I joined a Canasta group, too, and we used to play at this cozy hotel bar. Great vibes! Anyway, I was checking out different sites and came across CardzMania, which was awesome for practicing against bots whenever I had a few spare minutes.
But one day, I messed around with some settings, and it totally broke my access to the game. It turned out I had to clear cookies for that site, just like you mentioned. Once I did that, everything worked again.
And while you guys are figuring out the glitch, I found a bunch of other
free online games that are super fun and casual, perfect for passing the time without needing anyone else to join in.
