When you first open a puzzle some of the squares are already filled-in, and your task is to fill in all of the remaining ones. Since Sudoku is a logic puzzle, the intention is that you do this without guesswork - instead logical deduction is the intended method, and this is where the fun comes in. It's also important to note that despite using digits, there is absolutely no mathematics involved! You could use pictures or letters or any other set of symbols you liked.

Look at the solved puzzle on the left. Notice how each row, column and bold-lined rectangle has one each of 1 to 6 in it. That's because this is a 6x6 puzzle. In a 9x9 puzzle there'd be one each of 1-9 in each of those regions.

Sudoku puzzles on puzzlemix appear at a wide range of sizes and difficulties. Usually they are 6x6, 8x8 or 9x9, in which case you must place 1-6, 1-8 or 1-9 once each into every row, column and bold-lined rectangle. The bold-lined rectangles are 2x3 for 6x6 puzzles, 4x2 for 8x8 puzzles and they are 3x3 for 9x9 puzzles.

Occasionally puzzlemix will feature a larger Sudoku 12x12 or even Sudoku 16x16 puzzle. In these cases you must place 1 to 9 and A to C, or 1 to 9 and A to G respectively, into each row, column and bold-lined box.
