Dexter's Diner, where you select your stage/missions is a veritable loot heaven. Your characters never lose money if they die at Dexter's Diner, so each time you complete a stage, walk around the place with any Jedi character and force pull studs from all the objects around the hub level.
In stage 3-6, have a second player take control of the boss and force the character to jump over the lava pit. Just before Anakin Skywalker hits the lava, have the second player hit pause and drop out of the game, resulting in the AI taking a hit. Keep repeating the process and you can force an easy win. Pun intended.
Defeating Droidekas
Double jump them with X while in the air to take down its shield.
Disco dancing Kaminoans
Explore every room in the level "Discovery on Kamino." You will come upon a somewhat dark room with two or three Kaminoans in it, a blue stud behind a forcefield, a square on the floor made of several round spots, and what appear to be speakers on the wall. 1) Use the Force to transform the speakers into what look like record players. 2) Walk onto one of the round spots on the floor, and wait for the other character to move onto another spot (or have the second player move the other character onto it if you're not playing alone). Then you are together standing on two different spots, other spots will light up. 3) Each time more spots light up, walk onto one of the remaining pale spots, allowing time for your partner character to do the same. Eventualy, all of the spots will be lit. When all of the spots are lit, disco lights will begin to flash, a funky rendition of the Star Wars theme will play, and the Kaminoans will begin to get down!
Disco-Dancing Chairs
When you're in Dexter'sDiner go through the door with green lights & a 1 on top. Then go to another door with green lights and a 1 on top.You will be in EpisodeI:The Phantom Menace-ChapterI:Negotiations. Now when you're in a room with lots of chairs and a table over them, destroy the two boxes to the left of the door also go back to the chairs and the table and hold down circle when there's a green or blue glow. Now the chairs will put out away from under the table and dance around & there will be music on. And that's how to make the chairs dance.
Fights
When you're at the place where you select your levels, go outside into the parking lot. Out there, you'll see a lot of people there. Be a jedi and look for a dark jedi and swish your lightsabor at him. Then the fight bgegins! You can also do vice versa: Be a dark jedi and look for a good one.
Infinite Studs
At the very beginning of the level "Darth Vader" you must run through a corridor crumbling into the lava. Its possible to pick up around 3000 studs before the end, however if you fall into the lava before going through the door , youll be taken back to the start, not lose any studs and all the studs you already picked up will regenerate. Its possible to make around 18,000 studs a minute by repeating this.
Keep health high
In whatever episode and chapter you are playing, copy the type of your current opponent. For example, if there are hordes of disguised clones ready to shoot you, switch to disguised clone and they will not attack, giving you time to shoot them. They will probably follow you, especially if you are a battle droid. Note: Note this does not work on Bosses, Sith, General Grevious.
Switch Hitting
Freeplay (or Free Mode) is best for exploring previously cleared stages for studs and minikit parts. A preset "cast" is selected for a particular stage or mission which allows a player to access all the doors previously missed in Story Mode. Use the L or R keys to cycle through the cast while playing on free mode.
