Ruby C, writing for NME, describes "Gambler" as a departure "from the group's usual (and predictable) title-as-a-repetitive-hook formula to create an alluring and unadulteratedly fun song". For the track "Secrets", she also wrote that, "it could have fit right in with [All About Luv's] pop sensibilities, sax outro, and mildly suggestive lyrics".
