Rubik’s Sudoku  comes in a nice box (like most puzzles I have from Think fun – formerly known as Binary Arts) with a small drawer where you can store pieces of the Sudoku puzzle and the booklet. In this booklet you can find tips and a explanation how to solve Sudoku’s and 100 Sudoku puzzles at different levels.

Buy Rubik’s Sudoku from Amazon.com. Happy Puzzling!
