The Set game was invented by Marsha Falco. Her work in genetics involved using cards with different symbols to represent genetic traits. As she was analyzing these cards, she noticed a particular type of relationship among certain groups of three cards. This relationship was based on the characteristics of the symbols like color, shape, number, and shading. She realized this could be turned into a game. So, she created the rules for the Set game. Since then, it has been enjoyed by many people around the world for its unique gameplay that challenges the mind's ability to recognize patterns.
