    Marbles Gift Wrap


    Marbles offers gift wrapping on this brainy product for only $1!
    We haven’t lost our minds, we just know how nice it is to avoid those dull scissors and tape that won’t tear. To add gift wrapping to your order, just select the “yes” button under the “add gift wrap” section.

    Place one ball of each color in every row, column and square to complete each challenge.

    Rely on a large network of brain areas as you identify patterns and missing pieces.

    More than 100 puzzle cards give you starting formations ranging from beginner to expert.

    ColorKu is a Sudoku-like game with color marbles instead of numbers that exercises all four lobes of your brain in one fell swoop. In other words, it's kind of like those "miraculous" machines they advertise on late-night infomercials claiming to exercise your entire body with one simple move. Except in the case of ColorKu, it's true. And you can get the aforementioned quadruple lobe workout without the annoying spokesman and "Just 17 easy payments of $42.95 each!" Yep, for under 40 bucks, you can get a beautiful solid wood game board, countless fun game nights and one heckuva brain workout.

    The Marbles BrainCoach says...

    Colorku is a great Sudoku option for people who may not love numbers, it's so pretty and colorful, and looks great if you leave it out on display. It comes with over 100 puzzles, which makes it a great value, too.
