SETUP FOR I SHOULD HAVE KNOWN THAT

HOW TO PLAY I SHOULD HAVE KNOWN THAT

Here is how to play I Should Have Known That, the fun trivia game.
First things first, keep in mind, everyone starts at 0 points.
THE FIRST QUESTION
The scorekeeper starts the game by taking a card and asking the player or team on their left the top question on the card. That player must either answer the question or skip. If they skip, that player’s turn is over. They do not lose any points for skipping their turn.
THE SECOND QUESTION
When skipping turns, the scorekeeper must ask the next player the second question on the card. Again, this player has a choice to answer the question or skip their turn.
And so on.
A CORRECT ANSWER
Now, if a player decides to answer the question and answers it correctly, the scorekeeper lets them know that it was correct. They do not gain or lose any points.
AN INCORRECT ANSWER
However, if a player decides to answer the question and answers it incorrectly, the scorekeeper turns the card to see how many points they lose. Mark these points down somewhere to keep track of the points.
ADDITIONAL RULES
Now, the above rules are all that are written on the I Should Have Known That box, but this obviously comes with a massive flaw: you could technically skip every question and still come up on top, as you only get a penalty for an incorrect answer. This does not properly incentivize players.
So, here are a couple of I Should Have Known That rule variations to make the game more competitive and playable:
- If you get a correct answer, you can penalize another player of your choice with the negative points you would have gotten for an incorrect answer.
- You cannot skip more than three questions in a game.
END OF GAME
Whoever has the score closest to 0 at the end of the game wins!
