There are several ways to get studs by destroying chairs, trash cans, etc. There are two fan covers on the ground outside the cantina that give lots of studs. Inside the cantina there is a location that gives a lot of studs. In "Episode VI: Return Of The Jedi" there is a table in the middle of the room with blue chairs. Use The Force on these chairs several times. Some studs should appear each time this is done.

Use the following trick to get over 50,000 studs easily. Go to the Podrace and use one of the speeders from the beginning of Episode II. These are great for hitting the pink crystals because they have better mobility. Use Subulba's Podracer when hitting the little poles. It is easier to hit them with a wide Podracer. You can easily get over 50,000 studs each time and it is one of the quickest levels.

Go to Chapter I of Episode III. Use a Clone Arcfighter and shoot everything to get at least 100,000 studs each time the level is completed.

Go to "A New Hope", Episode IV Chapter 5. Get to the part where you must build the giant door and break it. Make sure you have the "Character Studs" and "Stud Magnet" extras enabled. Keep killing the Stormtroopers until you think you have enough studs then complete the level. You should also enable "Invincibility" so you cannot lose studs or die.

Go to Mos Eisley Spaceport. Get in the Landspeeder. Go through the door with the Landspeeder. Use Ben Kenobi to jump over the nearby building. Build the bomb next to the wall of LEGO pieces. Hit it three times to make it explode or use a Thermal Detonater. Get into the Landspeeder and park it on the grey object. Pull the handles. After getting a car wash, give the Landspeeder to the Jawa behind the wall. He will give you the money.
