How do you beat the Lego batman mini game ''Wayne Manor''?

Answer 1

First you destroy all the gray bricks, then get the tractor or lawn mower and run over everything, revealing a purple stud in the garage. Build the computer with robin's tec. suite and hop in the chair. Wait.... then you will appear in some kind of Mario land. destroy all the bricks by shooting them or ramming your head into them. After the few obstacles that you complete, there will be a black sphere that you jump into. You will appear at the top of Wayne manor, yet another computer that you sit in. Wait.... then you will appear in a very large room with rolling bombs around you. Roll the bombs into all 50 propellers on the ground revealing more studs. You should have 1,000,000 studs by now. Pull the switch near the area where you came in and yet again you will be at the top of the manor. You should have won by now.
