## What is Circuitry?

Circuitry is a hands-on logic game that makes Boolean algebra, logic gates, and digital circuits easier to understand.

Build circuits by connecting AND, OR, XOR, NOT, and other gates, then experiment with different inputs to see how signals travel through your design.

Work through 21 progressively challenging problems to unlock new components. Then use Playground Mode to create and test circuits of your own.

Features:

- 21 logic-circuit problems
- Interactive circuit building and simulation
- 36 different circuit components
- Playground Mode for creating your own circuits

## Key features

- Interactive logic circuit diagrams
- Boolean algebra learning
- Logic gate puzzles
- Sandbox circuit building
- Unlockable circuit components
- 21 logic problems

### 5/5 — The best

*2026-07-17*

I can do whatever I want for free and there’s levels that teach you in a fun way

### 4/5 — Really good overall

*2026-04-20*

Very good but I wish it could help me and explain more so Im not stuck on one thing for like an hour

### 4/5 — great logic game

*2026-01-23, version 1.1.0*

nice game to learn about logic gates and its free, whats not to like about it.

### 5/5 — Exactly what I was looking for.

*2025-11-05*

I was looking for a logic simulator like logism evo, but for my IPad, and this fits that exactly!

### 4/5 — Good to learn but not fun to use

*2024-09-18*

It’s annoying connecting wires to each section. That’s it

### 5/5 — Excellent

*2024-09-07*

This is a fabulous “game” but the playground is incredibly fun and helpful. The only TINY LITTLE gripe is that it can be a bit challenging to move components with your finger and not select a connector instead - but this is not a big issue - using the pencil helps a bit. Did I say this is FABULOUS?

### 4/5 — I like it

*2024-08-10, version 1.1.0*

Why on earth does the 4-bit register have too many outputs!?!?!? That is very weird. Why that? Also if anyone’s wondering how to adjust clock speed use toggle latches. And the rest you have to figure out on your own if you want to slow it down even further. (yeah ik how but im quizzing u cuz why not) Also please make it possible to put text on the buttons and LEDs.

### 5/5 — Impossible a two xor gates

*2024-04-29, version 1.1.0*

S

### 5/5 — Amazing tool!

*2023-09-29*

There is actually a remove feature for components and if you take the later connection of each wire and touch and swipe it off of the component it gets rid of it too so not sure why it’s a problem with everyone else. I brought this to a fellow instructor in the avionics dept at the college where I teach, he has now downloaded the app and uses it in class. this thing even visually checks it against the truth table.  Good job guys I wish there were more levels and some info on the internet to figure out the one I’m stuck on. One of three… been on it for a week now

### 5/5 — Amazing App, Please Continuing Update

*2023-08-17, version 1.1.0*

A great app for learning different logic gate, It’s sad that it only has 21 problems.
Thank You for such a Amazing App for absolutely Free.
PS, 4 bit register has the wrong visual, hopefully it gets fixed. And I wish the clock can adjust the clock speed.
