If something felt confusing, a value looked wrong, or the game did not behave on your device, please tell us. A short, specific note is genuinely useful.
Reporting a factual correction
Include the prompt, the answer shown, the value you expected, and a reliable source. Rounded values can differ between sources without either source being careless, so the exact measurement method helps us review the report fairly.
Reporting a technical problem
Tell us your browser, device, approximate screen size, the page you were using and what happened just before the issue. A screenshot is welcome, but never send passwords, private account data or anything confidential.
