Ludo King`, a mobile game version of the classic board game, became one of the most successful games in India and internationally, with over half a billion players. The game's success was made possible by MongoDB Atlas, a global cloud database service, which provided the necessary scalability and flexibility to manage the game's growth. Gametion, the company behind Ludo King, chose MongoDB Atlas for its ease of use and integration into their Node.js architecture, allowing them to focus on developing new features without worrying about database administration. With MongoDB Atlas, Gametion was able to efficiently manage hundreds of millions of users and support rapid growth, including a 1,000% increase in players during the COVID-19 lockdown. The game's success showcases the capabilities of MongoDB Atlas as a platform that can help businesses scale and innovate without sacrificing performance or reliability.
