Be careful when you buy this as it is extremely addictive. I play while listening to me audio books to keep my mind sharp.

I am one of your first customers since many years ago... Your state of the art games are my tools to keep me young. Sudoku Up is my favorite, many hours a day... Sudoku Up helps me to maintain my grey cells active. I recommend it to my sons and grandchildren to have fun and keep their minds open. Thanks TreeCardGames!!!
