Our content
The games, puzzles, text, graphics and code on bunsen.games belong to Bunsen. Scientific facts belong to everyone; our particular puzzles and how we present them are ours.
Accuracy
We work hard to keep every fact correct, but the games are made for fun and learning and are not a reference source. If you find an error, please tell us at hello@bunsen.games.
Stats and streaks
Your stats and streaks are saved in your browser. They can be lost if you clear your browser data, use a private window, or switch devices, and we can’t restore them.
Changes and availability
We may change, pause or retire games or features at any time. The site is provided “as is”, without guarantees that it will always be available or free of errors.
Liability
As far as the law allows, Bunsen is not liable for any loss arising from your use of the site. Nothing in these terms limits rights you have under consumer law that can’t be excluded.
Links and ads
The site may link to other websites and, in future, show ads from third parties. We aren’t responsible for their content or practices.
Changes to these terms
We may update these terms; the date at the top shows the latest version. Continuing to use the site after a change means you accept the new terms. Our privacy policy explains how we handle data.
