Sources close to the situation tell TMZ the reality star will receive 45 percent of profits from the game, which is set to gross a reported $200 million on its first year. Kardashian's cut will reportedly be of $90 million and her expenses -- her agent, her mother Kris Jenner and taxes -- will not exceed $10 million.
Last year Kanye West's wife made a reported $28 million from all her business ventures, according to Forbes.
The new game, which allows players to pick different outfits and hairstyles and to "hit the hottest clubs, flirt and fall in love" in an effort to "make the A-list" will require users to pay real money for the items that will get them to the top.
Kardashian first introduced the app in an Instagram post in June.
