Cool game, but maybe give us some kind of reward like maybe seeing a circuit board with a flashing led and maybe a few more circuits to build.
Then you could have something here!

Love the Idea,(I actually wanted add something similar in my game) but I don't really understand it, what i assume are resistors looked identical but weren't interchangeable, also the parts and how they fit together isn't explained so I was kinda confused as I do not remember the circuit diagrams.

Nice, great entry!

This one has some juice.  Great entry.

Solid baseline for sure. Like others have said, more circuits and more explanation on them. *I* know how a 555 timer works for an LED because i've done it in real life, and some explanation on why you're placing those resistors, caps and the LED on the pins you are would go a long way. Love the concept though, I've always been a big fan of teaching circuit theory through games.

When I was a kid I had one of those Electronic Kits from Radio Shack, and I loved it!  This takes me back to those days! 🙂

I was having some trouble fitting the symbols into their spots.
I finally figured out it was because I was trying to line up the squares exactly.  When i do this, the mouse pointer is slightly off the target so the game thinks I am in the wrong spot.  (But visually it looks correct, so it's kind of confusing haha.)
