How to solve Sudoku XV puzzles
A Sudoku XV puzzle consists of a standard Sudoku grid with the addition of X and V markers between neighbouring pairs of squares. X markers show all adjacent pairs of squares where the two values in those squares add up to 10, while V markers show all pairs where the two values sum to 5.
To solve Sudoku XV you must place 1 to 9, or 1 to whatever the size of the puzzle is, once each into every row, column and bold-lined rectangle while also obeying the X and V markers. It's really important to note that all possible pairs which sum to either 5 or 10 are marked, so if there is no 'v' and no 'x' then two squares do not sum to either 5 or 10.
Every Sudoku XV puzzle only ever has one possible solution, and it can always be reached via reasonable logical deduction. In other words, guessing is never required. Sudoku XV 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. These bold-lined rectangles are 2x3 for 6x6 puzzles, 4x2 for 8x8 puzzles and they are 3x3 for 9x9 puzzles.
