About Logic Grid
Logic Grid presents classic deductive reasoning puzzles where you must determine how multiple attributes — people, objects, locations, hobbies — relate to each other using only a set of logical clues. Each clue eliminates one or more possibilities from the grid, and the satisfying cascade of deductions that follows when you find a key insight is genuinely intellectually thrilling. Logic grids are used extensively in law school entrance exam preparation and corporate assessment centers because they measure the specific kind of constraint-satisfaction reasoning that predicts success in structured analytical roles. This browser version makes that rigorous training freely accessible.
