How to use it
Copy the snippet for the widget you want.
Paste it into your page's HTML wherever you'd like it to appear (most CMS platforms have a "custom HTML" or "embed" block).
Publish. That's it — the widget loads live from our servers and stays up to date automatically.
Please keep a visible credit to Blackjack Odds Trainer. An unlinked text credit is welcome, and publishers may qualify any credit link with rel="nofollow" or another appropriate link attribute. The supplied snippets use branded, nofollow credits; a link that passes ranking credit is not required. The widgets are responsive, work on mobile, set no cookies, and run no ads.
Frequently asked questions
Is it really free?
Yes — completely free for any website, commercial or personal. Keep a visible branded credit, either as plain text or a link. Publishers may qualify the link; no followed link is required.
Will the chart stay accurate?
Always. The chart and calculator are generated live from our odds engine, so any improvement we make appears in your embed automatically — you never have to update the code.
Can I change the size?
Yes. Adjust the height and max-width values in the snippet to fit your layout. The widget is responsive and will fill the width you give it.
Does it slow down my page?
Barely — each widget is a lightweight iframe with loading="lazy", so it only loads when scrolled into view, and it sets no cookies or trackers.
