Beware! This game is fun, addictive and a RIP OFF! Yes, you will have to spend your real money if you want to advance. You need to buy upgrades and hearts. The rewards earned are not enough to get you the supplies (energy, staff, skills, etc) that are needed. I confess I’ve spend more than I like to admit on this game. I have purchased staff several times. THREE times now after paying for staff I am ripped off. It will show me who I got and then they will not show up on my board. First time it was a doctor, second time a paramedic, and this last time was a nurse. Three strikes and your out!!!!! There is no way to contact support (that I can find) and even if I did, I’m sure they would just blow me off. I will NEVER give them another cent!!!!!!!!!
