ABOUT NOVA SUDOKU
A modern Sudoku space for playing, learning and connecting
Nova Sudoku is designed to help players start quickly, learn rules while solving, explore multiple variants, print puzzles and challenge friends.
What makes it different
Eight variants, six difficulty levels, contextual tips, Daily Challenge, Printable Studio, offline PWA support and multiplayer rooms for 2–8 players.
Transparent benefit claims
Sudoku can be used as an activity for practising logic, attention and working memory. Nova Sudoku does not diagnose, treat or guarantee an IQ increase. Puzzle IQ is only an in-game achievement score.
Technology
The app uses Next.js App Router, TypeScript and React. Personal progress is stored in the browser, while multiplayer rooms can use Redis in production.
