I bowl in a league that gives open play credits for split conversions, clean games, and certain scores like 33 in the 3rd 66 in the 6th, and 99 in the 9th.  Last night I was clean going in to the 10th.  I struck my first ball, left a 4-6 on my second ball, which I did not convert.  Did I have a clean game?

If you strike or spare on your first ball of the tenth, then it's a clean game the fill ball doesn't count.

But in some contests it my depend on if they have their own definition, s ,o you have to check with them.

But using the classic definition, then yes you had a clean game.

 Desk man said, "There are 10 frames per game, and you had ten marks".  I was just interested in seeing if anyone disagrees. 

Anyone know whether USBC has any special definition on payout for clean series or clean series in BJ.  I had 40 clean in BJ a few years back for about $500, but the situation never came up, and I never asked.

Our league changed the clean game rule this year to disallow the scenario you described. If you strike on the first ball, you must mark on the second. If you spare on the first ball, you must strike on the second. The purpose was to add a little more challenge to being "clean". There was some typical moaning at first, but it ended up being well accepted.

How can it be a clean game with an obvious open?

XXX = Not Open
XX# = Not open
X/ = Not open
/X = Not open
X- = Open
/- = Open
- = Open

How could it be anything else?

Rule 2 – The Game
2a. Definition
A game of American tenpins consists of ten (10) frames. A player delivers two balls in each of the first nine frames unless a strike is scored. In the 10th frame, a player delivers three balls if a strike or spare is scored. Every frame must be completed by each player bowling in regular order.

If you keep it simple and have a rule that states there must be a strike or a spare in each of the 12 frames actually thrown, then your #2 scenario is an open. That was my preference in our league meeting but I was voted down. Whimps. 

But you didn't have a chance to "convert" the spare on that last shot. So it would still be clean. Just my opinion of it though.

Your point is valid. That's the reason why after much debate, the league voted to not require a strike on that 12th shot. I got it and didn't push the issue further.
 
Still from a purist standpoint and for additional challenge, I like a definition that requires each of the 12 frames thrown to show a strike or a spare. Just my opinion though.
