Fake exit
A fake exit is any of three tiles which look slightly like an exit, but are not real exits; instead, all three of them function as walls. One is a Chip character in an exit, similar to that seen when Chip completes Fireflies or Special; the other two are slightly darker shades of blue compared to the real exit, with some black mixed in. One has a light blue outer layer, similar to the real exit, and one has a dark blue outer layer which makes it easier to spot as fake.

Fake exit tiles are used for the endgame sequence, but do not appear in any Chip's Challenge 1 levels. Like Burned Chips, Drowned Chips, Swimming Chips, or not used tiles, fake exits are not compatible with the original Lynx.
In early versions of Tile World Lynx, fake exits were read as real exits, and could be entered like any other exit. However, this has since been changed, and they are now acting walls. Only the "Chip in exit" variant has its own graphic in Tile World Lynx; the other two are displayed as walls.
The tile was first seen in Planet of the Teeth from CCLP2 in a section to the northeast of the real exit, and were also seen in Mads' Rush II and Tricks.
Other Meanings
The term fake exit is also used to refer to exits with clone machines under them, such as the ones at the start of Quad-Boot. Such exits cannot be entered by Chip, but unlike the other fake exits, cannot be identified visually.
