The simplest way to run a tournament is to use
Blindvalet.com. Here is how to set it up:
- Choose the total number of players, 4 hours for duration, 15 minute blinds.
- Click on the checkbox for rebuys.
- Choose chips denominations of 25-100-500-1000. Put in 3K or 4K chips per player.
- Make the initial small blind 25.
- Put in your best guess at the number of rebuys. If you have a cautious group of players, it will probably be about half of your player pool size.
OK, the words "Chip Distribution" is a button. Click it to see how many of each chip to give each player.
Now click on "Payout Structure" above where you put in all these settings. It should default to paying 3 players, which is what you want. Just enter the buyin and rebuy amounts, and you are done.
Click on "Tournament Clock" and you are ready to start your tournament.
As a side note, you're going to have a hard time adding players later, unless you put their stack on the table and blind them off. As long as they won't be more than an hour late, that should be fine, if you are willing to do that.
