CerinoDevoti: You don't need to buy any credits at all. Check out the "Earn Free Credits" offers and surveys under "Get Credits" at the top of the page. I'm at Legend Tier with all the stuff and haven't opened up the wallet one time. GL
Cerino, I have seen you and others repeat this over the years. However this is based on your experience and geographical location. This is NOT the same for everyone.
In my case I get 7 carousel views per day - no extra views, so if I play every day of the year I can amass some 1916 credits annually.
I have had one survey in 4 years - 90 credits. so in 4 years I have gained or potentially gained 7664 credits.
Can you explain how I could have purchased and upgraded clubs let alone use balls other than starters balls?
The offers are for products I would not use or IMO are poor value anyway.
And for the record, the one survey I did qualify for took half an hour to complete - at the rate of $1.80 per hour you have to be kidding me.
Of course I would rather not pay out of my own pocket, but I have no choice and I suppose I am lucky enough to afford to, and see the game as good value for the entertainment it provides.
But just blindly saying you do not need to buy credits is not necessarily correct, well not if you want to play at a reasonable level with decent equipment.
