PlayForCalm (Logic-based Zen Arcade)
Project Overview: PlayForCalm is a minimalist web-based game suite designed to provide a “digital sanctuary.” The flagship project in this suite is a custom-built Sudoku Engine that focuses on clean aesthetics and focus-driven gameplay, free from the distractions of typical mobile games.
The Challenge (Problem): Most online puzzle games are cluttered with intrusive ads, aggressive color schemes, and “gamification” that actually increases stress instead of reducing it. Finding a high-quality Sudoku platform that is lightweight, offline-ready, and privacy-focused is surprisingly difficult.
The Solution (Engineering & Logic):
Custom Matrix Logic: Instead of using heavy libraries, I built a custom Sudoku Validation Engine using pure JavaScript logic to handle board generation, move validation, and difficulty scaling.
Minimalist UI (Zen Mode): Developed with React 19, focusing on a “Distraction-Free” interface. Utilizing soft shadows and muted tones to reduce eye strain during long sessions.
State Persistence: Implemented local state management so users can close their browser and return to their game exactly where they left off, without needing a database or account.

The Result: A lightweight, high-performance logic app that serves as a proof-of-concept for building focused, high-utility tools without the bloat of modern web clutter.
