Kiloo and SYBO's 2012 endless runner Subway Surfers has taken in more than $80 million in revenue on iOS.

Sensor Tower reports that the title reached the milestone through in-app purchases alone. Revenue gained from in-game advertising isn’t counted in its estimates for the $80 million figure.

In the first half of 2018, Subway Surfers is said to have raked in $4.3 million in worldwide revenue on iOS.

Over half of this revenue came from the US, with the market there accounting for 51 per cent of player purchases. Great Britain followed in second with a 9 per cent share.

Subway Surfers has become a flagship title for Kiloo and SYBO receiving support and updates six years after launch.

The runner recently passed two billion total downloads and was the second-most downloaded game on the App Store between 2010 and 2018.
