I Know You Don't Card Game

I Know You Don't is a clever card game of guessing, deduction and pattern recognition where one player knows the secret... and everyone else is trying to figure it out!

Each round, one player becomes the Rule Keeper and chooses a secret rule. Everyone else plays cards and watches closely for clues, trying to determine which cards follow the hidden pattern—and which ones don't.

Every card played gives you another piece of information. Look for similarities, test your theories and use a little deduction to figure out what the Rule Keeper knows. Once you think you've cracked the code, use that knowledge to play your cards strategically and race to be the first player to get rid of them all. 

With five levels of difficulty, the challenge can grow along with the players, making it approachable for newer players while still giving experienced code-crackers something to think about. 

It's quick to learn, compact and perfect for family game night, travel, parties or anyone who loves puzzles, riddles and figuring out the answer before everyone else.
