Progress has been made! But still running into some problems. Namely, I can't get only one random LED to blink. Anytime the serial monitor returns a 3 or 4 for randNum, I get two LEDs. I introduced a delay and confirmed that they're lighting up separately, I'm guessing because of the gameState, but I find it odd that it only does it when randNum is 3 or 4, and never for 2. I can't figure out for the life of me how to get the program to select a single LED, turn it on and keep it on without turning any others on. I tried commenting out the line in void showResults that also states digitalWrite(randNum, HIGH); but that didn't actually do the trick. Any help would be greatly appreciated!

I think the random() function on arduino should work well for this!
