Puzzle Hub

About

Puzzle Hub is a free logic puzzle site — no accounts, no ads on the board, no tracking on the game screen. Sudoku and Kakuro are live; more logic puzzles arrive once the controller UX is solid.

Why this exists

Existing puzzle sites bury the actual game under signups, banner ads, and forced apps. Puzzle Hub keeps the path from open-the-page to first-input as short as possible — and treats one game well before adding the next.

Games

Sudoku and Kakuro, each with four difficulty profiles. Boards are produced by a seeded backtracking solver and verified to have a unique solution before being shown. Nonogram, Slitherlink, and other logic puzzles are on the roadmap.

How it works

The site is statically generated and uses no backend or database. Puzzles are produced in your browser by a seeded backtracking solver with technique-based difficulty rating — the seed in the URL is the only input, so the same seed always yields the same puzzle. Your language preference is stored only in your browser's localStorage; nothing is sent to any server.
