RiddleNook makes free helpers for word games and free classic puzzles you can play in a browser: a five-letter word finder, word unscrambler, crossword solver and word search maker, plus sudoku, minesweeper and Klondike solitaire. Big, clear layouts, no sign-up, and nothing to install. Our word lists leave out slurs and other offensive words.
How our tools work
Every tool on RiddleNook runs inside your web browser. When you open a file, your own device does the work using built-in browser technology and WebAssembly. Nothing is uploaded, so the tools are fast, work with large files, and keep your files private.
Free, without sign-ups
You'll never need an account or an email address. The site is paid for by ads, which we keep out of the way of the tools themselves.
Who we are
RiddleNook is built and maintained by BlueEra. We'd love to hear which tool you'd like next, or about anything that doesn't work: get in touch.
