Borble

Name the anime from its opening.

You start with half a second of the song and six tries to place it. Miss, or skip, and the clip grows: one second, two, four, eight, sixteen. All players get the same opening that day.

Play it with the channel.

Launch Borble in a channel and it posts who is playing and how far each of them has got, updating as you go. Nobody sees anyone else's guesses, so nothing gets spoiled. View other player's progress in the app as you go.

Any title counts.

ype the show in English or romaji, or take it from the list.

Link your shows.

Connect a public MyAnimeList and the reveal shows who else in the server has the show on theirs.
