Agree that the limit of 5 per level is ridiculous. And, to collect the rewards at 180 points you would have had to play 36 levels and collect all five drops each level. Ho hum boring. Don't the developers ever play their own game? How was this determined to be a good idea?
I also have it back. However, now it looks like refreshing the board to get a good start doesn’t change a thing. That is, each refresh results in the same board. Unless you remove or add a booster each time.
