Hi again,
I don’t want to let this thread die-off. Too much valuable info is possible to be derived.
To perhaps get the ball rolling; I’ve got a whale at Lucky Nugget casino that has been playing for about 6 months now. I’ve been very surprised (pleasantly) that LN has done such a good job of retention.
Also have a whale at Spin Palace. They too have done a fair job of retention and the player has been there about 9 months; though play has been sporadic in the last 3 months or so.
AllSlots casino has done a fair job of retention with one whale and they’ve been playing there about 4 months now.
