 The game rules (particle rules and structural rules) constitute what is called the play level of the dialogical approach—constituting the backbone of dialogical logic in the Lorenzen and Lorenz tradition—which should be distinguished from the strategy level, the dialogical counterpart to demonstration (see  Section 2.1.2).  The play level is constituted by individual plays developed according to the game rules, whereas the strategy level consists in a certain perspective on all the possible plays regarding the same initial thesis. Validity belongs to the strategy level, but the meaning of statements and determining what logic is currently being used both belong to the play level through the game rules. Most non-dialogical frameworks focus on the level dealing with validity, and some dialogical ones also, following in this regard Felscher.
