The game "SWITCH or NOT? - brain teasers and logic games" is designed to tell you about the logical elements (logic gates) and the principle of their work. All logic problems are constructed in such a way that gradually increasing the complexity, to introduce you the world of computer logic. The idea is switching on/off the gates to activate the last item. Logic elements are included if the logical condition is observed. What? All different and depends on the type of logical element. If the item is enabled, it produces an output signal which in turn is supplied to the input of the next gate, thus enabling or disabling it. The gates are single-or multiple inputs and single output. A logic element with one input is "NO". If the input has no signal, it turns on, but is only to give him the input signal, it immediately turns off. In the game there are elements with two inputs: "AND", "OR", "XOR". "AND" (square) is enabled if BOTH its input signals in all other cases it is disabled. "OR" (triangle) is enabled if AT LEAST ONE of its inputs has a signal. "XOR" (rhombus) is enabled if ONLY ONE input has a signal. Controlling the input signals by means of switches is your aim. All these elements are linked in one chain and for activating the last logic element you should toggle switches or not.
