Mobile Game Application: An Android Puzzle Solutions

The client intent was to develop a fun puzzle game where user can test his logical and mental skill. They also had additional requirements as there should be no database which will store the puzzle but the application always generate a unique puzzle with a great speed, which was a test for Mindfire’s team as it was something really tough for this mobile platform. Because creating a unique puzzle each time it involved a huge calculation. The objective is to fill a 99 grid with numbers(1 to 9) so that each column, each row, and each of the nine 33 sub-grids that compose the grid (also called “boxes”, “blocks”, “regions”, or “sub-squares”) contains all of the numbers from 1 to 9. The puzzle setter provides a partially completed grid, which typically has a unique solution.
