Major items are all 14 Energy Tanks, all four Reserve Tanks, and all unique items. Minor changes to the game can be can be found on the randomizer information page.

Neither Speed Booster nor Screw Attack can be at either of the first two major item locations.Varia Suit also cannot be in Lower Norfair.Varia Suit cannot be in Crateria, or at Morphing Ball or Energy Tank (Blue Brinstar).Gravity Suit also cannot be at Plasma Beam, Spring Ball, or Space Jump.Gravity Suit cannot be in Crateria, and can only be at X-Ray Scope or Energy Tank (Waterway) in Brinstar.Morphing ball is always at one of the first two major item locations, Morphing Ball or Energy Tank (Blue Brinstar).There are a few restrictions on certain items. The goal of these changes is to balance out item distribution, minimize idle time in the game, and minimize the chance of a soft lock. There are several other minor changes made to the game. For example, if Varia Suit is after Draygon, Gravity Suit cannot be in a location that requires Varia, like Lower Norfair(in most settings). "Logic" or "skill settings" refer to the way that the randomizer sets restrictions on each item location to ensure that no progression item is placed behind an obstacle that requires it to continue.
