Demo watch: waiting on the public promo build
The 10,000 page will host the official Booming iframe the day the promo URL is public.
Until then, the fastest way to learn the cascade language is the live demos for Holly Jolly Bonanza and Holly Jolly Bonanza 2. Rules for Boost+ and the Christmas Tree are already documented on the 10,000 game page.
When the embed goes live we will flip this note to Live and bump the sitemap so crawlers re-check the game URL.
