Why are some timers green and others blue?
I don’t know either
I am 100% sure its made to confuse you to click on it. Usually a free speed up is green so the game changes the color so you think its free to rob your precious dino bucks
It is either 1: a visual glitch or 2: like what @Fancy-Spot said
I think its a bug sometimes happens to me
It’s a visual glitch, although I really think they know about this and haven’t fixed it because some players can get confused and spend their bucks.
