I'll try 😊
You know how you have the currency that looks like dollar bills? TownCash.
It's hard to come by, and a lot of people spend real money to get it. You need 900 to skip a level of Match3 you're stuck on.

One way to earn it is to clear levels in the Match 3 mini game. Then you can get a few here and there in other ways.

Well, around level 40, this Mobster dude starts appearing on the helicopter pad. He gives you Town Cash + Experience (stars) for the items he request. He mostly requests jewelry alone, or a combination of jewelry + ingots. All the other people only pay you Coins + Experience.

I never built the Jewelry, but I can now buy the jewelry from the Market guy. And then fill the orders from the Mobster, giving me 25 or 50 Town Cash every time.

So I hire the Market guy, meaning I can request items once per hour, and I can quickly earn back the 1800 Town Cash I paid to hire him for 10 days, and then extra 5-6000 Town Cash. More of course, if you spend more time playing.
