@grayruby - sorry been less active lately. What about doing "Squares". For the entire tournament. Everyone gets assigned/buys in and gets random winner-loser numbers 0-9. You keep those numbers throughout the entire tournament and have a chance at winning in each game. Each round is worth a different amount. I have an Excel spreadsheet I built to do this a few years ago I can probably dig up and find if interested.

Edit to add, I'm in for any format.
