箱中少女 (also known as "Girl in the Box") is an Android game developed by 沙漏工作室. In this game, players take on the role of a college student who unexpectedly encounters a talking "box" on the street. Little did they know that inside this box lies a surprising secret...

The game offers several unique features to enhance the gameplay experience. Players can easily interact with the game by simply tapping to collect rewards. Additionally, there is an option for automatic collection to reduce the burden of gameplay. At the end of each round, players can also look forward to unexpected rewards to accelerate their progress.

箱中少女 not only focuses on the main storyline but also provides opportunities to pursue romantic relationships with other characters, such as the school beauty and senior schoolmate. Each character has their own rich and engaging storyline to explore.

Furthermore, the game features a collection system where players can gradually collect and view stories of their girlfriend and other characters.

The best part is that 箱中少女 is completely free to play. There is no need for in-app purchases or gacha systems. Players can unlock various functionalities by simply watching videos. (And for those who prefer an ad-free experience, there is an option to remove ads!)

Please note that this game is classified as suitable for players aged 15 and above according to the game software grading management regulations. It is also important to mention that while the game is free to use, it does include video ads and banner advertisements. However, there is an option to remove ads through a paid feature.
