Supercell's Clash of Clans saw a year-over-year revenue increase in 2019 for the first time since 2015, thanks at least in part to the introduction of a "Gold Pass" reminiscent of Fortnite's "Battle Pass."
According to Sensor Tower, Clash of Clans brought in $727 million in total revenue for 2019, up 27% year-over-year from $527 million in 2018. Prior to that, yearly revenue had been on the decline since its last year-over-year increase in 2015, when Clash of Clans brought in $1.8 billion -- up 9% year-over-year from 2014's $1.6 billion.
Sensor Tower suggests this is due to the introduction of a $4.99 "Gold Pass" of content beginning in April, noting that spending that month went up 73% year-over-year, 58% month-over-month from March, and reached $66.6 million. In the first seven days after the Gold Pass release, spending shot up 145% and reached $3.9 million per day during that period.
Clash of Clans has been out since 2012, and in 2019 accounted for 42% of developer Supercell's total revenue. Total since its launch, it's brought in over $6.4 billion worldwide.
