Popis: We investigate a simple game paradigm for intuitionistic logic, inspired by Wajsberg's implicit inhabitation algorithm and Beth tableaux. The principal idea is that one player, źros, is trying to construct a proof in normal form (positions in the game represent his progress in proof construction) while his opponent, źphrodite, attempts to build a counter-model (positions or plays can be seen as states in a Kripke model). The determinacy of the game (a proof-construction and a model-construction game in one) implies therefore both completeness and semantic cut-elimination.
