Playing Multiple 1's, III

Question

• It is the first turn of the game.
• Alice clues number 1 to Cathy, touching two cards on slot 3 and 4.
• Immediately, Bob clues number 1 to Cathy, touching the same two cards.
• What notes should Cathy write on her cards. What should she do next?

Solution

• Alice's clue tells Cathy to play the 1's from right to left.
• Bob's clue is a Fix Clue (That Gives No Additional Information).
• This means that Cathy should not play the expected card (slot 4), but skip to slot 3 and play that card instead.
