Put the whole office in the draw and let the balls do the talking. Share the link, print the sheet for the kitchen wall and follow it all the way to the final on 13 November.
One name per line. Someone buying two tickets? Put their name in twice. Every dollar collected goes back as prizes.
Every team goes to someone. If you have fewer than 24 tickets, the leftover teams are handed out at random as bonus teams.
Knock teams out as the tournament goes, then set the placings once the final is played on 13 November.
