"I Know... You Don’t" is a clever and fast-paced family card game where players must use logic, deduction, and pattern recognition to crack a secret rule known only to the Rule Keeper. Take turns being the "Rule Keeper" who chooses the rule that everyone else must try to figure out. Each card played is a clue, giving all players the chance to detect what the pattern might be. If you can crack the code, use it to shed your cards and win! With five levels of difficulty built into the rule cards, the game grows with your group and ensures every round feels fresh and challenging. 3-7 Players. Ages 10+
