Show HN: One More Letter is a new browser-based word game launched on Hacker News. The project, accessible at playonemoreletter.com, challenges players to build words by adding a single letter at a time. The minimalist interface focuses on quick, iterative gameplay that tests vocabulary and pattern recognition.

The game mechanics are straightforward: starting from a seed word, each turn requires appending one letter to form a new valid word. This constraint creates a puzzle-like progression where strategic letter choice determines how long a chain can continue. No accounts or downloads are required, emphasizing immediate accessibility.

The Hacker News submission garnered 17 points and 13 comments, indicating modest early interest from the community. Discussion threads explore potential features like multiplayer modes, daily challenges, and mobile optimization. The developer has not yet disclosed technical stack or monetization plans.
