NoFoMo: Attention Game is a Chrome add-on designed to help users combat digital distractions by challenging them to stay focused on a single tab. The game encourages users to set a timer and engage in a challenge where they must avoid switching to other tabs or windows. The primary goal is to maintain concentration on one page, enhancing productivity and focus during browsing sessions.

The game also features a "High Stakes Mode" for those seeking an extra challenge; if players lose, a randomly selected open tab will be closed. NoFoMo does not block tabs or windows, instead tracking when users get distracted, making it a practical tool for anyone looking to improve their focus in a multitasking digital environment.
