This article provides a brief overview of the main results in the field of contractible digital spaces and contractible transformations of digital spaces and contains new results. We introduce new types of contractible digital spaces such as the cone and the double cone. Based on this, we introduce new contractible transformations that covert the digital space into a homotopy equivalent to the first one. We group together these transformations and get 6 types of contractible transformations. These transformations can be used to convert a closed digital n-dimensional manifold into another closed n-dimensional manifold homeomorphic to the first one.
