Each one is seven songs, one second at a time. Pick a decade or a genre, or play the daily puzzle that everyone in the world gets at the same time.
You hear one second of a song and choose the title from four options. Listening longer — two, four or eight seconds — is allowed and costs points. Previews come straight from Apple iTunes, so it is always the real recording. Nothing is stored and no account is needed.
The full game is FlipList on Android: 40+ playlists, 200 solo levels across 20 hand-painted worlds, and a daily streak worth keeping.
