How to solve a Sudoku
Put digits in the empty squares such that in each row and in each column the digits 1-9 appear exactly once, and they appear exactly once in the 3 × 3 "blocks".
Turn on "Error Checking" in the Settings menu for some extra help (duplicate digits then turn red).
Solve the Light, Medium, & Heavy puzzles of one day and get a star! For each three Light puzzles you solve in one day you get a feather, for each three Medium a medal, and for each three Heavy an anvil!
