Sudoku puzzles come to Android devices

1/23/2017

My local newspaper keeps getting smaller and among the casualties of the squeeze is the daily Sudoku puzzle that appeared among the daily comics. The puzzle had been a regular feature in many newspapers since the game hit the US in the early 2000s.

The game has a particular appeal to people who like to work with numbers. The objective is to fill a 9x9 grid with digits so that each column and row, plus each of the nine 3x3 sub-grids, contain all of the digits between 1 and 9 with no duplication.

Today, most puzzle fans are probably playing electronic versions like Sudoku Free, an app designed for Android phones and tablets. Like the printed versions, the app presents a grid that is partially populated with numbers. The challenge for players is to fill in the open squares with the correct digits.

Sudoku Free has three difficulty grades - Easy, Medium and Hard - and multiple levels in each grade. It will check for errors and save unfinished games and it has an auto-fill mode that can be set as on or off.

Sudoku Free is available as a free download in the Google Play Store.
