In 1974, the band The Meeples broke up during the recordings for the "Vinil" album. The A-side of the unfinished album quickly became cult-followed by fans and critics around the world, turning into one of the most intriguing legends of rock-and-roll history. Fifty years later, the band has finally reunited to finish the B-side with the help of a team of the best musical producers in show biz. That's you!

In HiFi, players start their turn by spinning the record's rondel on the turntable to choose an action within their reach, or they can spend production points to achieve one of the other actions. After resolving these actions, players allocate audio cards to the five studio tracks, earning points based on the buttons in that producer's equalization track and what's in the studio track. When a player allocates a guitarist card, each player who collaborated with the equalization of the guitar earns points. When elements such as sound wave or time-track positions match, players can perform bonus actions.

Each round represents a song recorded on the A-side of the album that will help players gather information to aid B-side recordings. After listening to all of the songs on the A-side — 6-8 rounds depending on the player count — the game ends. Whoever contributed most effectively to the construction of the tracks on the album's B-side wins.
