Palmbux - some people still claims that they can't cash-out their earnings but, I think the good news for Palmbux is they launched their V3 yet some complaints that it's just slowing things down and, as I experienced it also has some bugs.

Hybux - Their site is still down for reasons that paypal is limiting their acount since December 4, 2009. There's no update yet by their admin, and I think many people are saying that it'll be scam but, I hope not.

Upbux - They limited their Hi and low game but betting the minimum of .01 and the maximum of .1. Now its hard to make a $2 again :P.
