Stand Up 2 Cancer Sudoku is a collection of Sudoku games that will benefit the high-profile Stand Up 2 Cancer initiative. It's fun, and perfect for the number-averse: players use the letters that make up STANDUP2C instead of numerals as they fill in the grid. It's Sudoku with a twist--a great gift, a great companion for a long trip, and a great way to support a worthy cause. There are 102 puzzles that range from easy to difficult, and information on the SU2C initiative is included. Stand Up 2 Cancer Sudoku is a product of Brandoku, a company founded by entrepreneur Cal Rogers that creates specialized Sudoku games for various institutions and causes, including the Susan G. Komen For the Cure.
