## SWITCH or NOT?

The game "SWITCH or NOT?" 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.

Features "SWITCH or NOT?":
- 72 logic problems designed to develop your IQ, memory and intelligence
- stylish and minimalistic design combined with intuitive controls
- addictive gameplay, where each brainstorming ends with a shout of Eureka!
- brilliantly-designed logic puzzle with multiple solutions
- ideal for people who love intelligence and IQ games

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.

This is a fun puzzle game based on digital logic. I personally found the vast majority of the puzzles to be easy (could solve them without resetting and in reasonable amount of time), but this is an excellent introduction to digital logic. The real game, for me, started with the introduction of latches and some amount of feedback. I can see future levels having shift registers, state machines, and other more complicated, but useful circuits as puzzles.

Played all the way through the regular 83 levels, had a good time; 'bad' levels (those that just required you to ignore the majority of the level to solve) went by quick enough and weren't common enough to be a bother.

The space invaders game mode wasn't quite my speed, though it does act as a bit of a time attack mode. The things I didn't particularly care for were that, for a time attack mode, the goal isn't clear from the start of the level; the location (except for the first wave), density, and enemy type aren't knowable until they show up on screen, which isn't always enough time for circuit changes to propagate through. This means that, except for the intro levels, I had to restart (what I felt was) too often just because enemies appeared unexpectedly and one slipped through. To be clear, the criticism is that some amount of prior knowledge is required.

Great game, I did all levels! :D
Works fine, no bugs and not very easy.

Easy peasy tiddie squeazy.

Very very fun and brain teasing! I liked it a lot!! I cannot wait for more levels.

I once had a job as a micro-controller programmer. It was the most fun job ever because it was like playing this game all the time only with even more logic elements.

The game is good, solid length of 83 levels with a promise of more. For me with experience PLC programming the first 72 levels were easy, but after that when the memory element appeared it got a bit more tricky.

The game is educational and with a very nice interface. Music is nice. The alien defense option is nice to give this some plot although I prefer to have it turned off. Two different color palettes is also nice, I prefer the black one.

Only things that prevent me giving maximum score is technicalities like, lack of fullscreen, lack of special animated cursor and lack of option to turn off sound within game.

Looking forward to next levels! Could they contain something new? One shot monvibrator, timing delays? Would the game be fun for general audience if you introduced analog inputs and elements controlling analog input values and the goal would be to produce final output with values in certain margins?
