Timeline. Everyone starts with one song card showing its year. On your turn a mystery song plays. Tap where it fits in your timeline: before, between or after your cards. Get it right and you keep the card. The first to collect the target number of cards wins.
Guess the year. A song plays and everyone guesses the year it came out. Exact year scores 3 points, within 2 years scores 2, within 5 years scores 1. Most points after the last round wins.
Music. Each song plays as a 30-second clip with the title hidden until the guesses are in. No account needed, just an internet connection.
