I agree, maybe for a small tourney, set aside small portion of the prize pool (or have extra fee for) a high hand of the tournament prize, like Ultimate Bet has (in ring games). Annouce the current high hand and update it as better hands emerge. Could be fun in a freindly game.
If someone gets a royal early it will probably sound a lot like a bingo parlor after the coverall gets hit though.....all the old ladies throwing down and markers and grumbling.
BINGO
