I've been playing for years on Windows 10. I'm currently on the road so I tried my Chromebook. Unfortunately it looks like its not powerful enough to run the full game. In "Stroke Mode, Multi-Player" I only get an option for 9 holes, no 18 hole option. I am able to play a full 18 holes in "Stroke Play - Solo Mode".
I think Professor . That was a sign . A sign to direct you to a new curriculum . You see Professor . That the WGT Gods have proclaimed that for your playing benefit and time management concerns .
They have determined that when one plays 1, 9 hole ranked stroke play round .
They will double that score every time to that of an 18 hole score .
IE : 18 = 72
9 = 72
This has the effect of cutting your online time in half at the same time as cutting your tiering up time in half .
Instead of 15 years to tier up . It only takes 7.5 .
Also helping on those long road trips .
Praise Paradise .
