Hi,
Perhaps you could clarify what information you are looking for.
Normal practice is to have draw for the button as usual, all normal TDA/Tournament Poker rules apply as usual, there are no changes to the rules.
With regard to seating you can have tournament software decide seating or draw with cards, chips, dice etc. I would then take the winner from each table onto another game by either a redraw or a specific order for example table 1/2 play each other etc.
Regards
Stuart
