Sudoku is a challenging logic game that's easy to learn.  Like a crossword puzzle without words, the premise is simple: fill in the missing numbers in a puzzle grid so that every horizontal row, vertical column and 3x3 square contains each number from 1 to 9 without repeats.  The game uses numbers but there are no calculations.  Mathematicians have absolutely no advantage; it's all about problem solving, logic, reason and critical thinking skills - all the elements that make great puzzles so much fun!
