The idea is to create a clean, fast, and interactive experience where users connect letters around a box to form words with some added twists like daily challenges and streak tracking. ## Tech Stack So far, I’m thinking of: * Using `Next.js` (`App Router`) for the frontend * Deploying everything on `Vercel` for instant previews and scalability * Possibly adding `Edge Functions` for validating words in real-time From what I’ve seen, `Vercel` preview deployments are great for UI iteration, but they don’t fully simulate backend logic changes in previews — so I’m wondering how others handle full-stack testing for interactive games like this. ## Questions for the Community I’d love input on: * What’s the best way to structure game logic (client vs server)? * Any recommendations for handling a word dictionary efficiently? * Should I keep validation fully client-side for speed, or move it to `Serverless Functions`? * Has anyone built something similar (word/puzzle game) on `Vercel`? I’m especially interested in performance optimization and keeping the gameplay smooth across devices. Would really appreciate any insights, examples, or even repo links. Thanks!
