WGTyphoon: I would also recommend entering into the Free to Play tournaments that WGT hosts. This is a good way to test and hone your skills while earning some credits for wins.
This is partially true but it must be noted that this will not really earn the OP credits. To win a tournament at his level carries a top prize of 54 credits!
Bear in mind these tournaments are usually won by "new players" with extraordinary talents the OP will be lucky to earn .54 of a credit.
If I am lucky I can earn a maximum of 10-12 credits a day via the videos excluding the maximum of 7 views on the carousel. Normally I can earn 3 credits per day via videos.
Takes a while to earn enough to earn a cheap sleeve of balls let alone clubs.
