Each level within the ''Portal'' series consists of '''surfaces'''. Typically, a [[Portals|portal]] can be placed upon any light-colored flat surface, whereas an uneven or dark surface cannot be used in this way. In this way, the placement and location of portal-conductive surfaces is a fundamental design choice, and determines the way in which the puzzle(s) need to be solved. | Each level within the ''Portal'' series consists of '''surfaces'''.

In some Test Chambers, surfaces are blocked by doors or other obstacles, or must be [[Button|activated]] before a portal can be placed upon them. In ''[[Portal 2]]'', the only way to overcome some puzzles that lack portal-conductive surfaces is through the use of [[Gels]]. | In some [[Test Chambers|Test Chamber]], surfaces are blocked by doors or other obstacles, or must be [[Button|activated]] before a portal can be placed upon them.
