Reality TV stars Kendall Jenner and Kylie Jenner have followed in the footsteps of their older half-sibling Kim Kardashian by creating their own mobile game.

Kendall and Kylie, aged 19 and 17 respectively, have announced they are developing an application based on their own lives, reports femalefirst.co.uk. "We couldn't wait to tell you any longer! Excited to announce that we are working on our own mobile game! #KendallKylieGame #staytuned (sic)," Kendall wrote on her photo-sharing website Instagram account.

Last year, Kim, 34, launched her own game for mobile phones, "Kim Kardashian: Hollywood", in which players can pretend to be a rising celebrity pal of the reality TV star. The news comes just a fortnight after the two youngest "Keeping Up with the Kardashians" sisters were added to Kim's game, which has been downloaded more than 23 million times and made around $74 million in 2014.
