Kendall and Kylie Jenner
The 'Keeping Up with the Kardashians' stars only released 'Kendall & Kylie' yesterday (17.02.16) but it is already proving a hit with fans.
Taking to Instagram with a screengrab of the chart placing, Kylie wrote: "We are number 1 people!!!!!! #kendallkyliegame !!!!!! (sic)"
And the sisters' mother and manager, Kris Jenner, was equally delighted with the success of her "babies"' new venture.
She wrote: "Congrats to my 2 babies!! #1!!!! #proudmama!! thanks @glumobile for the amazing partnership! #kendallkyliegame.(sic)"
Similar to their older half-sister Kim Kardashian West's gaming app, 'Kim Kardashian: Hollywood', the two stars' game is an interactive experience where fans can create their own customised characters and interact with the famous family and their friends.
Users begin with no friends or job, just an iPhone and a tiny Santa Monica apartment and have to build their contacts list, reputation and embark on adventures throughout California.
The sisters are both avid users of social media, and it plays a key role in the game, as each time a player does something of note, they can post a selfie and gain followers within the virtual world's social media feed.
As more content is posted, users can unlock exclusive messages from Kendall, 20, and Kylie, 18, and gain likes and followers.
