Based on a recent report from Sensor Tower (via GameSpot), Candy Crush is said to be averaging $4.2 million a day. The game in 2018 was reported to have made more than $1.5 billion in revenue from microtransactions across both iOS and Android devices. Given that this is a six year old franchise, no doubt this is a very impressive figure.
The original Candy Crush is also said to have made $945 million, and that 29% of spending valued around $443 million came from other spin-offs such as Candy Crush Soda Saga, while the Candy Crush Jelly Saga brought in $90 million. The latest title, Candy Crush Friends Saga, is said to have made about $3 million following its release back in October 2018.
As to how Candy Crush fares compared to the more recent competition, Pokemon GO was said to have earned $800 million in 2018, while Fortnite made about $445 million on iOS devices, so by comparison and considering how “old” Candy Crush is, it looks like it is still managing to hold its own.
