Test your knowledge of the principle of logic gates in Switch or NOT puzzler. The goal is to switch on/off the gates to get the electric current to the end. SWITCH or NOT? is educational and introduce you to world of computer logic often studied at the Introductory Computer Science classes in college. Starts out fairly simple but with more than 70 levels designed to develop your IQ, memory and intelligence it’ll get a lot harder soon enough. You have limit amount of moves indicted at the top of the screen, once it decrease to zero, you must try again. 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. If you like smart games and logic puzzles or you need brain teasers and memory development, if the words intelligence, memory and logic much meaning to you, then this game is for you.
