"Dr. Sudoku" Ships for Game Boy® Advance

A Game That Could "Increase Your Lifespan" Comes to the Most Popular

Handheld Game System

SAN FRANCISCO, CA April 26, 2006 Video game publisher Mastiff announced

today that it has shipped Dr.Sudoku for the Game Boy® Advance handheld video

game system to major retailers across North America. Dr. Sudoku is the

definitive handheld version of the puzzle phenomenon that is sweeping the

nation.

In addition to the hundreds of hours of brain challenging entertainment that

Dr. Sudoku offers gamers, recent studies suggest that games like Dr. Sudoku

can actually increase people's lifespan. According to a recent study

conducted at the University of Edinburgh, games such as Sudoku can awaken

'survival genes' that lay dormant in the human brain. These survival genes

make the brain cells live longer and resist disease, strokes and the effects

of drugs.

The Dr. Sudoku video game features 1,000 hand created puzzles, Original

Mode, which lets you create you own Sudoku puzzles, a tutorial mode, help

for those moments when you really are stuck, the ability to "pencil in"

possible solutions, and a puzzle problem creation mode. BusinessWeek.com

recently said that Dr. Sudoku "could be the next Tetris."

Sudoku looks like a math problem, but it's not. The rules are simple: start

with a grid consisting of nine three-by-three squares in which some of the

numbers are already supplied. Fill in the blank squares so that each column,

row, and three-by-three grid contains a number from 1 to 9 with none

repeated.
