Basically, this works in almost the same way as the Tag Team Dueling, only you have no partner. So let's recap:

1. All Players CANNOT attack on their first turn: So every player must have had one turn before a battle can be carried out.

2. Cards affect the player you choose: Let's do an example. Dark Hole usually would destroy yours and your opponent's monsters, but in a Tag Team or Battle Royale, duelists usually mistake the rules and destroy EVERYBODY'S monsters. However, this is not the case. For Dark Hole, you must destroy all of your monsters and CHOOSE ONE other opponent for the card to work on. This applies to all other cards like that.

3. Blocking attacks with monsters: Although it is every man for him/herself, you may want to block an opponent's attack on another opponent. Although I currently can't think why, it can be done. However you can only block if the attack is a direct attack.

There is one more thing here that you may decide to do. It's about who goes first. You could just flip coins, or you COULD do it the way the Anime does it. Each duelist chooses a monster out of their deck. The duelist whose Monster has the highest attack power can choose the order of turns. NOTE: The monsters chosen are then removed from play before the duel begins, and that sucks.
