Well, tippgames didn't work out (not open to US players), so I'm moving on to try gotya.com. This thread will document that journey.
Deposited $5, got a $2.50 bonus, plus the original $5 they give you is still in there, so I get to play $12.50 for just $5, which was a nice touch. You have to make $30 in winnings to withdraw, and as I always do on a new site, I'll make a minimum withdrawal as soon as possible to test their responsiveness.
Game #1: Bejewel Action. Played 3 games and already have maxed out my ranking (2000) and have no regular duels open to me anymore. In fairness, I got super high back-to-back scores with some serious luck involved. But now that game may be pretty much dead for me after just 3 tries! Won $1.20 or so, then won $3.70 or so, then I think I actually lost the third game despite a 2M+ score. (You can't see your opponents scores until the tourney is over, but it shows me in 2nd place, which shocked me.) Can't wait to see what the 1st place person got and whether or not my rank goes down when I lose that tourney.
More to come!
