I didn't make this for Newgrounds, but since it's a Flash I might as well submit it. It's got rules if you've never played Keno before.
Also, don't complain about any patterns. I've double and triple-checked the random number generator with a statistics professor, and it's legit.
I realize that the rules of mine differ from other casino versions. Mine has a ten spot maximum, and the payouts are tweaked because I'm not a casino and virtual money means nothing to me. If you want real world payouts, visit a casino.
