How to solve SudokuX puzzles
A SudokuX puzzle consists of a grid, usually 9x9 but sometimes smaller or larger, where you must place 1 to 9, or 1 to whatever the size of the puzzle is, once each into every row, column, boldlined rectangle and main diagonal region  these diagonals are always marked to remind you.
When you first start a SudokuX puzzle some of the squares are already filledin, and your task is to fill in the rest. SudokuX is a logic puzzle, so you solve them via small logical steps rather than simple guesswork. In order to do this it's often helpful to place small pencilmarks into the grid to keep track of possibilities for a square  you can do this on puzzlemix too.
Look at the solved puzzle on the left. Notice how not only each row, column and boldlined rectangle has one each of 1 to 6 in it but also each of the two marked diagonals do too. If this was a 9x9 puzzle then there'd be one each of 19 in each of those regions.
SudokuX 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 16, 18 or 19 once each into every row, column and boldlined rectangle.
