Logic grid puzzles are a type of problem-solving game that requires players to use deductive reasoning to fill in a grid. The grid typically consists of categories and options, where players must determine the relationships between different items based on a set of clues. Each clue helps narrow down possibilities, allowing players to eliminate incorrect options and find the correct answers. These puzzles often involve scenarios with multiple characters, objects, or events, such as people, pets, or colors. Players create a visual representation of the information, making it easier to track relationships and solve the puzzle systematically.
