Monopoly. Can't understand the current rules. Instead have the playfield Monopoly board with lights that move around from space to space. Maybe based on how many times a spinner spins when you shoot ball. Put in a target(s) of some kind to purchase a property. After you own all of the same properties, hit drop targets or ramps multiple times to add houses and ultimately hotel. Penalize other players who land on "your" properties based on your rent with or without additions. Maybe subtract extra balls also. Design it to play a lot more like the board game itself.
