## What is SWITCH or NOT??

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.

### 5/5 — Супер

*2026-05-15*

Отличная игра! Разработчикам благодарность!

### 5/5 — 楽しいけどちょっとバグ

*2022-11-15, version 1.4.0*

level20。切り替えられるスイッチの数が2になってた。クリアには3必要。リスタートしたら3に戻ってた。ちょいちょいあるので多分広告見せるためにワザとやってる。手数足りないじゃん！となったら、落ち着いてリスタートしてみて。

### 5/5 — 良いゲーム

*2022-03-09, version 1.4.0*

パズルゲームとしてとても良いです
じっくり考えれます

### 5/5 — Fantastic, just one little thing

*2021-12-16, version 1.4.0*

Very nice, you made logic diagrams into a game. I like it! However, there’s no option to mute the game. Sure, the music is ambient and can’t be heard easily if music from another app is playing, but it would be nice to have the choice.

### 4/5 — 4

*2021-11-29*

Заделайте возможность убрать музыку. В целом игра хорошая.

### 4/5 — Half fantastic

*2021-02-11*

Great game, interesting puzzles. Personally don't like the levels where timing matters as much. The second mode doesn't seem to work,  the first level seems as if it doesn't allow for any actions and restarts level even when trying to watch ad to skip it

### 5/5 — Great game but not enough levels

*2020-08-19, version 1.4.0*

I finished it on the same night

### 4/5 — Galaga mode doesn’t work, or is misleading

*2020-07-16, version 1.4.0*

There’s only one switch to interact with in the first level of the Galaga mode, and pressing it at any time restarts the level. I’ve desperately tried finding other things to interact with, and nothing else seems to respond. Doing nothing also fails the level. Either I’m missing something, or it’s broken, and I’m not sure which.

As for the 94 levels of the game otherwise, I loved all of them from start to finish. It was a great way to spend an evening. I hope that more gets made for this game, because it’s a joy to experience.

I’d like an option to turn off the music, though. It’s a bit of an annoying loop.

### 5/5 — めちゃ楽しい

*2020-07-07, version 1.4.0*

工業系の学校に通っているのでこんな感じのアプリ大好きです

### 4/5 — Awesome Game - Ready for more levels

*2020-04-30, version 1.4.0*

The game is amazing if you are looking for a game to test your logic and deduction skills!  I do not believe I have found one that I enjoy more.  Definitely worth the cost of disabling the ads which at the time I did was only 99 cents.

I only gave it 4 stars because it appears that there are no more levels after 130 or so.  I cannot remember the final count.

Please make some more levels.  The music and the colors are also pleasing.  This game is very entertaining especially for the engineer folks.  Thanks for creating it.  I will be playing all the levels again!
