The 15 puzzle app for Android is a classic puzzle game that features sleek design and a variety of grid sizes to choose from. The goal of the game is to rearrange the tiles on the grid so that they are in numerical order, with the empty space at the bottom right. The app allows users to select different grid sizes, providing a range of difficulty levels to choose from.

One of the standout features of this app is its sleek design, which makes it easy to use and visually appealing. The tiles are easy to move and the interface is intuitive, making it a pleasure to play.

In addition to its great design and range of grid sizes, this 15 puzzle app is also open source. This means that the source code for the app is available for anyone to view and modify, making it a great choice for those who are interested in learning more about app development or contributing to the project:
