Lay a first-goalscorer scorer promo and see the profit if your player scores again.

DD/HH calculator widget

Design: font, colours, radius

Font

Inherit the font of the page it sits on.

Colours

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.

Embed code

Embed codeLive

This rewrites itself as you change the controls above: font, colours and radius. Copy it from the button under the code.

index.html

<div data-or-widget="dd-hh"
     data-or-theme="midnight"
     data-or-font="host"></div>
<script src="https://oddsrelay.io/widgets/v1/oddsrelay-widgets.js" crossorigin="anonymous" async></script>

Copy this and paste it on your site.

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.

Double Delight and Hat-trick Heaven offers pay enhanced winnings when your first goalscorer scores again: doubled if they score twice, tripled for a hat-trick. Back the player as first scorer at the bookmaker, lay them at the exchange, and this calculator sizes the lay and shows every outcome.

What it does

Lay stake, liability and back/lay rating
The qualifying loss if the player simply scores first
The windfall profit if the bonus doubles or trebles the winnings
One tap to copy the lay stake

How to use it

1Enter the bet. Type the back stake, exchange commission and the back and lay odds for the first-goalscorer market.
2Read the lay. See the lay stake, liability and qualifying loss for a standard first-scorer result.
3Check the windfall. See the profit if the promotion pays double (a second goal) or treble (a hat-trick).

What powers this

This calculator runs entirely in your browser. It needs no account, key or feed, and nothing you type leaves the page. The maths is the same commodity matched-betting and value arithmetic used across the industry, implemented carefully and unit-tested.
