Pre-game Phase:
Start taking signups for the game, make sure to keep everyone that signs up in a Player List.
Announce a deadline for when you are closing sign-ups either by listing a specific time (xx:30) or within a time frame (in 2 minutes).
Announce that sign-ups are closed, list the Player List one more time.
Beginning Phase:
Tell players to PM you a username from the Player List to attack.
Wait for players to send you attacks, highlight any players that haven't pmed you after a few minutes in main chat.
Set a deadline for when attacks must be in for those that haven't pmed you yet, if they haven't pmed you by the deadline, removed them from the game (modkill).
Allow users that attacked a modkilled player to re-pm you with another name from the Player List.
Attacking Phase:
Read your pms and announce a player attacking another player in main chat.
Use the .roll 100 command for the first player's attacking roll and .dice 100 command for the second player's defending roll.
The player who rolled the lower number is eliminated.
After all attacks are done, update your Player List with the users remaining. If more than two players are left, return to the beginning phase. If two are left, go to the Finale Phase.
Finale Phase:
Once there are only two players left, announce that the Finale is happening.
Use the .pick username1, username2 command to determine which player will have the attacking roll and which player is defending.
Roll like you would in the attacking phase, the player with the higher roll is considered the winner.
