The 2 rounders at Stars is probably very hard in comparison to say a Ultimate bet freeroll. I used to place in them a few times a week when they were running the bonus$ frees late at night a few years back, not that I actually ever unlocked the bonus money I have on the site, ever deposited, or even play there anymore. I think they do actually offer
real money Frees these days. I've cashed in Tilt's more than a few times about a year ago, but I couldn't tell you if they're decent these days.
