Colorku Solid Wood Puzzle

Sudoku puzzles have exploded in popularity in recent years, and this product allows you to enjoy the logical puzzles with colors instead of numbers. Instead of using numbers from 1-9, Colorku uses nine differently colored wooden marbles on a large wooden board. The high-quality wood board measures 11.5" x 11.5" and is divided into nine rows, nine columns, and nine 3 x 3 squares. It has 81 wood marbles in 9 vibrant colors. The board and marbles are covered with a plastic tray that holds the balls on the board when storing, and flips over to serve as a ball holder while playing. The board comes with 100 different puzzle cards that come in four different difficulty levels and tell players where to place the first few marbles. The solution to each puzzle is achieved when the player ends up having one and only one of every color ball in each of the nine rows, columns, and 3 x 3 squares. Solutions are included. There's even a color conversion card that shows you how to alter any Sudoku puzzle from any book or news-paper and solve it using your Colorku board. Think the 100 puzzle cards that come with the game won't be enough? Luckily, there are a few Expansion Packs, which offer additional puzzle cards at a variety of levels. Each pack offers 100 puzzles with solutions. The Beginner Puzzles are fairly simple, the All Level Puzzles offer puzzles for four different difficulty levels, and the Advanced Puzzles will drive you crazy. The durable wooden game and fun yet challenging puzzles will be enjoyed by new and old Sudoku fans alike. ~Rachel
