A Card-Flipping Psychology Logic Puzzle
The card-flipping numbers and colors logic puzzle is deceptively easy. Here are the rules to the Psych2Go brain teaser: There are four cards laid out in front of you. One shows 11, one shows 8, one shows blue, and the last one shows red. For each card, one side has a number and the other side is colored. If a card has an even number on one side, the other side must be red—but one card breaks this rule. Which card or cards are necessary to turn over to find the card that breaks the rule? Watch the video below for the answer, or scroll down to read the answer. Good luck!
