The book presents a set of 100 puzzles. Solving each puzzle calls for a real genius in you. Considering the time it may require to solve a puzzle, we have restricted the number of puzzles to 100 in this publication. All puzzles in this book are computer generated with our own invented algorithm that is capable of generating all possible combination grids of sizes up to 81x81, and even beyond. As these puzzles are difficult to solve, we have also provided the solution to each puzzle in the book itself.
