About Minesweeper
Minesweeper was built for the moment you just need to handle this task and move on — no signup, no upload to a third-party server. Everything happens client-side, which means your files and data never leave your machine. The interface is intentionally minimal so you can focus on the task instead of learning the tool. Like everything else in the utility collection, it is free, ad-light, and works on mobile as well as desktop.
