 As mentioned above, in the standard dialogical framework, there are two kinds of rules called the particle rules and the structural rules, which will now be introduced. The rules of the game determine which sequences of moves are plays—i.e., which sequences are legal. Hence the name “play level” for the level governed by these rules. First, the particle rules will be presented and an example will be provided. Then, the structural rules will be presented and three examples will be commented.
