when will new levels be added

Zelda-6

I am now on the last level - 325 - when will new levels be added? Have I outplayed the developers....haha?

I haven't spent any real cash, even have 3445 Farm coins in the kitty. 

Awesome game of strategy & random effects combined. Love it.

Every couple of weeks generally, but King generally never give out a date as once they've got an update to put out, it comes down to individual stores when they choose to release it.
