Hi HN,

I built Slitherlinks.com — a site to play Slitherlink puzzles (also known as “Loops” or 数回) in the browser.

Some features: • Daily puzzles with varying difficulty (easy → hard). • Multiple grid sizes: 5×5 up to 15×15. • Accounts, trophies, and leaderboards if you like competition. • Simple interactions: click to draw/erase a line, right-click (or Ctrl+click) to mark an edge with ×. • Tech stack: Next.js + TypeScript + PostgreSQL + Phaser.js, responsive design (desktop & mobile).

I enjoy logic puzzles a lot, so I wanted to create a smoother, more accessible Slitherlink experience. This is my first time sharing it here, and I’d really appreciate your feedback: • Is the UI/UX intuitive? • How is the mobile experience? • Any features you think are missing?

Try it here: https://slitherlinks.com

Thanks!
