You can avoid paying for coins by buying and sellingi tems in the farmers market.It is way better than watching videos. I have been spending coins freely and still have over 300,000 coins unused at any given time.
I have been getting challenged,every one of them is way above me in improvements.(used to be pretty even.)This seems to apply to the random challenges too.I have not won one since the update.
I have found the blue tickets harder to get than you would think.l have yet to use a gold ticket. Also,Would love to be able to sell the tickets for even half what they charge for them.
It freezes on me too.this usually works.Exit tte game for 4 to 6 mins.When you return.you should have the supplies that you would have had if the timer had never stopped.(the timer will usually start when you make a move
