Found a mistake, hit a bug, or have an idea for a game? We read every message.
Reporting a bug
It helps a lot if you include:
- the game and puzzle number (shown next to the game’s name, for example #12)
- your device and browser, for example “iPhone, Safari” or “Windows laptop, Chrome”
- what you did and what went wrong; a screenshot is perfect
A wrong fact
Tell us which element, date or fact looks wrong and, if you can, where you checked it. Corrections go in as soon as we’ve confirmed them.
Teachers
You’re welcome to use Bunsen in class, no sign-up needed: share the link and everyone gets the same puzzle that day. We’d love to hear how it goes.
