Superficially, Dominoes on Acid is a solitaire variant of Dominoes with weird colorful tiles (and this view is enough to play the game). But on a deeper level it is a GUI for natural deduction. Every completed domino is equivalent to a proof of a tautology in classical propositional logic. The game can be played online as an applet or offline as an application. It is built on a simple isometric engine that can be used independent of the game. GUI:Есть Терминал:Нет Windows альтернатива : Программные требования : JAVA JRE Аппаратные требования :
