Rules for organizing, conducting, and participating in online Heroes of Might and Magic III tournaments.

We could create a special online randomizer.
Alternatively, we could use an existing one, like the one used on the forum to select castles. For example, we create a list of 8 castles numbered in order, and players choose odd or even. The winner is determined by the number of the first castle from the resulting pair. If a castle not on the list (the ninth) is selected, the randomizer is restarted.
