Hustle Castle lets you build your own castle in a similar way to building a vault in Fallout Shelter. You also collect people for your castle and assign them jobs whether it be in the kitchen or as soldiers to fight for you. You can even toss two adults in a bedroom to get a baby if you want.
The game starts off pretty standard, but it won’t take long to realize you will be tossing a lot of time into it waiting for things to build or tossing a lot of money into it to hurry things along. The game isn’t exactly paid to win, you can play it and proceed without real money, but you are at a distinct disadvantage by doing so. It is a fun little time sink if you just want to mess with something, but expect to be waiting for a lot of things. Best wishes and may the gaming gods bring you glory.
