I know about the "3 days in a row for a 1 tank coin" , but i have 15 days in a row and i just get 1 tank coin each. Can you please increase the cost of tank coins for each time you get three days in a row.
I had a problem:A prestige 7 was inviting lower lvls that did not prestige to his game. I don't know the user name,but i joined in and the game was full of lvls 1 - 10
A good way to be defended is put a lot of Tack Factories and then upgrade all of then to Tack Storm(which puts spikes all around the track(s))then you will have a good defence. trust me i tried it. hit the + if you tried and liked it!
