Sneaky Sudoku

Sharpen your brain with Sneaky Sudoku! Fill the 9 by 9 grid so every row, column, and 3 by 3 box holds the numbers 1 to 9 with none repeated. Four levels from Easy to Expert, pencil-mark notes, mistake highlighting, and a timed leaderboard. Play free online or print it out. Fun fact: Every proper Sudoku has exactly one solution, and the fewest clues that can still make one is just 17.
