In an interview with Complex, Latto said that she was experimenting with various sounds and genres on the album to showcase her versatility, including pop, R&B, trap, and rhythmic vibes.

[7] The third single of the album, titled "Wheelie", featuring a guest appearances from an Atlanta-based rapper 21 Savage, was released on March 11, 2022.

[8] "Sunshine", featuring a guest appearances from fellow American rappers Lil Wayne and Childish Gambino, impacted US rhythmic contemporary radio as the album's fourth and final single on April 26.

[9] AllMusic wrote that Latto covers "the standard range of topics" such as "bedroom bragging" on "Wheelie" and "getting money and demolishing enemies" on "Trust No Bitch".

[10] Writing for Clash, Ana Lamond felt that "the tracklist weaves through Big Latto, the signature hard-hitting persona, whilst turning to the more sensual, R&B production that lends itself to a vulnerability" and "there's a sense that the riser is leaning into an increasingly diverse approach, welcoming a pop-centric commercial appeal", adding that "777 is daring and ambitious, paving the way for Latto's fortunes as she embraces the spheres outside of Atlanta rap" and "at the end of the day, she's got it tatted on her wrist...".

[11] Jordan Bassett of NME opined that "away from the Billboard-bothering singles, Alyssa Stephens [referring to Latto by her real name] dials down the braggadocio and dials up the introspection, though the overall mood is buoyant" and "it's a record that meets Stephens on the other side of criticism that has dogged her since she introduced her unintentionally offensive former moniker, Mulatto, as an eventual winner of reality show The Rap Game in 2016".

[12] Pitchfork music critic Tyra Nicole Triche stated that "777 proves that Latto is a formidable force, though there's still work to do to realize her full potential" and "if she hasn't quite nailed down a winning sound, she's willing to take some big gambles".
