Sapphire Software News

Sudoku Sensei has been nominated to Smartphone and Pocket PC Magazine’s best software of the year for 2006! We’re excited! Take a look at what they are seeing and you'll agree.

Sudoku Sensei is addictive, easy to use and all you could hope for in a Smartphone puzzle game. Learn the game and learn what everyone else knows. Sudoku Sensei is the best sudoku on the Smartphone.


Designed for both Adults and Children

The "Games for Big and Little Idle Hands" are designed for both children and adults. We do this by providing four (4) difficulty levels that are tested by the target users.

  • Easy - For young children, the game will play at a 3-5 year old level with some randomness to let the child win more often.
  • Normal - For older children, the game will play at a 6-9 year old level with a goal of trying to not pass up easy wins or losses.
  • Hard - For teenagers and adults, the default level will play like an adult new to the game and try to predict what would be the best move based on what the game thinks you might do next.
  • Expert - For the person wanting the hardest experience, the game will do significant analysis for the best moves, try to prevent falling into traps and lay down one or more traps in order to win.
Games you know and love

Each of our games is based on a game that is familiar to both your children and you. We have added some interesting twists to the original game to make it more challenging and enjoyable to play.
