first impressions of WinBritish Casino were quite good, fair terms and conditions make it seem trustworthy. over time, though, I noticed the mobile site is poorly optimized, which is a big letdown. depositing with UPI was straightforward, but playing Yggdrasil games on mobile was a pain. the site started to feel clunky and slow, especially on my phone. initially, I thought this would be my go-to casino, but the mobile experience dragged it down. overall, if you’re playing on a desktop, it’s fine. but mobile users, beware. I’d look for alternatives if you plan to play on the go.
