The envelope is given to the player whose birthday is coming up next. This player is the first "Whoozit".
Everyone except the Whoozit receives four cards and the remaining cards are put face down in a pile. Players can look at their cards, but cannot show them to anyone else.
All the players other than the Whoozit put their chosen cards in the envelope without revealing them. The Whoozit then takes the cards out of the envelope and secretly puts them behind the corresponding tokens 1 least favorite, 6 for most favorite.
The Whoozit reveals the least favorite thing first, reading it aloud. The player who chose this card takes the 1 token and gets one point. The Whoozit continues turning over cards until all of them are revealed and one token from each stack is awarded.
After this process is completed, it's time for a new Whoozit. Everyone passes their cards to player on their left. The player with no cards takes the envelope and becomes the new Whoozit.
All the revealed cards are put in a discard pile. Everyone except the Whoozit draws more cards for a total of four cards in each hand. The game continues until everyone has been the Whoozit and all the tokens are awarded.
It is relatively easy to create a homemade version of the game by taking index cards and writing other nouns, names and verbs on them and by using any other form of scoring tokens like coins or poker chips. By using other scoring tokens, it is possible to have more than the game's self-alloted maximum of 7 players.
A different way of playing Whoonu includes having the same judge (or Whoozit) for everybody's category for one round. While that judge would be absent from scoring for that round and would not be able to submit any of their own cards for any of the categories in that round, all players would be absent from one round each, making it even.
A variation of that judging method is to have one judge deal out 6 cards to the other 6 players (or 5 or 4 players), but none to himself. (If there is only 3 other players, deal out 12 cards to each player; if 2 players, 18 cards each.) The judge will then make up 6 categories in a row to judge and the other players can only submit cards from the remaining cards in their hand; they are not allowed to draw another card from the deck. When it comes to the sixth category, the players have to submit what card/cards remain in their hand, no matter how relevant the card is the category.
