Gold Balloons--any rhyme or reason to them?

Been wondering about those gold balloons, and how often their chests are unlocked.  Is it totally random, or every 5th one or something?

I feel stooopid to state I didn't realize for quite a while that you can open the ones on other towns--I assume they appear to me/other players, and not the mayor. (Hope I haven't been stealing chests...that'd be awful.)

Thanks, all!

We all have 5 gold balloons we can open every day @Buckeyes

One a day is for free and the other 4 will cost 3 tcash each to open if you choose to. And lol, opening them in other towns is not taking them for another player. They are meant for you, but I confess I had the same worry myself until I learnt how they worked 

Oh, thank you thank you--makes me feel MUCH better!
