Response from developer

Thanks for playing, and for the feedback. With the latest 2.0 update there’s now a hints button for whenever you’re stuck. Happy building!

great logic game

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

Exactly what I was looking for.

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

Good to learn but not fun to use

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