What do you look for when choosing an online casino?

I’ve been comparing a few online casinos lately, but I’m finding it surprisingly difficult to choose one that feels convenient rather than simply having a huge amount of advertising around it. I usually like having several game categories available because my preferences change depending on my mood. One day I might play a few slots, while another day I’d rather look through fishing games or live casino tables. I also tend to use my phone, so I want a site that is reasonably easy to browse without constantly zooming in and out. Another thing I’ve learned is not to judge a casino only by its welcome offers. I’d rather understand how the games are organised, what payment options are available and whether the important terms are easy to find. Has anyone recently found an online casino that they thought was particularly convenient to explore?
