Enjoy the contemplative fun of sudoku with this handmade game designed by Thai artisan Waraporn Khamsuk. Crafted from raintree wood, the 3D game features movable numbered cubes that form the 3x3 grid of a larger, single cube. Like 2D versions of sudoku, you must arrange the cubes so that each face of the whole cube contains one of each number from 1 to 9. The game comes with a clear acrylic box for keeping the pieces safe.
