Shapes are drawn optionally with a scale and contain three bugs (see page 7). In addtion, the commands can be mirrored (LT/RT → RT/LT) or reversed (1,2,3 → 3,2,1).

Bug Reference

All bugs are added to the program, not removed. When added, they are either added after another command or they split another command in half. Note that all bugs are added before the program is mirrored or reversed.

Splitting Bugs

Splitting bugs take a single instruction and split it into three, but only a few specific types of commands can be split:

Command Type	Resulting Command Sequence
Forward FD [R>1]	FD a, [Rotation Bug], FD b where a+b=R
Rotation (90°) LT/RT 90	LT/RT 180, [Arc Bug], RT/LT 90 or LT/RT 90, [Arc Bug], RT/LT 180
Rotation (180°) LT/RT 180	LT/RT 90, [Forward or Arc Bug], LT/RT 90
Arc (180°) LT/RT 180 R	LT/RT 90 R, [Forward or Rotation Bug], LT/RT 90 R

Addition Bugs

An addition bug occurs between two commands, however the possible bug type is influenced by the types of the two commands:

Former Command Type	Latter Command Type	Resulting Command Type
Forward FD R	Arc	Rotation
	Otherwise	Arc
Rotation LT/RT A	Arc	Forward
	Otherwise	Arc
Arc LT/RT A R	Arc	Forward or Rotation
	Rotation	Forward
	Otherwise	Rotation
