You can only, as far as I could tell, one-table. I had about $225 total to play with after the bonus, and i did $2 bets until I hit $300. Then I switched to $3 bets. Continued there until I hit around 450ish, when I switched to $4. I never went above that, because the bonus cleared at $538ish but I was planning on moving to $5 if i hit $600.

I'm not sure if that was a smart way to do it, but it worked. I would have moved down along the same scale though, so it couldnt be too bad.

Did I run rediculously hot? Well, I guess, by definition of coming out ahead I guess I did. I played straight down the chart (although i misclicked and doubled down once when I was dealt K7... woops..) and it worked out for me.
