White Girl is presented as a real-time strategy, but with a unique mechanic where you need to constantly change colors in the right sequence to win. The colors represent combat states that are used during battles and display what is happening on the battlefield. Multiplayer mode is supported for up to 4 participants per server. A local server can also be created where players jointly complete tasks or fight each other.

The plot centers on girls created on the basis of artificial intelligence. Acting and studying the environment, everything appears to them as colors. Such a practice helps the girls become human or be indistinguishable from them. There are three statuses that are in constant change: R, G and B. Their main task is to get a value of 255 in each parameter in order to achieve their own goal. If they succeed in doing this, they will become white, both internally and externally.

The gameplay is presented as a royal battle, where gradually there is less and less time for the match. The world battle creates a session with random players, you can also create your own lobby to invite certain people. Before passing, you can customize the girl to your taste, changing dozens of parameters of her appearance. Participating in matches and completing tasks, more cosmetic items are opened.
