Once Upon a Galaxy Random Deck Simulator – Version 1
I just finished building something I’ve never really tried before: a full-on web app that randomly pulls and reveals card art with some slick animation.
This is Version 1, and it started pretty simple. The goal was just to pull 12 random items from a Google Sheet. But as I kept going, it got more fun. I added card images, color formatting, and eventually turned it into a clean little draft-style experience with animated card flips. Each card starts face down and flips over one at a time.
I used Google Apps Script to pull data from the spreadsheet, and then built everything else using HTML, CSS, and JavaScript. I learned how to make cards flip using CSS transforms, trigger animations with delays, and build a layout that actually feels like a digital booster pack.
This was my first time coding something like this, so it was fun to see it evolve. I just kept building on each piece as I figured it out.
Anyway, if you want to see it in action, head over to https://motumbo.net/galaxy.
More updates coming soon!
