    Welcome to - play Kakuro online
    A site

    Kakuro is a puzzle game that's a cross between both traditional crosswords and Sudoku.

    Just like Sudoku you must fit the digits 1 to 9 into a grid of squares so that no digit is repeated within a defined area. And just like a crossword there's a grid of filled blocks and clues to solve.

    In Kakuro, there are across and down clues, just like in a crossword, but they give the sum of the digits in the relevant areas - which is why the puzzles are also called Cross Sums. The clues are written within the grid, to the left or the top of the area they apply to.

    [Unique online Kakuro player]   Playing Kakuro in our unique player is much easier than with pencil and paper. You can place both solution and pencil mark digits (working to help you decide which numbers go where), and you can resize it as big or small as you like. Plus you can even save your game - complete with pencil marks - and come back later.

    Want to jump straight in? Then just click here. It's not as hard as it sounds, since it only ever uses very simple addition. And if even that's too much then we have a handy reference that contains all the maths you'll ever need!
