In order to identify and define the model of language games it was analyzed several best-known and most important works of writer,from novels, collections of poetry, picture books to the dramatic parts. Literary theoretical and stylistic analysis determined the incidence model playfulness in all literary forms. The most extensive analyzes is the novel Shoeless general, which Hranjec described as one of the best contemporary Croatian children's novel.
