What is a 'refund if' offer?

A bookmaker promotion that refunds your stake (usually as a bonus) if a specific event happens during the game. Laying that trigger event on the exchange turns the refund into guaranteed value.

Why are there two lay stakes?

The first lays off the qualifying bet to fix a small loss; the second lays the trigger event so the retained refund value is captured whether the trigger happens or not.

What retention should I use?

Enter the share of the refund you expect to keep after working it, as a percentage. The refund's cash value in the maths is the max refund multiplied by that rate.

Radius

Default keeps the widget's own corners.

Accent, surface, text and radius are the only overridable tokens: a bounded set that keeps every widget readable. Fonts are stacks, so an embed never downloads one.

This rewrites itself as you change the controls above: font, colours and radius. It is exactly what renders the preview.

<div data-or-widget="refund-if"

<script src="https://oddsrelay.io/widgets/v1/oddsrelay-widgets.js" crossorigin="anonymous" async></script>

Paste it once, anywhere. The script auto-mounts every data-or-widget element and is style-isolated in a Shadow DOM, so it never clashes with your CSS.

Installing on WordPress, Webflow, Squarespace, Wix or React?

WordPress: Add a Custom HTML block (or switch the classic editor to the Text tab) and paste the snippet.
Webflow: Drop in an Embed element, paste the snippet, and publish. The widget renders on the published site.
Squarespace: Insert a Code block where you want the widget and paste the snippet as HTML.
Wix: Add an Embed HTML element (iFrame-free custom code) and paste the snippet.
Shopify: Paste into a Custom Liquid section (or theme.liquid for every page). A section keeps the widget on the one template you want it on.
React / Next.js: Render the div, then load the script once (e.g. next/script or an effect). The bundle auto-mounts new [data-or-widget] elements; call window.OddsRelay.scan() after client-side navigations if needed.

A 'refund if' offer pays money back when some condition happens — a sending-off, a 0-0, your team losing. Stage one is a normal qualifying back-and-lay that fixes a small loss. Stage two lays the trigger event so the retained refund value comes out as profit either way. Enter both stages and this calculator gives you the initial lay, the trigger lay and the guaranteed profit.
