Mobile titles Temple Run and Temple Run 2 have collectively hit the one billion downloads milestone, according to developer Imangi Studios.
"Having Temple Run reach the one billion downloads mark is a milestone we couldn't have imagined when we first started out," said studio co-founder Keith Shepherd.
"We're incredibly grateful to all the Temple Run players and our wonderful team. We look forward to continuing to grow the Temple Run franchise, as well as creating additional innovative games."
Over 32 billion games have been played, which equates to 216,018 years of play by gamers and 50 trillion metres of in-game running.
Temple Run 2 achieved more than 20 million downloads on the App Store in its first four days on sale when it was released in January 2013.
The original Temple Run was first released in 2011 and since the series has seen movie themed spin offs Temple Run: Brave and Temple Run: Oz, which are not included in the milestone.
