We study Snipperclips, a computer puzzle game whose objective is to
create a target shape with two tools. The tools start as constant-complexity
shapes, and each tool can snip (i.e., subtract its current shape from) the
other tool. We study the computational problem of, given a target shape
represented by a polygonal domain of n vertices, is it possible to
create it as one of the tools' shape via a sequence of snip operations? If so,
how many snip operations are required? We show that a polynomial number of
snips suffice for two different variants of the problem.
