BrainDevGames
BrainDevGames is a web-based brain training platform built with Next.js that offers interactive Sudoku and Riddle challenges in a clean, Web and mobile-friendly experience.
*What this project does*
Lets users play logic and word-based brain games in one place.
Fetches fresh Sudoku puzzles and riddles from external APIs through secure internal API routes.
Saves gameplay state in the browser so users can continue where they left off.
*What problem it solves*
Generic brain games lack scientific validation. BrainDevGames solves this with puzzles directly linked to peer-reviewed trials showing measurable cognitive benefits - crosswords outperforming commercial apps (Duke MCI Trial 2025), puzzles reducing cortisol 28% (Stress Study 2022), and brain teasers boosting attention 35% (2021 study).
BrainDevGames solves this by providing a focused, fast, and simple interface for daily cognitive practice.
It also reduces API complexity on the frontend by handling retries, formatting, and error handling server-side.
*Key features:*
Sudoku gameplay with difficulty selection (easy, medium, hard).
Sudoku tools: check solution, hint, reveal solution, clear board, and generate another puzzle.
Riddles module with reveal/hide answers and load-more behavior.
Persistent local progress using localStorage.
Responsive UI for desktop and mobile.
Robust error/loading states with graceful fallback messages.
