I mostly play on my phone during the commute, so if a site isn't fully optimized for mobile, I don't even bother. A lot of these modern casinos are just desktop sites squashed onto a small screen, and the buttons are impossible to hit. I was checking out the interface for the new Wonderluck casino Australia launch, and it looks like they actually built it mobile-first. There is a breakdown of their platform features at https://wonderluck.info/ which mentions the tech stack they are using. It’s refreshing to see a clean UI without all the laggy animations that drain your battery. Hopefully, the app stability holds up during peak traffic hours.
