    Most puzzle solvers try to solve such puzzles by mechanical manipulation, but some branches of mathematics can be used to create a model of disentanglement puzzles. Applying a configuration space with a topological framework is an analytical method to gain insight into the properties and solution of some disentanglement puzzles. However, some ...

    The fact that the puzzle has a unique solution allows for additional deductions. For example, there may be a long area on a border, with multiple black squares one space away. Placing the light by any of them will light up the exact same squares. Since there is exactly one solution, a bulb in any of them would be a contradiction.
