Take the Sudoku challenge if you dare! Featuring five levels of difficulty, from very easy to very hard, these beautifully and logically constructed grids offer solvers just the right amount of difficulty, allowing them to stay focused and fully enjoy the experience. The creators, Sudoku master Anthony Immanuvel and puzzle guru Terry Stickels, know that if a puzzle becomes too stressful or frustrating, it's probably a flaw in the design--not the person doing it. Unlike lesser puzzles, these never have more than one possible answer, are pleasing to the eye, and involve no guesswork. They're a great way to keep the mind in tip-top shape! See if you can win this challenge match!
