*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. **Length**:- The paper is 6 pages.
