For 2-players or teams, add the following rules to your game. If you’re playing in teams,
keep younger players involved by grouping them with older players.
1. The first major difference between 2-player/Team CLUE and classic CLUE is the setup. (See page 2 for classic setup).
- Follow steps 1 and 2 of setup as usual.
- In step 3, shuffle the rest of the Black CLUE cards together as usual. But then, before you deal them to the players teams, take the top four black CLUE cards from the deck and place them facedown in a row at the side of the board.
- Follow step 4 of setup as usual.
- But ignore step 5: you can never use the Red Bonus cards in a 2-player or Team game.
2. The second major difference in 2-player/Team CLUE is what you do when nobody
answers your question. (See page 4 for classic rules on asking).
- Ask questions as normal. The other player/team must always try to answer.
- But, if player/team cannot answer, you must secretly look at one of the four cards at the side of the board. Once you’ve crossed it off your CLUE Sheet, return the card to exactly the same spot at the side of the board.
- Every time the other team/player cannot answer one of your questions, secretly look at a different one of the four cards at the side of the board. (You’ll have to remember the places of the ones you’ve already seen!)
Everything else is exactly the same as classic CLUE!
