We have a standard set of Ace rules that will apply to most of our events if our staff is the Tournament Director. Those rules are as follows. 

If no ace is hit in either round, we will have a throw off for any pool not hit. If an ace is hit during the throw off, you or your team wins the pot for your pool. If multiple aces are hit, those individuals or teams will split the ace pot equally. Otherwise the top 3 closest are paid. 

1st 50% of pot
2nd 30% of pot
3rd 20% of pot
