Each day we get 100 pots of gold BUT after working ones way up we need 500 to upgrade a supplier so we have to wait 5 days before we can proceed. That is not conducive to enjoying the game but is frustrating. I'm sure that when I finally reach the next stage it will be far more than 500. Another annoyance is that a prize is an upgrade of a building BUT when one does not have that building the upgrade is useless. I have loads of worthless upgrades.
