$10 entry. Registration at 1. Start time 1:30. End time 4:30. Head to head match play for 3 hours.  

Head-to-head match play on few enough machines that there’s at least a player or two waiting at all times. At the end of each game, the winner gets one point. The loser stays at the game unless they’ve lost twice in a row, in which case the winner stays. The person staying on the game plays in the same position (1up/2up) as they were already. First person from the queue comes and plays that player, the person that left the game goes to the back of the line and records the win and loss on a master list.

At the end of 3h, no more games may start. Most wins wins, ties broken by fewest losses.
