A companion plugin for powering WPBingo.com
Install and activate this plugin on any web-accessible WordPress site. Create bingo squares to your heart's delight (I recommend creating at least 48 different squares for better variety)! A word of caution: the endpoint for the bingo cards supports the random orderby query param and could therefore become a point of weakness during a DDoS attack. In a serious production environment you may wish to disable this filter and instead fetch more squares (e.g. 48 instead of 24) then shuffle and trim them on the front-end via JavaScript. WPBingo.com is currently using this safer method.
You can see and swipe the front-end code that leverages this API data at WPBingo.com. The most important thing to change for running your own setup is the API URL.
Slides about this wild contraption are available from my WordCamp Miami 2018 presentation:
