We did a home tournament with an unusual and very loose format. All the games were preset with extremely low high score tables, and had everyone choose what games they want to play and whom to play with. It was just friends and family. Play as many or as few games as you wanted, at the end of the evening time was called for last games in progress and then donated prizes and a high score certificate awarded to the top posted scores.
This is may not be a good tournament format for cash prizes, but works good enough for friends and family. Even non-pinheads even have a chance to get that lucky great game. Everyone gets a taste of competition and even if a player doesn't hold a high score, they often get the experience of at least putting initials up on the board that they may not get to experience at any other time. It's also super easy for the tournament host to administer.
