Possible
Possible is the 81st level in Chip's Challenge Level Pack 3. It was created by David Stolp, who intended this level as part one of a two-part series that also included the truly impossible impossible, made so by making Possible completely symmetrical. His impossible level is based on an impossible pencil-and-paper puzzle, in which you must draw a line that only moves vertically and horizontally through a 3x3 grid of nine junctions, and must pass through each square exactly twice. The ability to pass through one of the square three times, thanks to an extra recessed wall, renders this puzzle actually solvable.
Move DRD 2R into junction 5, at the center, then turn right and further east to number 6, where the extra passage can be seen; after Chip passes over this recessed wall, he can step sideways off the force floor leading to it - a method that works in both rulesets. Pass through junction 3 (the first junction in a pair can be taken in either order), turn east at junction 2, and cycle back through again; repeat this sequence for junctions 1 and 4, then 7 and 8, and finally between 9 and 6. With one chip remaining, pass through the extra entrance out of junction 6 and then take the last chip from room 5, with an exit nearby.
