Kendall Jenner and Kylie Jenner are coming to Kim Kardashian’s popular freemium game “Kim Kardashian: Hollywood.” The 34-year-old reality-television star confirmed her younger sisters will be featured in the Glu Mobile Inc. title via an Instagram post Wednesday, although she didn’t reveal when Kendall, 19, or Kylie, 17, would appear.

“Kim Kardashian: Hollywood” launched last June. By November, more than 22.8 million players had downloaded the game and engaged in 1.2 billion-plus sessions, with more than 5.7 billion minutes played.

Users all begin at the bottom -- putting in long hours at a Hollywood clothing store -- and must work their way to the top by attending fancy parties and fashion shoots. The game’s addictive nature is partly due to its freemium business model, as players are essentially climbing the celebrity ladder alongside Kardashian. If they want to advance, they may have to fork over some real cash.

Last year, Glu Mobile predicted the game would earn $200 million by the end of this year. “Kim Kardashian: Hollywood” is free to download, but the in-app purchases can make it expensive. Leveling up, clothing and accessories can add to its cost. Even so, the app is still among the 40 most popular free games.

In February, Glu announced the game had pulled in $74.3 million last year. “Kim Kardashian: Hollywood” is available via the App Store (iOS) and the Google Play store.
