What it shows

• Today's position, from the side to move, with the last move marked.
• The goal (mate in 2, win material and so on) and the puzzle's rating.
• A Solve it button that opens the puzzle on ChessMess, where readers can play the moves on the board.
• A Show solution button for readers who just want the answer.

For dark pages, use /embed/daily-puzzle?theme=dark in the address; ?theme=light keeps it light. Past puzzles are in the daily puzzle archive, and new ones are in the RSS feed.

Questions and answers

Is the widget free?

Yes, on any website, including club, school and commercial sites. Please keep the small "Daily puzzle by ChessMess" line under it.

When does the puzzle change?

Every day at midnight UTC, at the same moment as the daily puzzle on ChessMess.

Does it track my visitors?

No. The widget has no ads and no analytics, and it doesn't set cookies. Like any web page, our server sees the request when the widget loads.

Can I change its size or colours?

It fits widths from about 280 to 400 pixels; 360 by 520 suits most sidebars. Add ?theme=dark or ?theme=light to the address to fix the colours. Without it, the widget follows the reader's light or dark setting.

Where do the puzzles come from?

From the Lichess puzzle database, which anyone may use (CC0). Each day's puzzle also has its own ChessMess page with the themes and the full solution.
