Celebrating U.S. History I: Presidential Sudoku: Mingling Words & History with Sudoku

Updated to include 2020 election results!. This Sudoku puzzle book challenges you to uncover the names of each American President, Vice President and First Lady who have served the U.S. since its founding. The first twist: The letters you use to spell out those names are found by solving word Sudoku puzzles.. Classic Sudoku puzzles always use the same symbols to fill in cells: the digits 1-9.In word Sudoku, however, each puzzle has a different set of symbols - the letters in a word or phrase. The puzzles are a little bit harder than classic Sudoku because you have to learn the allowable symbols all over again each time you begin a new puzzle.. The second twist: Don't expect to find the Presidents listed in order of their service to the country. That's too easy!
