Show HN: Jointter – A daily word puzzle using dots and lines

一位自称数学家的开发者在 Hacker News 发布了名为 Jointter 的每日文字解谜游戏，该作品灵感源自 Sudoku 和 Wordle 1。这款免费且无需注册的游戏可通过 https://www.jointter.com/ 访问，目前帖子热度较低，仅有 4 个积分且无评论 1。

Jointter 的核心机制是用三行点阵和连接线来表示拉丁字母，玩家需根据显示的点和线进行逻辑推理以猜出单词 1。其判定逻辑类似 Wordle：如果输入的单词线条或点与目标匹配则变绿，不匹配则变红，并新增红色点以提示非目标位置 1。

游戏的难度随星期递增，周一最简单（3个字母），周日最难（包含多于两个7个字母的单词）1。技术实现上，后端采用 Flask，算法由 Python 编写，而前端 JS/HTML/CSS 代码借助 AI 生成 1。

A mathematician has launched Jointter, a daily word puzzle game inspired by both Sudoku and Wordle, on the Hacker News "Show HN" forum 1. The core mechanic of the game involves representing Latin letters through a system of three rows of dots connected by lines, requiring players to deduce words based on these visual patterns rather than traditional letter inputs 1. Similar to Wordle’s feedback mechanism, Jointter turns green if the lines and dots of an input word match the target word, while mismatches turn red; additionally, new red dots appear to indicate points that are not part of the solution 1.

The difficulty of the puzzles varies throughout the week, starting with three-letter words on Mondays for the easiest challenge and progressing to Sunday’s hardest level, which includes more than two seven-letter words 1. The developer built the application using Flask for the backend and Python for the algorithms, while leveraging AI tools to generate the JavaScript, HTML, and CSS for the frontend 1. The game is accessible at https://www.jointter.com/, where it remains free to play without requiring user registration 1. At the time of the post, the submission had received four points and zero comments 1.
