Are opponents autopets-style opponents (e.g. recorded and replayed so you don’t have to wait?)

I’m confused about a lot of things about the game; I guess most particularly the letter draws — do I and my opponents get the exact same sequence of letters when traded in? Do we draw from the same (replaceable? Non-replaceable?) bag?

When I went to sudden death I saw very different words — in my case, I drew a J — was that it, since my foe only used a word with a G, I was basically guaranteed a win. Was that poor word choice on his part, poor or no trading, or a different tile set the foe had?

I think it would be nice to see all the possible letters in the ‘bag’ when we’re looking at trading.

Finally, is there a time component? It would be nice to get some indications about the opponent - maybe showing where they are hovering / clicking, or a clock countdown.

Also - fun!
