Continuing runs, 3, 4, 9, 2, didn't work
Next run, 1, 5, 9, 7, didn't work
Next run, 3, 6, 9, 6, didn't work.
I'm done with runs for tonight lol, still no idea what the code could be, since every run is random apart from the balloon. I also make sure to cycle through every balloon number just in case, but it always blows up on 10 pumps, so I assume it's 9.
