Someone posted this in one of the RR3 Facebook groups recently, and BY GOLLY IT WORKS!  In 2.0.2, anyway.  I just picked up 200GC.  It exploits the "welcome back!" bonus.

About to try it again, see if this is repeatable.

I'm posting the exact text from the FB post, except I've removed the attribution to the person who originally posted it, as I don't know if they want to be named here.

EDIT - I suggest iOS users read THIS post, which gives the step by steps "translated" for IOS:

In step 1, "close all processes" means quit from RR3, so just use the main Android back button and quit the game.

In Step 2, make sure you hit the Home button before the Monkey appears.

When he says "date is on auto", that means in your Android date & time settings.

When he says "press the game button", he means the main RR3 application icon n your app drawer.
