plan_b media releases 'SUDOKU - classical edition'
"A real mind sharpener for all ages! The Japanese logic game began appearing widely in newspapers and have become the morning brain breakfast for millions. Join the hype! Sudoku's just logical and involves no math. The objective is to fill a grid of 81 boxes, divided into nine three-by-three suqares, so that every row, column and square contains the digits 1 through 9. It's fun. It's challenging. It's addictive!"
