Don’t bother, unless you enjoy watching ads for no reason. – Idle Factory Tycoon: Business! Review

You need to watch a ton of ads in order to progress, but 25% of the time, the ads don’t work. You sit through the full 30+ seconds, wait for the end screen, and then the game does not register that you’ve completed the ad. Huge waste of time.
