Interesting game.
I think there are still some kinks to work out.  Like right now green bucket shows 0.02, which fell about 4 blocks ago according to the history file.  The history file shows subsequent blocks to be no play because green bucket is 0 according to the file.
It showed 0.02 before the green fall (on screen) but paid out like 0.01 just like it represented in history file. (I had/have the red bucket paid in)
Seems like the screen refresh is behind but the history file is probably accurate.
Interesting that when you add to the bucket though the screen shows it almost instantly.  FYI I don't see any pending transactions for the green bucket to account for the 0.02 on screen.
Keep up the good times with bitcoin!
