To unlock the Episode IV door (initially marked with a "?"), the player must obtain "True Jedi Status" on all levels. In order to obtain True Jedi, the stud bar that appears at the top of the screen for every level must be filled up; it flashes and the lights move around when this is achieved. The blue studs are worth 1,000 studs, the gold studs are worth 100, and the silver studs are worth 10.When you obtain true Jedi, you get one of the 17 pieces to unlock the door.
