The Ad Multiplier is available on Mobile, and is offered as an optional opt-in x2 multiplier, in exchange for watching an ad. You scratch our back, we'll scratch yours!
Each Capitalist is allowed to view 5 ads per day, per planet. Once they view the ad, they can enjoy an additional x2 multiplier boost to their profits for 4 hours.
Please note that the x2 multiplier adds on an additional x2 to your current amount, and does not double what you currently have. For example:
3 purchases of x3 multiplier + x2 Ad Multiplier = x11 multiplier Overall; x3+x3+x3+x2=x11
