Which coin room are you playing in ? The lower tiered players play off their tees in the lower rooms. If you play Chelsea for example they gain quite a big tee advantage. If you play Rio , or even Casablanca you will go off the same tee. There are a lot of very good mobile players showing as master for example that only ever play coin rooms and therefore may not level up as you would expect. They are just good at what they do.
Also , I believe it has been said before the higher up the levels you go it becomes tougher to putt , and also the requirement to be ever so accurate on all shots become greater.
It’s not you , it’s just the way it is , try the higher coin rooms and you may be surprised!
