Whats the easiest way to earn credits?
Buy them (with your credit-card or via PayPal). 100 credits cost 1 US dollar. It's unrealistic to expect to win any substantial amount of credits in tournaments.
The most accessible way to earn credits is level up your tier
... except that the original poster has been in the Pro tier for weeks now, and advancing to the Master level is anything but easy. (Especially if you're not cheating, i.e. if you're recording all of your rounds, good or bad.)
agreed this site is full of people that won't finish rounds... truly rubs me raw!!!
