Do you REALLY like to play Sudoku puzzles? Are you the type of puzzler who loves the 16x16 and 25x25 grids, and also likes variety Sudokus, but has little interest in "boring" standard 9x9s? Well, great news! Here's a humongous 100x100 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 100x100 Sudoku. And what's more, each of the 100 individual 10x10 squares are subdivided into four 5x5 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 5x5 squares with the four different colors - whether those four 5x5 squares be in a 10x10 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!
