I kinda like this game, but I've been playing for a little while and I've now competed in 2 of the special events and both times I checked the game almost every hour and kept doing the task because I was trying to win those diesel locomotives and both times now, even though I did everything possible I came up just short on coins, like the game was trying to keep me from getting those few coins I needed. If you don't want to give those then you shouldn't put them on there.
