Penalty Card Flip guide: play, fairness and friendly forfeits

How the game works

Start by choosing how many people are playing, from two to twelve. The app then suggests a number of penalty cards, about one third of the group, but you can change it with the plus and minus buttons. Every player gets one card, so the number of cards always matches the number of people. Next, look at the list of forfeits. The app fills it with ten gentle examples in your language, and you can edit, add or delete lines before you shuffle.

When you press the shuffle button, the cards are arranged face down in a grid. Anyone can tap any card to flip it. The card shows whether the person is safe or has a forfeit, and the name of the person whose turn it was appears next to the result. Once every card has been turned over, you move on to the results screen, which lists the forfeits of that round in a short summary.

• Choose the number of players, from 2 to 12.
• Adjust the number of penalty cards if you want more or fewer forfeits.
• Edit the forfeit lines or keep the examples as they are.
• Add player names if you want turns to show real names.
• Shuffle, then flip the cards one by one or all at once.

Why the shuffle is fair

A fair draw needs two things: an even chance for every card and an outcome that cannot change after it has been decided. Penalty Card Flip places all the cards in one step when you press shuffle. It uses the cryptographic random number generator built into your browser, the same kind of source used for security keys, and a method called rejection sampling so that no number is slightly more likely than another. The cards are then mixed with the Fisher–Yates shuffle, which gives every possible order the same probability.

Because the arrangement is fixed at that moment, the card someone taps makes no difference. Nothing is decided later, nothing is sent to a server and the result cannot be edited. The flipping animation only reveals what was already there. The same rule applies to the forfeit text: each penalty card takes a line from your list in random order, so the wording is as fair as the placement.

Keeping the evening fun and safe

A forfeit game works best when everyone is laughing with the player, never at them. Keep the forfeits light, short and easy to do in a room full of people. Singing a chorus, giving a one-line toast or doing a silly pose are good examples. Avoid anything that touches another person without consent, anything that targets a specific person’s appearance or background, and anything that would be unsafe to do while drinking. A good rule is that a forfeit should be easy to finish within a minute.

Drinks should never be part of the penalty. Nobody should feel pushed to drink more than they want, and everybody should know that they can say no. If someone does not want to do a forfeit, the group can swap in a different line or pick a gentler option together. The point of the game is the surprise and the laughter, not pressure.

• Keep each forfeit short enough to finish in about a minute.
• Never make a forfeit about drinking more or about touching someone.
• Let anyone skip a forfeit without shame, and swap in another line.
• Choose forfeits that suit the youngest and most shy person in the room.

Ideas for choosing good forfeits

The best forfeits are specific, a little silly and clearly finished when the person says so. Instead of a vague instruction, write something the group can picture: a line of a song, a toast in one sentence, a short self-introduction, or a movie-trailer voice for the next sentence. Mixing different kinds of tasks keeps everyone involved, because some people enjoy performing while others prefer quick and quiet tasks.

Think about the room before you shuffle. A work dinner needs different forfeits from a noisy student night. Write a few lines that reflect your group’s inside jokes, and you will see more laughs than with generic ideas. When the round is over, you can save the list for next time, or copy the result text to share it with the people who were there.
