You will need to decide which alternative Truth or Dare rules apply when someone does not want to fulfill a dare or answer a question, and if you play with penalties - and which.
In case someone does not want to do a dare, arguing that it may be too hard (or embarrassing) to do, but all other players decide it is okay:
He needs to do it!
The group must decide beforehand (or just improvise in mid-game) if penalties are appropriate for not fulfilling a truth or a dare.
They should also think about which Truth or Dare house rules are the most fun for them.
Think about it like this:
If one always had the option of saying “I’m not doing this dare” without any penalty, then the game Truth or Dare will simply lose its fun!
Imagine everyone just skipping any Truth and Dare they do not want to do...
Typically, the group will decide on another dare which is harder, more difficult or more embarrassing. That would be for the first time a player denies a dare.
Then, he may change his mind and hurry up to say: “no, no I will do the first dare!” If the group is lenient, he can do it - if not, the group might decide “no, you have lost your chance! You should better have chosen the first option in the first place. Now you will have to do the penalty dare!”
This will be something very embarrassing. They could choose to blindfold you for the same dare, or even bind you to your seat for several rounds!
This will be fun to watch for the whole group and has an educational effect:
After one person has been punished by these strict Truth or Dare rules, the next player will think three times before refusing a dare! Often, telling the story of a player who has been punished in the past will be sufficient to ensure that everyone makes a fool out of themselves without resisting too much.
Whenever you give someone a punishment dare, don't take it personally! Have a drink with them, give each other high fives, and continue to have a great party!
