Speedy sequel Temple Run 2 has notched up more than 20 million downloads on the App Store in its first four days on sale, winning it the top spot on the charts for free iOS apps after just eight hours.
"The response from fans has been overwhelming," said Imangi co-founder Keith Shepherd.
"We are thrilled players want more of the Temple Run universe, and we hope to grow and expand the game over the coming months."
The free game was released on January 17, and is also number 3 in the Top Grossing Apps chart. Imangi also reports that the game has already seen 210 million sessions, resulting in around 1,775 years of gameplay.
It's predecessor, Temple Run, which was released in August 2011 has now been downloaded 170 million times from the App Store, Google Play and the Amazon Marketplace.
Last October Imangi revealed a two-year partnership with monetisation solution provider W3i.
