The easiest starting place is to find a "maximum cell"; that is, a numbered cell which if the walls are not at the maximum distance possible, the number is not satisfied. For example, in a 10x10 grid which has not started to be solved, a 19-cell is a maximum cell, since if the four walls are not at the edges of the grid, the number of cells ...
Another form of logic puzzle, popular among puzzle enthusiasts and available in magazines dedicated to the subject, is a format in which the set-up to a scenario is given, as well as the object (for example, determine who brought what dog to a dog show, and what breed each dog was), certain clues are given ("neither Misty nor Rex is the German Shepherd"), and then the reader fills out a matrix ...

Mathematical puzzles require mathematics to solve them. Logic puzzles are a common type of mathematical puzzle. Conway's Game of Life and fractals, as two examples, may also be considered mathematical puzzles even though the solver interacts with them only at the beginning by providing a set of initial conditions. After these conditions are set ...
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.
