Not too much ads, but this is NOT an idle game. You cannot make any progress while offline. Nothing happens unless you are sitting there staring at the screen. The gameplay itself is not too boring, but alot of upgrades have agoat no effect and are just designed to be expensive to mature you spend resources to unlock the next area. Even if you pay, there is a period where you will hit a wall and have no choice but to sit and spend 30 hours staring at your phone to progress. Would not recommend.
