Boston Belles October Women's Tournament will try out a new location and a new format. Here's a bit about Flip Frenzy from the Matchplay description:

Flip Frenzy tournaments (also known as Pinball! Pinball! Pinball! tournaments) are, as the name implies, very hectic tournaments. The tournament organizer sets a duration for the tournament (2.5 hours for this one!) and a number of machines to be used for the tournament. When the tournament starts, head-to-head matches are created on those machines, and any players not assigned to a match are placed in a queue.

When a match ends, a new game will be created using the following approach:

Player 1 will become Player 2 on the new game.
Player 2 will go to the bottom of the queue.
The player at the top of the queue will become Player 1 on the new game.
The tournament will progress in this manner until the timer runs out. The winner is the player with the most net wins (or total number of wins minus total number of losses).
