Virgulando is an Android game developed by Mambee Lab that aims to simplify the complex rules of comma usage and make it easier for users to understand and implement in their writing. The game provides an introduction to the importance of commas and the type of pause they require. It offers various interactive activities that cover the main rules of comma usage, all set in a dynamic classroom environment complete with a projector and other resources.

One of the unique features of Virgulando is the use of sound to analyze pauses that can alter the meaning of a sentence, depending on the presence or absence of a comma. The game also includes fun exercises that review the main uses of commas and offer additional learning opportunities. The project was created by Marlange Benvinda dos Santos Brito as part of her Master's thesis in Letras-PROFLETRAS/UESPI/CAPES.

The game's programming and art were done by Weliton Sousa Araujo, and the voices were provided by professional voice actors. The game uses materials from credible sources to provide users with accurate and relevant information about comma usage.
