{{ImageBox|position=none|name=''Non possum vivi''|screenshot=Non_possum_vivi_13_4.png|width=200|screenshotDesc=''Non possum vivi'' in level 13 section 4. Note that a paper ball is required to complete this section, but the ball is a stone ball, and there is no way to change it to a paper ball in this section.}}'''''Non possum vivi'''''<ref>speedystoneball's term; short form: ''vivi''</ref> (Latin for "(I) can't live"), also known as a '''wrong ball''' or '''stalemate'''<ref>Dilant's term</ref> is a softlock where the player is unable to make progress due to having the wrong ball material with no access to a [[transformer]]. ''Non possum vivi'' can only be resolved by restarting the level; not even a [[suicider]] can solve the problem, since dying does not transform the ball. ''Non possum vivi'' is usually a serious flaw in the design of [[mapping]] (worse than ''Non possum mori'' ), but can generally be easily avoided by the map maker's careful inspection of the map logic. ''Non possum vivi'' appears in both [[original level]]s and [[custom level]]s. In a broader sense, ''non possum vivi'' can refer to any softlock that cannot be resolved with a suicider.
