- If a player had the information to make a different decision, and it doesn't affect the subsequent turns taken by other players, "rewinding"/"redoing" according to the agreement of the whole group is allowed. This at first seems to be something which would slow down the game, but in reality, it makes it faster, because people can take their turns relatively quickly rather than going very slowly to ensure that they have evaluated *EVERY* possibility before taking their turn. This works better for euro style games, where there's only sort of tangential player interaction.
- For book-keeping heavy games, announce your moves, indicate to the next player that you have finished your public moves and are merely completing a transaction with the bank/rearranging something on the board according to your stated intentions etc.
We also have House rules for house rules:
- Write them down, so they can be rules-lawyered like any other.
- If there is a dispute about the interpretation of a rule, and we are playing with an even number of players, roll a die to determine the interpretation to be used for that instance of the game, and apply consistently.
- If a rule has been misinterpreted for the first portion of a game, play the rest of the game "wrong" to be fair, but make sure it's clear and clarified at the end of the game, and before the next game is begun.
Most of these we have only ever needed these for Killer Bunnies, but we have about 7-9 house rules for that.
