da Vinci Castle

This is a family game to test your memory. Can you find the secret code hidden in the castle? In da Vinci Castle, you play the game on the assumption that Leonardo da Vinci has built six castles. He has a hidden a different secret code in each castle, and if you decrypt it, you can destroy it. Maybe it's a genius' eccentricity to hide these deadly weaknesses in the castle that he built. Each player receives a piece with a color and a piece with a number, creating a castle with a secret password. And when it's your turn, you either ask questions or attack. You can ask questions only to the player on your left. Choose a color and a number and say, "Do you have red or four?" If the player who was asked has either, they say yes, if they have neither, then the player goes on to say no. Ask questions to get a clue to what the other player's secret password is. Once you are sure what the other player's secret password is, you can attack your opponent and destroy their castle. However, if you attack your opponent's castle with the wrong secret code, you must be careful because your castle will collapse and you will be eliminated from the game. —description from the publisher
