The short answers to what people actually ask about LyricLock.
Yes — the daily puzzle and Speed Blitz are both free. Vinyls (power-ups) and optional Music Packs can be bought in the Shop, but nothing is required to play.
Guessing on line 1 earns 400 points, line 2 earns 300, line 3 earns 200, and line 4 earns 100. Miss all four lines and you get zero for the day — but there's always tomorrow.
Missing a day breaks your streak unless you have a free pass saved up. Every past puzzle — the date, song, artist, and how many players got it right — is logged in the Puzzle Archive, so you can always look up what you missed.
Daily is one puzzle a day, the same song for everyone. Speed Blitz is a 60-second sprint to identify as many songs as you can, with combo multipliers for consecutive correct answers. Music Packs are on-demand genre libraries you can play anytime, not just once a day. See the full rundown, plus scoring and badges, on the About page.
