Bopline

A music guessing game for groups. A clip plays and you guess the year it came out — in Classic you can also name the song and artist for a bonus. Two modes.

CLASSIC
A clip plays with no title, artist or year shown. Place it on your timeline by release year. Naming the song or artist earns a bonus. First to enough correct placements wins. One phone passed around, or separate phones on a shared game code.

MASTERS
The host's phone shows a code. Everyone guesses the release year at the same time; a closer guess scores more. Players join either with the app or without it, at bopline.app/masters in a browser — no account, no purchase.

No music subscription needed. Songs play from Apple's 30-second previews.

TV or laptop: bopline.app/tv works as a shared game board.
