Puzzled Numbers

Originally called 15 puzzle and also called Gem Puzzle, Boss Puzzle, Game of Fifteen, Mystic Square and more; is a sliding puzzle where you need to place the numbered tiles in ascending order.

This version of the game has 24 levels of increasing difficulty and introduces different puzzle sizes and shapes, apart from two new kind of tiles:

* Black tiles, that cannot be moved and block other tiles.
* White tiles, that also cannot be moved but other tiles can pass over them.

Try to solve the puzzles if you dare, they are very hard, specially the last levels.
