What is crossword.by?

A no-frills site for crosswords, Sudoku, and logic puzzles in 7+ languages. Ad-free, instant, mobile-ready.

How does crossword.by handle multiple languages?

Modular word lists and validators per language — swap dictionaries, adjust for letter frequencies and clues.

Minimal JS, pre-rendered pages, SVG grids, aggressive caching. Loads in milliseconds, even on slow connections.

A solo dev's puzzle site loads faster than most newsletters. Here's the no-BS tech that made crossword.by a quiet rebellion against web slop.
