Boobs in the City / Cum & Gun: Tips for Green Gem Accumulation

Hopefully this helps out Tasha, it's mostly just be vigilant about always completing daily quests, doing the best you can in Gang Bang mode, and building girls up for achievements- combined with ONLY using gems to unlock girls/fangirls and never wasting them on small things like fast opening a reward pack or resources that can be farmed. It's a very slow process, but it works..

While I know many people can't spend money, just putting in a little can benefit greatly from the rainbow gems via the Battle Pass, daily VIP passes, and Shiny level. All can temporarily raise the number of green gems obtained for the duration of a month.
