-After every level, do not continue. Instead, leave the diner and break all "trash cans" by the doors outside. You can get a good few thousand if you are lucky.
-In the Discovery On Kamino level, if you encounter the broom where you had R4 to open the gate, use the Force on it. Money will come out. If you follow it around the whole room, money will still appear. This is useful when attempting to get perfect studs.
-When facing General Grievous in free play mode, go as far right on the cliff as possible. Go on the bridge then into the dome on the right. Destroy all the bombs and use the Force on the levers to get a minikit.
-Activate the "Invincibility" code so you do not die and lose your studs. Replay a chapter as many times desired and try to find studs.
-Head to Dexter's Diner and the places where you can enter the levels. Use The Force on the salt and pepper shakers to get about 1,000 studs each time.
-After any level, go to Dexter's Diner instead of continuing the levels. There are three tables in Dexter's Diner, but only two have salt and pepper shakers on them. In each one there is around 800 studs. You cannot destroy them with a lightsaber or by shooting them. You must use The Force to destroy them. After destroying them, you can also go in Episode I, Episode II, and Episode III to get them. There are two salt and pepper shakers in Episode I and II, and four in Episode III.
-Activate the "Invincibility" code, then play the Darth Vader level in Episode III. At the very start at the lava that you must jump over, go to the third hole and wait. A number of studs will pop out, including two blue ones. You may need to jump into the lava, but you will not lose any studs because of the invincibility. Die if you have not already (same case) then repeat as many times as desired.
-Use the Force on the salt and pepper shakers. They are on the tables at the diner. To make better use of this, do not choose "Continue Story" after you play an episode. Instead, go to the diner and get the studs from these shakers.
-Go to Episode I, then select the level with Darth Maul. When Darth Maul is running over the platforms/bridges, go to the very top. There should be a lot of studs up there, along with some Battle Droids. After they are defeated, get all the studs. Note: Do not use The Force on the elevator at the end.
