A dedicated contact email address will be published on this page shortly. We don't run a contact form, because we don't collect personal data on this site.
What to write to us about
- Corrections. If a lesson, guide or calculation looks wrong, tell us the page and what you expected. Accuracy matters more to us than anything else here.
- Bugs. Tell us the page, what you did, and your browser and device.
- Privacy questions. Use the same address. Note that we can't see or delete your training progress — it only exists in your browser. You can remove it yourself on the progress page.
What we can't help with
We can't give personal gambling, legal or financial advice, and we have no connection to any casino. If gambling is causing you problems, the responsible gambling page lists free, confidential help lines.
