This wikia is about the app 10 billion wives by Masukachi Inc. for Apple and Android devices, released on May 29, 2015. It is a casual game very similar to Cookie Clicker.
The goal of the game is to unlock each of the wives that can be purchased with Love. Love is earned over time by wives who provide a certain amount of LPS, or Love per second, depending on her initial LPS, her level and what presents the player has bought for her. The player can speed up the process of earning Love by tapping the screen. At the beginning of the game, you start out with 1 LPT, or Love per tap, but you can buy upgrades with Love later on. There are sixteen unlockable wives the player can marry and collect Love from.
The app currently has a rating 4.6/5 stars on the Google Play store, with over one million downloads and 150,000 positive reviews.
Leveling Up a Wife:
When you level up a wife, her LPS increases by a default amount for each wife (the LPS they gave at Lv. 1). Meaning, leveling a wife from Lv. 1 to 2 will yield the same increase as leveling that same wife from 99 to 100. The cost of her next level up will be ~113% of the previous cost.
