Platinum Sudoku has 5 levels of difficulty for players of all skill levels, as well as three hint options to help you along in case you find yourself stuck. The first hint will give you all the possible numbers in a current cell. The second one will help you work out one number. The third hint, meanwhile, will scan the grid to mark all the cells that are right or wrong. As you complete a predetermined number of grids, the game will start to unlock challenges such as Subtract, Pair Match, Shuffle, Choice Block, High Sum and Mine Detector. You can also customize your game by changing your font, music, skin and grid. However you need to solve puzzles to unlock these options.

Don't let the girl at the start up menu scare you. When I played early in the morning, she asked me "morning already?" When I played outside of my regular time, she told me that I normally play at night and it's not nighttime yet. The first couple of times that this happened it freaked me out, and to be honest, it's still a little creepy! The game has a feature that allows the player to draw the number on the screen with their finger. However, I was having problems with this feature: the game wouldn't recognize my numbers, and created more aggravation than it was worth. I finally switched back to the number pad. I was also unable to change the player's name. It shows up as Julia every game. I know this is a small issue, but if I paid for the game I want to be able personalize it with my name.

You no longer have to go searching in newspapers for a Sudoku puzzle to play, all you need to do is open the Platinum Sudoku.
