Hi all! I've just made a little, mobile HTML5 game: Boss Puzzle. - Boss Puzzle (often referred as Game of Fifteen) is a game that consists of a frame of numbered square tiles, in random order, with one tile missing. The object of the game is to put all the tiles in the correct order, by making sliding moves that use the empty space. The correct order is the numbers ascending order, row by row. For example, with 8 tiles, the correct order will be this: 1 2 3 4 5 6 7 8 This mobile HTML5 game allows to play with either 15 or 8 tiles. I've tested it on an iPod Touch (4th gen), iPad (3rd gen), Nexus 7 and Nokia Lumia 520, and it works perfectly. If you have other devices, please let me know if everything works well. Thank you in advance for your feedback!
