Long live Black Potion!
Reviews for "Serial Numbers"
Played it. Shared it.
It gets into you, always wanting to improve, going further.
Would recommend 5/5
I played a couple times, but can't get above 12k. This game is really good, I don't think I've enjoyed a flash game this much since Learn to Fly.

Try to slide the number to another one ;)
It's the sliding technic that is not show enough ine the tutorial :s
fun time waster
Brilliant game. Lasted me for ages, but definitely something that should stay on a phone. Or Newgrounds.
