bitlife refers to an online multiplayer version of the popular life simulation game BitLife. Originally, bitlife online is a single-player game where you simulate the life of a character by making decisions that affect their happiness, health, wealth, and overall life journey. The game involves making choices like choosing a career, getting married, having children, and more, all of which affect the outcome of the simulated life.

In BitLife Online, the game expands on this concept by introducing online multiplayer features. Players can now interact with others, potentially competing or cooperating in different life scenarios, creating a more social experience compared to the original version. BitLife Online includes social features such as:

1. Multiplayer Mode: Play with or against others in real-time.
2. Challenges: Compete in various in-game challenges with other players.
3. Shared Worlds: Join shared "worlds" or "servers" where you can live out your life and interact with others.
4. Social Features: Communicate, collaborate, or compete with friends and players around the world.
5. New Game Mechanics: There may be special features unique to the online version, such as events or community-driven activities.

However, BitLife Online may not be available as a standalone app and could be integrated into the original BitLife app, requiring an internet connection to access multiplayer features.

If you're looking to play or learn more about BitLife Online, I recommend checking the official app store listing for BitLife or their website for the latest updates and access options.
