User blog comment:Kirbycupcake64/Did you see the new update ROBLOX may be making?/@comment-6591198-20130704165923

My understanding is that it costs ROBUX, not actually money, to play games. If you get enough place visits, theoretically you could convert the profit from tix to robux and gain access to the game without actually taking any money out of your (or your parent's) wallet.
