Do you REALLY like to play Sudoku puzzles? Are you the type of puzzler who loves the 16×16 and 25×25 grids, and also likes variety Sudokus, but has little interest in "boring" standard 9×9s? Well, great news! Here's a humongous 100×100 Sudoku, with diagonals, and here's the best part: This one is in color! No more bothering with those tiny black-and-white grids! With this book, you can go much, much further than that and create a much larger grid size, by cutting pages out and pasting or taping them together to form a 100×100 Sudoku. And what's more, each of the 100 individual 10×10 squares are subdivided into four 5×5 squares with different colors: red, yellow, green, and blue, along with gray squares indicating the diagonals. The gray squares along the long diagonals each contain the numbers 0 to 99. In addition, each color set has its own 25 different numbers from 0 to 99, which will be consistent throughout the entire grid, which you can deduce via crossing out numbers used on other color squares, using the scratch pads provided. As a result, when you combine any four 5×5 squares with the four different colors - whether those four 5×5 squares be in a 10×10 cage, all aligned in a row, in a column, or even on a long diagonal, as well as each set of "four corners" from the outermost corners of the grid to the centermost, or just in random, disparate places - they will end up containing all of the numbers from 0 to 99. How cool is that!
