Alma released her debut extended play Dye My Hair in 2016. In 2017, she was featured on Sub Focus' single "Don't You Feel It" and Martin Solveig's single "All Stars" and released solo singles "Chasing Highs" and "Phases" with French Montana. In February 2018, it was announced that Alma would release Heavy Rules Mixtape the following month.^[2] Alma said that she decided to release more music, because "I’m going on tour and I have these festival shows and everything, and it feels super horrible to play these gigs and to have so few songs out".^[4] In an interview with Paper, Alma spoke of the recording process, saying:

I think now I've found what I want to do — I've found my friends and the people I like to work with. While I was once struggling with my sound, I'm in a better place than when I started. You can hear the vibe on this mixtape, too.^[5]

Heavy Rules Mixtape received positive reception from Idolator, according to which "it goes hard from the opening track and maintains that quality and energy until the final beat"^[6] Paper wrote of the release that it is "full-on pop, packed with slick club synths and smart lyrics that build into enormous choruses".^[5] Nylon wrote that the EP is "one of the finest releases to come out of the pop scene" in 2018.^[7] Finnish newspaper Helsingin Sanomat gave the release four stars.^[1]
