Circuitry is a logic game that helps you understand boolean algebra, logic gates and digital circuits.

Circuitry provides an interactive environment to enable direct interaction with logic circuit diagrams. Construct solutions to complicated logic gate problems by linking AND gates, OR gates, XOR gates, and much more.

Progressing through the levels will unlock various logical elements and contraptions which you can use to develop circuits in Playground Mode. This is where things can get interesting!


- 21 problems
- Playground / Sandbox mode where you can build whatever circuits you want using the simulator.
- 28 different circuit components.

Really, really helpful.

Love this. Great app and an elegant way to play around and practice. This has been my doorway into understanding logic gates. I can’t think of a better, simpler way to do it.

I see suggestions of more complex components in other reviews from people smarter than I (ie the first review that comes up). A very, very simple thing in playgrounds would be a label component - just a sign that would let me label a given circuit so I can remember it.

I understand that the creator is just offering this up for free, which is 🤯. But I would be glad to pay money for a tool like this. The irony is that some people are probably undervaluing it because it’s free. Why not add in a few more of these advanced components that people are asking for and then monetize it? You’ve put work into this and it’s awesome. You deserve a little return on your time and brain cells!

Pretty good but needs more logic components

I really like it, it’s pretty user friendly and allows for the construction of some advanced stuff, but there’s a few more things it good use
1. Multiplexers/demultiplexers: many circuits use these and they and quite useful
2. Imply gates
3. Only gates: an only gate is an and gate with one input inverted, basically the opposite of an imply gate
4. Shift register
5. 2-Bit and 4-bit decoders
6. Binary division circuits
7. The ability to name buttons and outputs
8. Signs: an item that simply contains a title, used to label one circuit from another
9.the ability to adjust the speed of the clock, and a more defined off and on rather than that weird rapid strobing with the occasional off and on
10. ALU: this would be useful for many reasons, like many advanced circuits
11. The ability to increase the amount of inputs for certain gates, such as the AND/NAND and OR/NOR

Suggestions: these are just suggestion of what might be interesting to add but isn’t need
1. Binary reversible logic gates: those would interesting to play with
2. Circuit switching elements
3. Relays

Really useful and has potential

The app is very good at teaching you the basics of logic with the first few levels

I suggest that the difficulty of the levels do not rise as dramatically as it does

Other than that it is a great app and the playground mode is great for when you have any good ideas.
