gFifteen - The Sliding Tile Puzzle Gameg.Fifteen is a graphical implementation of the old sliding puzzle game fifteen. It utilizes the gtk+-3 libraries and is targeted for the Gnu/Linux operating system.
The goal is to move the numbered tiles from a random starting position back into order from one to fifteen, with the empty space remaining at the bottom right. Tiles may only be moved one at a time and only by sliding a tile next to the empty space into that space. Simply click on a tile to move it.
