Is Sudoku100 free on every platform?
Yes. Every product — mobile app, browser extension, AI/MCP, and developer API — is free to use. Optional Membership removes ads and unlocks unlimited hints anywhere.

Can I use Sudoku100 inside ChatGPT or Claude?

Can I embed Sudoku100 on my own website or blog?
Yes. Use the image API for static puzzles, the iframe embed for interactive play, or our WordPress-style shortcode. See the Developer API page for details.
