None of a kind is the challenging no-match brainteaser game. Wait - it says "blue," but it's printed in red. What's going on? This multi-player brainteaser game is designed to befuddle, and strengthen, your brain. Everyone plays at once as you race to match up cards that don't match - it sounds easy, but it's surprisingly challenging. After you play a few rounds, you'll see why this game. . . Has no match! None of a kind is based on the stroop test, one of the most-cited papers in experimental psychology. It studies the relationship between the brain's processing speed and executive functions, focusing on regions of the brain involved in planning, decision-making, and managing real-world interference, such as multi-tasking. In other words, playing none of a kind improves your brain's processing speed! How to play: pick your card to start your row. Then find a card that does not match the color of the word, color of the ink, or number of words on your card. The player with the longest row earns the highest point card in a race to score the most points! Recommended for 2 to 6 players, ages 7 and up. Made in China.
