Sudoku is a mind game and a puzzle that you solve with reasoning and logic. Fill in the grid with numbers so that every row, every column and every 3x3 box has the numbers 1-9, without repeating any.
That's all there is to it. There's no math involved. The grid has numbers, but nothing has to add up to anything else. You solve the puzzle with reasoning and logic.
Solving time is typically from 10 to 30 minutes, depending on your skill and experience.
