I’ve been been exceeding 4 figures with party poker for over 2 years. My commissions are up about 50% since the launch of blackjack and side bets.
My poker rake is pretty constant, recently growing a 2% a month (if i send players), with my new players helping replace lapsing players. so, the “gambling”/non-rake portion is 85-90% of the gain.
I think in the long run, it may hurt, taking away average players who have lost their stake gambling.
BTW – i’ve received huge (high 4 figures) chargebacks in the 2-3 months before the addition of the casino games. So, maybe people’s negatives have something to do with the negatives?
