I am working on a circuit that requires 3 leds to light up. I want to have it so each time a high (or low it doesn't matter either way) signal is received another light comes on until all three are lit up and then the setup can be reset to do it again.

Let me clarify a bit, the leds are to represent the number of times a number was guessed incorrectly for a game I am making. Each time a choice was guessed incorrectly I wanted another led to light up to signal that the guess was wrong. the leds would keep lighting up every time someone guessed incorrectly until all three were lite. I don't know how to make the circuit that would add the incorrect guesses every time a high input was received.

Off the top of my head... probably a decade counter xD
Everytime it gets a pulse, it will 'count' up. You may need additional pieces, but this will serve as a good starting point. (Note, they can be chained together if you need LOTS of LEDs)

I had 3 decade counters and unfortunately two are now in use and the other disappeared. Is there a way I can recreate a counter with gates.

There sure is.
What kind of gates and quantities do you have on hand?

haha. That sounds like an interesting project, but I cant work it out for you right now.
Counters are incredibly easy to make with JK flipflops...
