players solve the puzzle by swapping tiles, and the game tracks the number of swaps made. The goal is to use as few swaps as possible, with a "par" score representing the minimum number of moves required. Upon solving, links to the revealed song on various streaming services are provided. The service does not require users to create an account, and the daily puzzle format is intended for a brief, repeatable interaction. The project is currently live on Product Hunt, where it accepts community upvotes.
